200KV/3mA high-precision DC high voltage generator

Company Profile:

Our company mainly engages in testing transformers, oil filters, vacuum testers, cable fault testers, dielectric loss testers, fully automatic ratio testers, insulation oil dielectric strength testers, zinc oxide lightning arrester testers, high-voltage switch mechanical characteristic testers, transformer on load switch testers, fully automatic capacitance and inductance testers, transformer characteristic comprehensive testers, grounding resistance testers, microcomputer relay protection testers, insulation shoe [glove] withstand voltage testers, circuit resistance testers, DC resistance testers, insulation resistance testers, variable frequency series resonance testing devices and other testing instrument products.

For small capacitor test samples such as zinc oxide lightning arresters, magnetic blow lightning arresters, etc., first roughly adjust them to the required voltage (current) Read the voltage (current) value from the digital display. When measuring the 75% VDC-1mA of zinc oxide lightning arrester, the voltage value should be stopped when the current reaches 1mA (at this time, the voltage and current values can be recorded), and then the yellow button should be pressed to reduce the voltage to 75% of its original value and maintain this state. At this time, the microampere meter value and voltage value can be read. After the measurement is completed, the voltage regulating potentiometer returns to the zero position counterclockwise, press the green button, and press the red button when it needs to boost again.

Usage conditions:
