Stable Safe High Current 100A to 20000A Primary Current Injection Test Set Kit for Circuit Breakers

Описание: In general, field testing and calibration of solid state trip units can be performed by either the primary current injection method or the secondary current injection method. Current injection testing is often associated with high current and high voltage power distribution systems in substations or large industrial installations. By injecting a predetermined current into the circuit breaker, it is possible to determine if the relay will trip at that current, and if so, how long the current needs to flow before tripping is initiated. Primary current injection testing is an invaluable aid in fault finding.

Weshine invented Primary Current Injection Test Set (high current generator), which integrates the advantages of similar products at home and abroad, adopts numerical control technology, and has strong anti-interference ability. The self-coupling voltage regulator and the converter made of high permeability iron core have the advantages of large output power, small size and light weight. Mainly used for primary busbar protection and transformation ratio of various current transformers and other testing projects, is widely used in electric power, railway, petrochemical, metallurgy and mining enterprises in scientific research, production and electrical test sites.
