ZGF-S series is the equipment for testing DC voltage and DC leakage current of water-cooled generator in the situation of water through, which completely overcome the problems of long blow water time, bottom water hard to dry, easy to cause arcing within the coil. The device is light, has simple wiring, and is easy to read. Polarization compensation voltage is output directly by the case.

1. Electronic control and tune, easy to operate.

2. The date of voltage and current are recorded in the panel, reading without conversion.

3. One-minute timing and tip function.

4. Perfect over-voltage and over-current protection function inside, also zinc oxide over-voltage protection outside, which ensure the safety of the generator.

5. Portable design, suitable for on-site testing.

6. Four parts separated: control unit, Intermediate Frequency Transformer, doubler, and accessories, all packed with special shockproof aluminum alloy cabinet, easy to move.
