Revenue Grade Voltage Transformers

Revenue Grade Voltage Transformers are a LV(Low Voltage) 600V Class type of voltage transformer. This type is offered in the Model 475 series which is approved for Revenue Metering by Industry Canada (ratios 69.3-120v, 120-120v, 208-120v, 240-120v, 277-120v, 288-120v, 300-120v, 346-120v, 400-120v, 480-120v, 600-120v)

Revenue Grade Voltage Transformers are available un-fused or with fusing, and have CSA approval.

Typical applications include metering and protection.

Voltage transformers (VT), also called potential transformers (PT), are a parallel-connected type of instrument transformer. The units are designed to present a negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to enable accurate secondary connected metering. Units have high efficiency for high frequency ranges.

Advantages of Voltage Transformers are the units enable an ordinary voltmeter to measure high voltages. Also, the units offer protection by having electrical isolation between the voltmeter and the high voltage line. Units have easy mounting and wiring setup.
