A1151 oil volume resistivity tester Introduction
A1151 oil volume resistivity tester is based on DL421.91 "Insulating Oil Volume Resistivity Measurement Method" based on the electric power industry standard, and a new type of special resistivity measurement instrument developed based on the principle of active bridge. It has the advantages of simple structure, good linearity, high sensitivity, stable test results, and safe operation. Its performance is much higher than the ordinary voltage and current method. The instrument consists of a parameter measurement system and an oil cup heating and temperature control system, with automatic timing and LCD display functions. It can measure the volume resistivity of insulating oil. Technical Parameters
