This instrument is a fully automatic, multifunctional, digital, and intelligent instrument specially developed by our company for on-site testing. It has the characteristics of high precision, high stability, low power consumption, and easy use. It is possible to measure three-phase AC voltage, current, phase between voltage and current, phase between voltage and current, phase between voltage and current, frequency, phase sequence, active power, reactive power, apparent power, power factor, and current vector sum simultaneously without an open circuit in the tested circuit. This enables the identification of transformer wiring groups, inductive and capacitive circuits, testing of secondary circuits and bus differential protection systems, and reading of differential protection groupsTAThe phase relationship between them, checking the correctness of the wiring of the electricity meter, and repairing the line equipment provide a safe, accurate, and convenient new type of power instrument for electricity inspectors.

This instrument uses the latest materials to design and manufacture the shell mold, with a high insulation sheath. There are two specifications to choose from for its current clamp. The pointed small clamp is suitable for areas with dense wiring, while the circular large clamp is suitable for detecting thick wires and can meet the needs of different places.
