Research on Handover Test and Live Testing Technology of Surge Arresters Below 220 kV Class
Research on Handover Test and Live Testing Technology of Surge Arresters Below 220 kV Class
1. Overview of Surge Arrester Handover Test Technology1.1 Necessity of Handover TestThe handover test is a crucial step in ensuring the performance and safe operation of surge arresters within power systems. For power systems with voltage levels at 220 kV and below, surge arresters play a core role in protecting electrical equipment from damage caused by overvoltages and lightning strikes. However, during the process from the arrester leaving the factory to its actual operation after installatio

What Is a Voltage Class?Definition of Voltage Class:Voltage classes (or voltage levels) refer to a set of standardized rated voltages used in power systems and electrical equipment. A rated voltage is the nominal voltage at which equipment is designed to operate under normal conditions; essentially, a voltage class defines the intended working voltage range for a system or device.Analogy to Consumer Appliances:Household appliances (e.g., refrigerators, TVs) operate at a nominal voltage—typ

What is the reason for conducting five impulse tests before commissioning a transformer?
Verification of Insulation IntegrityWhen a new or overhauled transformer is energized under open-circuit (no-load) conditions, switching surges—caused by operations such as opening or closing the no-load transformer circuit—can generate overvoltages. These reach 4.0–4.5 times the phase voltage if the neutral point is isolated or earthed through a Petersen coil, and up to 3.0 times the phase voltage when the neutral is solidly grounded. The full-voltage, no-load impact test deli

Analysis of the Causes of Large - scale Failures of Surge Arresters in 10 kV Distribution Lines
1. IntroductionDuring power system operation, main equipment faces threats from internal and atmospheric overvoltages. Surge arresters, especially metal oxide arresters (MOAs) with excellent nonlinear volt - ampere characteristics, are key for protection due to their good performance, large current - carrying capacity, and strong pollution resistance. However, long - term exposure to power frequency voltages, along with component quality, manufacturing processes, and external environments, makes
