LV (Low Voltage), MV (Medium Voltage) and HV (High Voltage) switchgear testing services are very important in Bangladesh, as they help ensure the safety and reliability of the power system. Switchgear is an important electrical component that helps in controlling the voltage of the system, protecting the circuit and protecting it from outages. Through this testing service, switchgear components such as contactors, tripping mechanisms, insulation and other electrical parameters are tested. Various power service providers and technical institutions in Bangladesh provide this service, which helps in ensuring the proper functioning and safety of LV, MV, and HV switchgear. Through switchgear testing, any type of fault can be identified and repaired quickly, thereby ensuring uninterrupted supply to the power system and avoiding major accidents.
