DC INSULATION RELAY
Description
DC Insulation relay is a device used in electrical systems to monitor and ensure insulation integrity in DC circuits, such as those in substations, electric traction system of trains or trams, or electronic devices powered by DC energy.
DC Insulation relay is essential for monitoring insulation degradation in DC circuits, preventing equipment damage, reducing electrical leakage risks, and improving safety in direct current systems.
Features
Detecting current leakage
- Monitors the insulation resistance of the DC circuit to ensure it is at a safe level.
- Detects leakage current from wires or equipment to the ground or structure.
Preventing equipment damage
- Insulation degradation can lead to short circuits or electrical faults. The relay helps prevent such damage.
Enhancing system safety
- Alerts operators to potential issues in advance, allowing them to resolve problems before critical failures occur.
Protecting personnel
- By detecting insulation problems, the relay reduces the risk of electrical leakage that could harm personnel.
