1、 Daily appearance and basic inspection (must be done before each use)Appearance integrity inspectionCheck whether the instrument casing, display screen, and operation buttons are damaged, cracked, or deformed; Check whether the insulation layer of the test line (including high-voltage output line

1、 Technical Status: Multimodal Fusion and Intelligent Upgrade1. Maturity and differentiation of mainstream detection technologiesUltra high frequency (UHF) technology: With its anti-interference advantage in the 300MHz-3GHz frequency band, it has become the preferred solution for high-voltage scen

The core purpose of conducting circuit breaker characteristic testing is to verify whether the circuit breaker can reliably operate in the event of power system faults or abnormalities, ensuring the safe and stable operation of the power system. This can be carried out from the following three key d

1、 Clearly define the test object and scenarioThe insulation characteristics and testing standards of different electrical equipment are different, and instruments need to be selected according to the type, voltage level, and usage environment of the tested equipment:Low voltage equipment (such as
