ST-9001D16 Three Phase Energy Meter Testing Equipm

Introduction

ST-9001D16 Three Phase Electric Energy Meter Testing Equipment is designed according to state standards, rules and requirement for whole automation testing equipment. It adopts Henan STAR Hi-tech Co. advanced designed large power three phases testing power source and reference meter. It could provide for manufacture, power supply departments, and metrology departments to test and calibrate electronic type or mechanic type three phase three wire, three-phase four-wire active energy meter sand reactive energy meters.

Main Function

Its operated by PC (or the equipment with keyboard)

The equipment adopts test by comparison method could operate by manual or animation complete test for under testing meter and auto print out testing results. It could test16 sets different meter constant meters simultaneously

The customer according to the requirement of rules any select current loading points fordifferent under testing meter to auto test

When manual test with reline testing points, phase with eight testing point frequency testing points same as the power supply, such testing points simplify testing work greatly

The equipment could test under testing meter by four quarter, the reactive standard is sine reactive standard

The equipment with high and low pulse output ports of reference meter and could reverse testDigital display output voltage, current, power, phase and frequency

Output voltage and current could any 2~21th harmonics. The harmonics could set in split phase or by voltage and current. Any phase output with multi-harmonics

With current ranges auto transfer function. The customer according to under testing meter rated current to select range within 0~120A

Output voltage and current soft on/off. Output voltage short circuit or output current open circuit auto protection and indicate the fault point

Output voltage by star connection, output current by floating point. (Three phase three wire voltage output by U connection)

Current inner CT active compensation with small size and high accuracySingle power source supplyIt adopts module structure with independent operation easy to calibration, maintenance and upgrade
