Basic engineering acceptance requirementsAs the foundation of the line, it is necessary to ensure structural stability and precise parameters. The surface of the concrete foundation should be smooth and compact, without defects such as exposed reinforcement, honeycomb, cracking, etc. The qualified r
During the use of relay protection testers, various incorrect uses may occur due to non-standard operation, improper parameter settings, or neglect of safety requirements. This not only affects the accuracy of test results, but may also damage equipment or cause safety hazards, as follows:1. Imprope
The core working principle of the insulation oil withstand voltage tester is to simulate the electric field environment during the actual operation of power equipment. By applying a steadily increasing AC high voltage to the insulation oil sample until it undergoes breakdown discharge, the insulatio
1. Precautions for Preparation Before TestingIt is necessary to confirm the reliable grounding of the equipment, and the grounding resistance must meet the requirements (usually ≤ 4 Ω) to avoid the risk of electric shock during high-voltage testing.Check the appearance of the equipment, test the c
Insulation performance testThe core function of a lightning impulse generator is to conduct insulation impulse withstand voltage tests on high-voltage electrical equipment such as transformers, cables, insulators, etc. It assesses the insulation strength of these specimens under overvoltage by gener
