Description
Overview
GAOTek E1 tester is a portable device specially designed and developed for field calibration of single phase, three phase active and reactive induction as well as electronic electric meters and other kinds of electrical instruments. It is widely used in electric power, metallurgy, chemical industry, tobacco, textile, railway, shipping, property and other industries. It provides a convenient solution for the power measurement department to perform meter error calibration on site without power cut or removing the electric meter and for the power inspection department to verify the illegal acts of stealing electricity. This meter is mainly used to calibrate the errors of electric energy meters, check whether the wiring of metering devices is correct, check the transformation ratio and polarity of current transformers used for metering, and measure the electric power quality of users (including voltage harmonics, current harmonics, total harmonic distortion, voltage balance, etc.
