HYG-220 dual-clamp intelligent phase volt-ampere meter is a multi-functional intelligent instrument for field testing, which consists of a host, two current clamps and four test lines. The host computer uses 3.5 inch true color LCD screen, graphical menu interface display, the measured parameters are displayed on the same screen, at a glance. Current clamp integrated handle design, easy to operate, is very suitable for places with intensive wiring. The instrument can measure two AC voltage, current, voltage phase, current phase, voltage and current phase, frequency, active power, reactive power, apparent power, power factor and phasor diagram when the measured circuit is not open; distinguish transformer wiring group, inductive and capacitive circuit, test secondary circuit and bus differential protection system, and read out differential operation. To protect the phase relationship between CT of each group, check whether the connection of watt-hour meter is correct or not, and overhaul the circuit equipment, etc., to provide a safe, accurate and convenient intelligent instrument for power inspectors. It is suitable for electric power, petrochemical industry, metallurgy, railway, meteorology, industrial and mining enterprises, scientific research institutes, measurement departments, etc. Especially suitable for electric energy billing system and relay protection system.
The instrument is equipped with USB interface, which can store 99 sets of data, upload the stored data to the computer through system software, and realize reading, querying, saving, reporting and printing of historical data.
