YS Engineering Solution provides meticulous VCB (Vacuum Circuit Breaker) Testing and Service programs, which are essential for guaranteeing the safety and optimal performance of Medium Voltage (MV) and High Tension (HT) power systems. Their comprehensive service includes a detailed mechanical inspection for wear, lubrication, and adjustment of the operating mechanism. Crucially, they conduct rigorous Electrical diagnostic testing, including Contact Resistance Measurement to check the integrity of the main contacts and Insulation Resistance (IR) testing to assess the vacuum interrupter bottle's health. The most critical aspect is the Primary and Secondary Injection Testing of the associated protective relays, ensuring the VCB trips accurately and swiftly under fault conditions. This systematic testing and service regimen minimizes the risk of system failure and significantly extends the breaker's reliable operational life.
