Handheld Three-Phase Capacitance Inductance Tester

      MOEORW-WCL31 Handheld Three-Phase Capacitance Inductance Tester is a portable electrical parameter measuring instrument designed specifically for power operation and maintenance personnel. Its core functions include three-phase/single-phase capacitance, inductance and resistance measurement, with inter-frequency interference suppression and non-disconnection testing capabilities. It can effectively solve industry pain points such as strong on-site interference, capacitor damage caused by frequent switching, troublesome wire disconnection for testing, and difficulty in data retention. It is widely used in reactive power compensation equipment testing in distribution networks, on-site testing in substations, operation and maintenance inspection of power equipment, and simple current quality analysis.

Reactive power compensation equipment testing in distribution networks: Used for regular inspection of capacitor banks and reactors in distribution networks to detect equipment defects in advance and avoid fault expansion caused by switching impact.

On-site live testing in substations: It can complete the measurement of three-phase capacitor banks without disconnecting the wiring, adapting to strong electromagnetic interference environments such as substations and distribution rooms.

Three-phase/single-phase electrical component testing: Supports three-phase Y/△/YN/Ⅲ type wiring samples, and can accurately measure single-phase capacitance, inductance, resistance and current parameters.

Current quality analysis: It can separately detect the fundamental frequency, total harmonic distortion and harmonic content of the current to complete simple power quality analysis.

Power equipment operation and maintenance archiving: Supports data storage, export and printing, meeting the needs of substation equipment operation and maintenance and test data retention.
