According to the new "Regulations for Handover and Preventive Tests of Power Equipment", the test current for measuring the conductive circuit resistance of various switchgear shall not be less than100A. To this end, our factory has designed and developed a new generation of intelligent loop resistance tester products according to the new regulations. This product is suitable for testing the contact resistance of main contacts of high and low voltage switches, and the DC resistance of high and low voltage cable lines.It adopts100A constant current output. The maximum output voltage reaches10V, allowing the use of thin test leads, which greatly reduces the labor intensity of field test personnel. The entire test process is automatically controlled by a single-chip microcomputer, with high precision, good repeatability, simple operation, LCD display of test data, and result printing. Suitable for different working environments.
