HZ-3521A Portable Handheld Three Phase Electric Energy Meter Field Calibrator
I. Functions and Features
1 .Error Detection Without Power Interruption
Without changing the wiring of the metering circuit, the instrument can detect the error of the metering device to determine whether the device is faulty, even in the absence of a power failure.
2 .Comprehensive Electrical Parameter Measurement
The instrument can measure a wide range of electrical parameters, including voltage, current, power, phase angle, power factor, frequency, and more, allowing for accurate diagnosis of faults in the metering device circuit.
3 .CT Ratio and Phase Angle Measurement (Optional)
It can measure the CT ratio error and phase angle, offering an optional function for more detailed analysis.
4 .Three-Phase Voltage and Current Vector Diagram
The instrument displays the vector diagram for three-phase voltage and current, making it easy to visually detect any wiring errors in the metering device.
5 .Clamp-Type Transformer for Current Loop Measurement
Current loops are measured using clamp-type transformers, enabling operators to perform measurements quickly, easily, safely, and reliably without opening the current loop.
6. Integrated Error Detection of Reactive Energy Meters
The instrument can detect the integrated error of a reactive energy meter without requiring any changes to the wiring.
7 .Waveform Display and Harmonic Analysis
The instrument features a waveform display and harmonic analysis function. It can display voltage and current waveforms for each channel either simultaneously or separately. Additionally, it can analyze harmonic content from the 1st to the 32nd harmonic, display harmonic values, and generate a bar chart for visual representation.
8. Advanced User Interface
Equipped with the built-in emWin operating system, the instrument features a 7-inch true color LCD display with full touch operation, eliminating the need for a keyboard. The display can show multiple electrical parameters on a single screen for easy monitoring.
