High & Medium Voltage

Routine Test Requirements in HV CBs Routine tests are essential in the manufacturing process of high voltage (HV) circuit breakers. These tests are conducted on each unit before delivery to ensure the quality, reliability, and performance of the circuit breakers. Routine tests verify the...

Gas Circuit Breakers (GCB) are critical components in electrical switchboards for high voltage electrical systems. GCB are renowned for their ability to efficiently interrupt fault currents and protect power grids. These breakers utilize sulfur hexafluoride (SF6) gas, a potent insulating and arc-quenching medium. The...

High voltage (HV) circuit breakers are essential components of switchboards in electrical power systems, designed to interrupt fault currents and protect electrical circuits from damage and for control switching purposes. They are used in systems where the voltage levels are typically above 72.5 kV,...

As the complexity of grid and integration requirements rises, High Voltage (HV) switchboards, control panels, and switchgear need to be expertly made to meet safety and performance criteria for demanding applications. “Switchboard and switchgear requirements differ from State to State, so it’s important that...

Part 1: Standards Followed in Designing High Voltage Circuit Breakers High voltage (HV) circuit breakers are essential for ensuring the stability and safety of electrical power systems. Designing and manufacturing these devices require adherence to stringent international standards to ensure their reliability and performance...

Surge diverters effectively protect against voltage surges resulting from the operation of medium and high voltage power distribution switchgear. Unlike lightning strikes, which are high-energy events, these transient surges typically arise from operational anomalies or rapid changes within the electrical system. Applications The range...

Clean air plays an important role for a sustainable future but high-performance switchgear relies on sulfur hexafluoride (SF6), a potent greenhouse gas with a global warming potential 23,500 times greater than carbon dioxide (CO₂). Climate change has been of extreme importance and there is...
