Medium Voltage Transformers

Medium Voltage Transformers are a type of voltage transformer offered in 5 KV or higher applications, up to 36.5 KV. These units are vacuum cast using polyurethane resin and are rugged in design.

Medium Voltage Transformers offer CSA approval, and are typically installed in medium voltage switchgear.

Typical applications include medium voltage switchgear.

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.

Features:

• BIL up to 200 kV
• Vacuum cast using polyurethane resin

Applications:

• Medium voltage switchgear

Standards:

• Designed to meet C57.13

Approvals:

• CSA
