DJC-204A Transformer Oil Dielectric Loss Tester

Application:

Transformer oil dielectric loss tester is a high precision instrument for dielectric loss angle and volume resistivity of insulating oil and other liquid dielectric.

Features:

◆Adopts digital technology, intelligent automation measurement.

◆Equips with 240x180 liquid crystal display screen.

◆Test results can be printed, the operator does not need professional training to be able to skillfully operate.

◆Digital control the inverter and sampling circuit, output voltage is continuously adjustable.

◆With various protection measures for input voltage fluctuation, output short circuit, over-voltage, over-current, temperature ect. ensure the safety and reliability of the instrument.
