Description

The Polarity Checker quickly identifies transformer and motor winding polarity, ensures correct phase connections, prevents wiring errors, and provides reliable, portable, and easy-to-use operation for efficient field and maintenance testing.

• Used for polarity test in power plants, substations
• Polarity check of terminals and wiring connected to CTs and VTs
• Designed with Master-Slave units to automatically inject high-precision pulse current
• Adjustable amplitude and period to the primary side of CT
• Receive and analysis the waveform of induced pulse current at the secondary side simultaneously.
• Adopts special design of constant current output mode so that it is with high load capacity.
