1. Characteristics
Three-phase digital phase voltammeter, also called multi-functional three-phase digital phase voltammeter, is specially designed for on-site measurement of voltage, current, power, power factor, frequency and phase. High-quality, multi-functional, high-precision, intelligent, portable and handheld measuring instrument. It is widely used in departments such as electric energy measurement, electricity inspection, electric power inspection, meter installation and connection and relay protection, differential detection, start-up test, industrial and mining enterprises, scientific research institutions and other departments. Instrument testing is accurate, fast, simple, stable and reliable.
In addition to directly measuring AC voltage values, AC current values, the phase between voltages, between currents, and between voltage and current, and power frequency, the three-phase digital phase voltammeter also has other measurement and judgment functions for inductance. Determine the current and capacitive circuits, check the transformer wiring group, and check whether the electric energy meter is connected correctly. It is an ideal instrument to grasp the power usage and conduct secondary circuit inspection.
The three-phase digital phase voltammeter is composed of a host, a current clamp, and a test line. It simultaneously stores a group of data and has the function of static data storage. It has the functions of reading, checking, saving, reporting, printing and other historical data.
