Product Description HZ-3521A 3 Phase Energy Meter Calibrator Device Electricity Meter Calibration Equipment Product DescriptionI.OverviewHZ-3521A three-phase watt-hour meter field calibrator is specially designed for on-site inspection of high-voltage power grid metering devices and fault detection. The instrument USES high-precision internal transformer and clamp type transformer for sampling, so that operators can quickly, safely and reliably measure meter recording errors and wiring errors. It provides an effective basis for electric power system inspectors to check electric theft and leakage, find out the failure of metering device, measure correctly and recover electric quantity.HZ-3521A three-phase watt-hour meter field calibrator adopts the current popular ARM processor, 168M main frequency 128M memory expend 4G memory card. LCD adopts 7-inch hd color touch screen, combined with emwin display interface, which makes the instrument interface friendly and simple to operate, and can operate with full touch screen without keyboard. The instrument supports a file system that seamlessly connects to the computer.II.Functions and Features2.1 In the case of no power failure, without changing the wiring of the metering circuit, the error of the metering device is detected to determine whether the metering device is faulty.2.2 It can measure a variety of electrical parameters such as voltage, current, power, phase angle, power factor, frequency, etc., so as to accurately determine the fault of the measuring device circuit.2.3 can measure CT ratio error and phase angle (optional function).2.4 Display vector diagram of three-phase voltage and current, which can visually check the wiring error of the metering device.2.5 Current loops are measured using clamp-type transformers, allowing operators to make measurements quickly, easily, safely and reliably without opening the current loop.2.6 Can not change the wiring to detect the integrated error of the reactive energy meter.2.7 The instrument has waveform display and harmonic analysis function. The instrument can display the voltage and current waveforms of each channel at the same time or separately. The instrument can analyze the 1-32 harmonic content and harmonic values and draw a column chart.2.8 Built-in emwin operating system, 7-inch true color LCD display, no keyboard full touch operation, one screen can display a variety of electrical parameters.III.Input Characteristics3.1 Input characteristicsVoltage 2~450V automatic conversion limitClamp type current transformer measurement range: 0.1~5A (20A, 100A, 500A optional)Phase angle: 0~359.9oFrequency: 45 ~ 55Hz3.2 Accuracy: 0.053.3 Working temperature: -20~+503.4 working power: 80V~265VACMachine power consumption: ≤3VA3.5 volume: length: 280mm, width: 200mm, height: 75mm3.6 weight: 2.5kg3.7 insulationa.
