High Current Generator is often called a current booster in the power industry



High Current Generator, often referred to as a current booster, current generator, or primary current injection device in the power industry, is one of the core devices in preventive tests of power systems. It is specifically used to generate adjustable high currents (ranging from tens of amperes to tens of thousands of amperes) to simulate the operating conditions of electrical equipment under rated current or short-circuit current. Combined with the DC resistance tester, insulation resistance tester, dielectric loss tester, test transformer, and high-altitude wiring clamp you previously inquired about, the high current generator completes the key link of "current source", mainly used for circuit breaker characteristic testing, CT ratio verification, busbar temperature rise tests, and complete relay protection transmission. 1. Core Functions and Working Principles Function: Convert ordinary power frequency power (220V/380V) into low voltage (usually <10V) and high current output through an autotransformer and a large-capacity step-up current transformer. Principle: Based on the transformer principle
