What Is a 200 kVA Servo Stabilizer?

A 200 kVA servo stabilizer is an oil-cooled, three-phase voltage stabilizer rated for 200,000 VA, or about 160 kW at a 0.8 power factor. A motor-driven variac and buck-boost transformer on each phase hold the output at 410V ±1% phase to phase when the mains rises (swells) or falls (sags). One unit protects a whole plant or building.

It is also called a 200 kVA servo voltage stabilizer, a 200 kVA 3 phase servo stabilizer or a 200 kVA automatic voltage regulator (AVR). Buyers also search for a 200 kVA voltage stabilizer, a 200 kVA servo controlled voltage stabilizer or a 200 kVA industrial voltage stabilizer. Other names include a 200 kVA automatic voltage stabilizer and a 200 kVA heavy duty voltage stabilizer, and some buyers simply type servo stabilizer 200 kVA. It is sometimes spelt 200 kVA servo stabiliser or typed as 200kva. A 200 kVA rating means 200,000 volt-amperes, not 200 watts.

The variac is a variable autotransformer, often called a dimmer, turned by a servo motor. A three-phase unit has one variac, buck-boost transformer and servo motor for each phase. It corrects everyday voltage fluctuations smoothly, without steps, so machines get a stabilized supply and continuous voltage stabilization. For a step-by-step explanation, read how a servo stabilizer works. SG Power's KNEUTRON range covers 10 to 500 kVA within its servo voltage stabilizer lineup.

200 kVA Servo Stabilizer Price List in India

The 200 kVA servo stabilizer price in India depends mainly on the input voltage range, balanced or unbalanced design, and build quality. SG Power quotes each 200 kVA unit on request after a free load and site-voltage check, so the price matches your site. Complete oil-cooled 200 kVA units listed online mostly cost about ₹2,00,000 to ₹4,50,000.

Why 200 kVA Prices Vary Online

Online, 200 kVA stabilizer prices range from about ₹42,000 to over ₹6,50,000, because sellers list very different products under the same rating. Input range, design, efficiency, oil and GST all change the figure. Listings under ₹1,00,000 are usually for air-cooled units, range listings or errors.

One published price list for unbalanced, oil-cooled units with a 400V ±1% output shows how much the input range alone changes the price:

Input Range (phase to phase)About the Same per PhaseListed Price, Excluding Oil and GSTOil Quantity
340–470V196–271V₹3,00,150about 650 litres
300–460V173–266V₹3,47,760about 700 litres

This is another seller's published list, not SG Power's. Prices are indicative. For the latest price, contact SG Power.

The widest range costs more than twice the narrowest, and that list excludes oil. Compare the input range, design and total delivered cost, not just the headline 200 kVA 3 phase servo stabilizer price.

How to Check a 200 kVA Listing Before You Buy

To check a 200 kVA listing, match its phase, power, current, input range, efficiency and oil against a true 200 kVA three-phase unit. Online listings sometimes show an air-cooled or single-phase 200 kVA unit, a single input figure, or a weight too low for the oil. Each points to an error or a different product.

Low Voltage at Your Site? Custom Input Ranges for 200 kVA

A 200 kVA unit for low-voltage sites can be built with a wider input range, such as 140–280V per phase, instead of the standard 170–280V. It suits industrial areas where voltage often drops below 170V per phase. A standard stabilizer would cut off there, while a wide-range model keeps correcting.

Record the lowest voltage on each phase over a few days, including peak hours. If it stays above 170V, the standard range is enough and costs less. If voltage stays low all day, ask your electricity distribution company (DISCOM) to check the transformer tap setting first.

How Much Load Can a 200 kVA Servo Stabilizer Run?

A 200 kVA servo stabilizer can run a load of about 160 kW at full rating. For safe everyday use, keep the running load to about 128 kW, which leaves a 25% margin for the surge when motors, compressors and lifts start. Spread the load evenly across the three phases.

