Three Phase Voltage Transformers

Three Phase Voltage Transformers are a 3 Phase type of voltage transformer offered in 600 v class. These voltage transformers are for applications with 100% of rated primary voltages designed for line to line operation but may also be used in a line to neutral or line to ground configuration at 58% of rated voltage.

Three Phase Voltage Transformers offer a robust design, with some models offer built in Fuse protection. These units 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.

Features:

• 600V Class
• Designed for either Line-Line or Line-Neutral operation

Applications:

• Metering
• Protection

Standards:

• CSA
• UL
