The multi-functional power consumption tester is a comprehensive detection instrument that integrates various power consumption inspection functions such as the comprehensive error of the metering device, the error measurement of the electric energy meter, and the transformation ratio test of the high and low voltage current transformers below 35KV; it can freeze the power meter It can read events such as power consumption, load curve, loss of voltage and current, programming and cover opening records. It has functions such as analysis of wrong wiring of electric energy meters and calculation of electric quantity recovery. one.
2. Main functions:
● The overall (comprehensive) error measurement of the low-voltage metering device can measure the comprehensive error of the metering device composed of current transformers and meters.
● Energy meter error calibration, which can calibrate the errors of various mechanical and electronic energy meters.
● Visually display the wiring diagram, identify 192 kinds of three-phase three-wire wiring and 2304 wrong wirings of three-phase four-wire.
● Read events such as power meter frozen electricity, load curve, voltage loss and current loss, programming and cover opening records.
● Can superimpose various errors such as electric energy meter wiring errors, undervoltage events, voltage loss events, overvoltage events, phase failure events, reverse phase sequence events, unbalance events, current loss events, overcurrent events, and current interruption events Supplementary calculations allow employees of power supply stations to accurately deal with measurement errors.
● It can measure the current amplitude of high and low voltage lines up to 35KV.
● Apparent power calculation.
● It can measure the transformation ratio, polarity and phase-to-phase correspondence of 35KV and below high and low voltage current transformers, and check the nameplates of current transformers.
● Standard 20A clamp, optional 100A, 500A, 1000A clamp or 0-600A flexible clamp meter, with a low-voltage retractable operating insulating rod.
● The U disk stores the field data and the measurement data of 1000 meters, which is convenient for subsequent analysis.
● The closed long U-shaped clamp design improves the accuracy compared with the open-ended design, and the width of the measured object can reach 50mm.
● Equipped with a telescopic insulation rod, it is easy to carry.
● There are two power supply modes of lithium battery and test circuit, and the wide working power supply is AC 50V～400V.
● With RS485, RS232, far infrared, USB, Bluetooth, WIFI and other communication interfaces.
● It can be operated by handwriting on touch screen, hand-held design, and can also be connected to PDA for operation.
