Description
Overview
GAOTek system frequency line tester is a kind of high-precision testing equipment for testing all kinds of high voltage transmission line parameters in the field or laboratory of power stations, substations, etc. The instrument is an integrated structure with a built-in variable frequency power module and variable frequency and adjustable voltage output power supply. the frequency can be changed to 45hz or 55hz. the digital filter technology is used to avoid the interference of the power frequency electric field to the test, which fundamentally solves the problem of accurate measurement under the interference of a strong electric field. at the same time, it is suitable for the situation where the generator is used for power supply detection after power failure.
