Product Detail

Product Tags

GDYT-350kVA/70kV PD free Resonant Test System is composed of PD free variable frequency power supply, HV measuring box, excitation transformer, isolation transformer, Resonant reactor, and capacitive voltage divider.
This test system does not have the problem of excessive starting current. Using a smaller capacity power supply can complete a test equivalent to 30 to 60 times of the power supply, which greatly alleviates the problem of insufficient capacity of the field test power supply.

Features

Safety and reliable. It has many functions, including discharge and breakdown protection, over-voltage and over-current setting protection, test power off protection, zero protection, over-heat protection etc. When any protection happened, the system will immediately cut off output and power, to ensure the safety of operators, test system and test object.
Simple operation and easy wiring.
320*240 LCD display, display output voltage, output current, frequency, environmental temperature, output waveform, date, timing etc.
Automatic searching resonant frequency, automatic frequency setting.
Test voltage and time can be set.
Output sine wave distortion rate of HV circuit is lower than 1%, which is no damage to test object.
Use indoor or outdoor. With hooks, suitable for hoisting on-site.
