General Information

GDZT-1A Transformer Winding Impedance Tester is suitable for short circuit impedance measurement of 35kV main transformers. On-site and laboratory test are both ok.

Features

• LCD screen, data can be read clearly even in direct sunlight.
• Measurement data is accurate.
• Single phase measurement mode. When selecting transformer connection, each phase short circuit impedance can be obtained automatically after three times measurements.
• Voltage, current and power can be measured at the same time. The frequency of imposed power supply is also measured.
• With memory to storage data.
• Small size and light weight.
