60KV 2ma DC Cable Test System is designed and manufactured based on the latest China electric power industrial standard DL/T848.1-2004 “General Technical Specifications of DC High Voltage Generator”. It is mainly applicable for DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide arrester, transformers, and generators used in electric power departments, industry, and metallurgy and iron & steel enterprises.
Q&A：
What is the principle of a DC resistance tester?
During the measurement, the constant current is fed into the constant current from the I+ and I- test objects, and the current generates a corresponding voltage value on the measured object. This voltage value is taken back to the unit at the V+ and V- terminals, and after amplification, Directly display the result value of the tested product with four and a half LCD numbers.
