| Transformers & Variacs | Are wound with electrolyte grade copper of 99.9% purity, Low loss CRGO Lamination is used to increased over all efficiency, this reduced Energy losses and hence Saves Electricity. |
| Earthing | Provided through two bolts & Nuts |
| WINDINGS | Coils are wound with paper covered electrolytic grade copper strip or synthetic enamelled copper conductors. Cooling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength. |
| TANK AND PAINT | The tank of Servo Voltage Stabilizer is made of M.S. steel sheets. All the external surfaces are given a primary coat of epoxy and finishing coat of epoxy paint for better life and leak proof. All our tanks are power coated for shelf life of 20 – 25 years. |
| OIL | Oil tested for resistivity, dielectric and acidic characteristic conforming to IS 335, transformer oil is an important part of Servo Voltage Stabilizer which provides cooling to the critical components housed inside the tank, so we always make sure that the quality of the transformer oil is far better. |
| DUTY CYCLE | Conventional type stabilizers are suitable for 50-60% load on continuous duty cycle. Servo Voltage Stabilizers are heavy duty and industries friendly and are suitable for 99% load continuous duty cycle. |
| Optional Feature (Which can be incorporated for extra cost) |
: High and low Voltage cut off system : Over Load and Short Circuit Protection : Phase sequence change protection : Change over switch to by pass the Stabilizer and use main voltage directly : Single Phase Prevention system (in three phases) shuts down the stabilizer in case any of phases fails Surge and RF Suppression System. : Power factor correction system to reduce power consumption for saving power. : Ammeter with CT to monitor the connected load. : Earth Protection, Temperature Gauge and Isolation Transformer. |