How to calculate the kVA you need, in four steps

1

Add up the rated power (kW) of every machine that runs at the same time.

2

Divide by the power factor, usually 0.8, to convert kW to kVA.

3

Multiply by 1.25 to add a 25% margin for motor starting current.

4

Choose the next standard rating: from 151 to 200 kVA means a 200 kVA unit; above it, choose 250 kVA.

Sizing formula: Required kVA = (running load in kW ÷ 0.8) × 1.25. For example, a 120 kW load needs about 187.5 kVA, so 200 kVA is the right size.

If you know the current instead: kVA ≈ 0.72 × the highest current per phase at 415V. About 278 A on the most loaded phase means 200 kVA.

If your motors are rated in HP: multiply HP by 0.746 to get kW. A 128 kW running load is about 170 HP, so a single 200 HP motor (about 149 kW) needs a 250 kVA unit, not 200 kVA.

Leave out loads that do not need it: heaters, ovens and furnaces work on almost any voltage. Keeping them on a separate feeder and stabilizing only motors, machines and electronics can cut the stabilizer size and cost.

200 kVA Single Phase Servo Stabilizer: Is It Practical?

A 200 kVA single phase servo stabilizer is rarely practical. At 230V it would carry about 870 A, which needs very heavy cables, switchgear and a dedicated supply. Utilities in India supply loads of this size as three phase, so a three-phase unbalanced 200 kVA unit, correcting each phase separately, is the usual choice.

Single Phase 200 kVAThree Phase 200 kVA
CurrentAbout 870 A at 230VAbout 278 A per phase at 415V
SupplyNeeds a dedicated single-phase feed, not a normal utility connectionStandard three-phase, four-wire LT or HT supply
Cables and breakersVery large conductors and switchgearNormal industrial sizes for 278 A per phase
Single-phase loadsAll on one phaseSpread over three phases; an unbalanced design corrects each one

SG Power's single-phase servo stabilizers come in 10 kVA and 15 kVA, and its 200 kVA units are three phase.

Why Is a 200 kVA Servo Stabilizer Oil Cooled?

A 200 kVA servo stabilizer is oil cooled because its transformers carry about 278 A per phase at full load. Oil removes that heat far better than air; this cooling method is called ONAN (oil natural, air natural). SG Power's air-cooled range stops at 50 kVA, so every 200 kVA oil cooled servo stabilizer suits continuous, heavy industrial duty.

What Oil Cooling Gives YouWhat to Plan For
Steady temperature under continuous full loadA firm, level plinth for a heavy unit
Better tolerance of hot, dusty and humid sitesOil level checks every three months
Longer insulation life in 24×7 operationYearly oil testing and top-up with transformer oil to IS 335
Suits factories, cold storage and process linesSpace around the tank for airflow, cable entry and servicing

200 kVA Stabilizer Size, Weight and Oil

A 200 kVA oil-cooled servo stabilizer is a heavy, floor-standing cabinet with an oil tank. Published price lists show about 650 to 900 litres of transformer oil for 200 kVA, depending on the input range. Oil alone at that volume weighs well over half a tonne, so ask for the exact weight with oil.

Ask for exact dimensions before planning the room, and check that doors, ramps and the floor can take the unit. Ask whether it sits on a skid base or wheels, and whether the first oil fill is included in the price.

Balanced or Unbalanced 200 kVA Servo Stabilizer?

A balanced 200 kVA stabilizer corrects all three phases together, while an unbalanced one corrects each phase on its own. Balanced suits three-phase motors and production lines that load each phase equally. Unbalanced suits hospitals, hotels, malls and buildings where each phase feeds different single-phase loads, such as ACs and lighting.

BalancedUnbalanced
How it correctsAll phases togetherEach phase separately
Best forMotors, CNC machines, injection moulding, compressorsHospitals, hotels, malls, commercial buildings
CostLowerHigher

SG Power makes both balanced and unbalanced 200 kVA designs. An unbalanced model also copes with phase imbalance coming from the supply, such as one low phase at the end of a long line. Large oil-cooled models carry a separate meter for each phase, so the operator can watch all three phases at a glance.

