In all electrical relays, the moving contacts are held in place by a continuous force, known as the controlling force. This force keeps the contacts in their normal positions and can be gravitational, spring.

High voltage relays are used in many technical devices that require voltages that go up to 10,000 V and currents up to 30 A. So, protection relays are mostly required in MV (medium voltage) and HV (high voltage panels) where it's combination with the breaker will prevent overcurrent (because a relay can just detect and give a signal, but cannot trip the circuit, which requires the mechanical action of breaker to do the. Long term cost reduction (TCO) for trainings and maintenance by reduce variety of relays A fast and selective arc fault mitigation for air-insulated LV & MV switchgear and Relion protection and control relays and sensor. Many industries use voltage protection relay systems, especially those in high-voltage.

Industrial electrical relay panels handle high voltages and large fault currents. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. That's why choosing the right protection infrastructure, including reliable Control & Relay Panels, is one of the most critical decisions any plant manager or electrical engineer will make. Traditional relay protection often falls ineffective in power-electronics dominated grids, increasing the risk of mis-operation or operation failure and compromising grid stability.
