Interconnect Resonance

Product Introduction

Transformer,GISSystemsSF6SwitchesCT/PTInsulators, busbars, cables, and sleeves, among other capacitive equipment, are common primary electrical equipment found in substation facilities. According to220VAnd the following requirements for the test procedures of voltage withstand for the electrical equipment in the substation./DC resistance test equipment must meet both high-voltage, low-current test conditions and low-voltage, high-current test conditions, requiring a wide applicability range. It adopts the principle of series resonance and is controlled by a variable-frequency power supply control box.(Console)The main equipment consists of step-up transformers, reactors, and capacitor voltage dividers. On the capacitor voltage divider, by connecting a rectifier silicon stack and a microampere meter, a DC withstand voltage test can be completed. Due to the system's excellent filtering characteristics after resonance, the produced DC voltage is superior to that of a standard test transformer rectifier. It is an ideal withstand voltage equipment for high-voltage test departments at the county, city, and provincial levels, as well as for power installation, maintenance, and testing engineering units.
