A Voltage Monitoring Relay continuously checks the voltage levels in electrical systems to detect overvoltage, undervoltage, or phase failures. It helps protect sensitive equipment by triggering alarms or disconnecting loads when voltage deviates from safe limits, ensuring system stability and safety.

A Current Monitoring Relay tracks the flow of current in electrical circuits to identify overloads, underloads, or phase imbalances. It ensures operational efficiency and protects motors, pumps, and other equipment from damage due to abnormal current conditions.

An Earth Leakage Relay detects leakage currents flowing to ground, indicating potential insulation failures or faults. It enhances electrical safety by providing early warnings or tripping circuits to prevent electric shocks, fire hazards, and equipment damage in residential, commercial, and industrial setups.
