R & D
Carries electrical energy from primary to secondary distribution circuit.
Commercial, residential and light industry have own set of voltage requirements.
Manufacturing unit is facilitated with individual testing equipment’s like:
High Voltage Test Set (300kV)
Oil Test Kit (100kV)
Motor Alternator Set for DVD Test
Three Phases Variac and Single Phases Variac
Pressure Test Set
Manufactured and tested as per IS: 2026, IS: 1180, IEC 60076
Winding design and insulation to tolerate thermal and short circuit stresses
Overload capacity maintained as per IS: 6600 and specific requirements
Superior quality examination of diverse grades and designed according to Customer’s No Load Loss specification
On-Load Tap Changer
Transformer’s fitted with OLTC with different tapings on HV windings to suit client requirement or grid voltage conditions at customers site
For automatic voltage monitoring, OLTC is supplied with remote Tap Changing Cubicle (RTCC) Panel and Automatic Voltage Regulator (AVR) (optional)
Copper used for winding
Spiral low voltage winding with paper insulated rectangular conductors
Crossover HV coils with paper cover & SE copper wire Disc winding with rectangular copper strips (some cases multiple Disc)
To withstand temperature rise rigid type of transformer tank with attached cooling fins is required for extensive cooling area.
Corrugated type transformer tank for better cooling and space economy
Oil, conforming to IS: 60296, is filled in through streamline filter for moisture and gas removal
The windings are warmed in a hot air chamber to get high IR values
Some of the accessories are:
Dial Type thermometer
Winding Temperature Indicator
Pressure Relive Valve
Magnetic Oil Level Gauge
Dry Type Transformer..
Three Phase Oil Cooled servo stabilizers..
Variable Auto Transformer..
ISO 9001:2008 CERTIFIED
Power Saver, Isolation Transformer
Variable - Auto Transformer & Variac