200 kVA Servo Stabilizer Specifications

These 200 kVA servo stabilizer specifications are for SG Power's oil-cooled, three-phase, four-wire model.

200 kVA Features and Protections

Every SG Power 200 kVA unit has a KNEUTRON digital controller, a front-panel display and ±1% voltage regulation. Its protections cut off the output on over-voltage, under-voltage, overload, phase reversal and single phasing, with an adjustable trip time delay. Calibration is done on a touch-pad, without potentiometers.

The display shows: phase-to-neutral and phase-to-phase voltage, frequency and the output current of each phase, with Start, Stop and Menu keys on the front panel. True RMS sensing samples the voltage at a high rate, so the reading and correction stay accurate. You can set the output voltage and the input voltage band, and choose manual or automatic start and stop.

ProtectionWhat It Guards Against
Over-voltage cut-offHigh mains voltage reaching machines and equipment
Under-voltage cut-offVery low voltage that overheats motors
Overload cut-offLoad above the set limit; the display shows “Overload”, and the output restarts once the load is reduced and Start is pressed
Trip time delay (3–200 seconds)Compressor and motor damage when power returns after a cut
Phase reversal cut-offWrong phase sequence that can run motors and lifts backwards; the display shows “Ph. Reversal”, and the unit restarts once two incoming phases are interchanged and Start is pressed
Single phasing protectionLoss of one phase, which can burn out three-phase motors

Where Is a 200 kVA Servo Stabilizer Used?

A 200 kVA servo stabilizer is used where a three-phase running load of about 97 to 128 kW needs constant voltage despite mains fluctuations. Typical users are factories, plastics, textile and printing units, machine shops, hospitals, hotels, malls, cold storage plants and large commercial buildings.

200 kVA servo stabilizer for factory use: a 200 kVA industrial servo stabilizer for production lines, pharma, food processing and packaging machines, chillers and boilers

200 kVA servo stabilizer for CNC machines: sixteen to twenty mid-size CNC lathes or VMCs on one supply; for drives with heavy harmonics, ask about a K-rated isolation transformer

For plastics, printing and textile units: injection moulding machines, offset presses, looms and their chillers and compressors

200 kVA stabilizer for hotels, malls, institutions and apartments: ACs, VRV/VRF systems, lifts, pumps, kitchens and lighting across several floors

For cold storage, water bottling, industrial RO and process plants: compressors, pumps and filling lines that run round the clock

For data centres, telecom, IT, SCADA and research sites: equipment rooms, servers, control systems and laboratories, with the UPS after the stabilizer

200 kVA stabilizer for hospitals: multi-speciality hospitals, usually with an unbalanced model; pair with an isolation transformer for sensitive medical equipment

Servo Stabilizer Advantages and Limitations at 200 kVA

At 200 kVA, a servo stabilizer's main advantages are a precise ±1% output, smooth stepless correction and full load carried continuously. Its limitations are carbon brush wear, slower correction than a static stabilizer and no electrical isolation, so fast spikes still need a surge protection device.

AdvantagesLimitations
±1% output on SG Power models, smooth and steplessCarbon brush and variac track wear, so a yearly service is needed
Handles full load continuously, including motors and liftsCorrects more gradually than a static (IGBT) stabilizer
Lower cost than a static stabilizer of the same ratingNo galvanic isolation; add a surge device, or an isolation transformer for sensitive loads

SG Power's KNEUTRON 200 kVA models use a dimmer-type variac with a buck-boost transformer. Linear servo designs, and rolling-contact designs that use a roller instead of a carbon brush, are also sold at this rating. SG Power makes linear servo voltage stabilizers too.

How Is a 200 kVA Servo Voltage Stabilizer Beneficial for Big Companies?

