In the security protection camp of the power system, zinc oxide lightning arresters play a crucial role. Their unique working principle and significant advantages ensure the stable operation of electrical equipment.The working principle of zinc oxide lightning arrester is based on the nonlinear volt
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
