GE 760X90G3 Voltage Transformer

This voltage transformer steps down high primary voltages for metering applications. It provides isolated secondary signals to protection relays and instruments. You will install this unit inside switchgear or motor control centers.

Key Technical Specifications

The 760X90G3 accepts primary voltages up to 7200V AC. Its secondary output delivers 120V AC at 200VA maximum. The transformer also features a precision core for 0.3% accuracy class.

Hardware Architecture and Magnetic Core

The 760X90G3 uses a grain-oriented silicon steel core for high efficiency. Two separate secondary windings provide versatility for metering or relay applications. The core reduces hysteresis losses through precision lamination stacking. Copper enameled wire forms both primary and secondary windings.

Interface and Connectivity

Two primary bushings accept high voltage connections from the incoming line. Four secondary screw terminals provide access to two isolated 120V windings. Each secondary winding includes a grounding terminal for safety. The transformer also features a core ground connection point.

Practical Installation Notes

Mount this transformer on a flat surface inside the metal-clad switchgear. The 760X90G3 requires adequate clearance between primary terminals. Always connect the secondary windings to a suitable burden only. Never leave secondary terminals open while applying primary voltage.