A 200 kVA servo voltage stabilizer benefits big companies by holding every phase of the plant supply within about ±1%, whatever the grid does. Motors run cooler, PLCs and drives stop resetting, and production lines avoid unplanned stops. One mainline unit protects a whole building or plant section from a single point.

BenefitWhat It Means for a Big Company
Less downtimeFewer trips and resets on CNC lines, presses and process plants
Longer equipment lifeMotors, compressors and drives avoid overheating on low voltage and stress on high voltage
Steadier product qualityFewer rejects in printing, moulding and textile lines when the voltage dips
Lower repair costsFewer motor rewinds, drive repairs and control card failures
One point of protectionOne mainline unit replaces many small stabilizers across a building
Works on grid and DGInstalled after the changeover, it protects the load on both supplies
Supports UPS systemsKeeps UPS units on mains, so their batteries cycle less

A stabilizer does not cut the electricity bill or stop lightning spikes, so pair it with a surge protection device. Its value is fewer breakdowns and steadier output.

How to Choose 200 kVA Servo Stabilizer Manufacturers and Suppliers

To choose between 200 kVA servo stabilizer manufacturers and suppliers, first check that the unit suits your load, phase balance and lowest site voltage. Then compare regulation, efficiency, protections, oil-cooled build, in-house manufacturing, testing and local service. Ask each seller these nine questions:

1

Do you manufacture the stabilizer, or resell another company’s unit?

2

Is it balanced or unbalanced, and what input range does it cover per phase?

3

What output regulation, efficiency, correction rate (volts per second), response time and short-term overload capacity does it have?

4

Are the transformers made and tested in-house, and how much oil does the unit hold?

5

Does it include over- and under-voltage, overload, phase reversal and single phasing protection, plus a time delay?

6

Is there a routine test report, a user manual, and sites where your units have run for years?

7

Are GST, freight, installation, a bypass switch or bypass MCCB, an input MCCB and the first oil fill included?

8

Who services it near my site, are carbon brushes and control cards available locally, and what AMC and warranty terms are offered in writing?

9

Will you check the site’s power quality before quoting, and is remote monitoring or data logging available?

What to Include in a 200 kVA Servo Stabilizer Tender Specification

A good tender specification for a 200 kVA unit lists the rating, input range, output accuracy, cooling, protections, bypass and site conditions on one sheet. Consultants and purchase teams can then compare every quote on the same basis. Ask each bidder to confirm each line in writing, with test documents.

Government departments, PSUs and universities often buy 200 kVA units through GeM (Government e-Marketplace) or open tenders. The same table works as a checklist for those bids.

200 kVA Servo Stabilizer Installation and Maintenance

To install a 200 kVA unit, have a qualified electrician fit it on the mainline after the meter or DG changeover. Size the input cables for the input current at your lowest voltage, about 391 A per phase at 295V phase to phase. Follow the CEA safety and electric supply regulations, and book a yearly service.

Place the unit on a firm, level plinth in a dry, ventilated room near the main LT panel

Check the oil level and phase sequence before first switch-on, and connect the neutral properly

Connect any UPS after the stabilizer, never before it

Use the bypass switch only during servicing; machines are unprotected in bypass

Terminate cables with crimped lugs and double compression glands; SG Power makes lugs for 6–300 sq mm conductors and brass glands up to 4C × 300 sq mm

Connect the body to the building's earthing system, using earthing rods or a chemical earth electrode, earthing clamps and an earth pit cover

Large 200 kVA runs often use single-core cables per phase; lay them in trefoil clamps on a cable tray to limit heating

Fit a surge protection device ahead of the stabilizer; forum users report fires and damaged stabilizers when an 11 kV line touched the low-voltage line. Protect the site in three layers: TruSafe earthing, Surge Protekt surge protection devices and Thunder Guard lightning protection (IEC 62305), with all earths bonded together
