Insulation Monitoring Relays: Key Devices for Safety Monitoring

Insulation monitoring relays are essential devices used to monitor the insulation status in electrical systems. The main function of these relays is to detect insulation faults that could lead to hazardous situations such as fires or electric shocks. Examples of such devices include products from Trafox, such as IM-04DCCT, IM-04PV, and IM-05DCCT.

How Insulation Monitoring Relays Work

Insulation monitoring relays operate by measuring the insulation resistance of the network using a generated signal and FFT analysis. Based on the obtained values, the insulation resistance is calculated. If the resistance drops below a set threshold value, the relay generates an alarm signal or disconnects the voltage.

IM-04DCCT Relay: Insulation Monitoring for Electric Vehicle Charging Stations

The IM-04DCCT relay is designed for monitoring insulation in electric vehicle charging stations. It supports voltage measurements up to 1000 V DC (1 kV) or 690 V AC. The insulation resistance measurement range is from 10 kΩ to 1 MΩ. The device offers alarm settings at various resistance and voltage levels and features communication via an RS485 interface. Additionally, this relay is equipped with an automatic calibration function to ensure accurate insulation measurements.

IM-04PV Relay: Insulation Monitoring for Photovoltaic Systems

The IM-04PV relay is intended for photovoltaic systems and allows monitoring of insulation in systems with voltages up to 1500 V DC. The device uses FFT analysis to precisely detect insulation faults and can operate in IT network configurations. The IM-04PV features alarm outputs that notify the user of the insulation status and also includes an automatic calibration function.

IM-05DCCT Relay: Solution for Insulation Monitoring in Electric Vehicles and DC Drives

The IM-05DCCT relay is designed for insulation monitoring in electric vehicles, charging stations, and DC drives. It supports input voltages up to 1 kV DC or 690 V AC and measures insulation resistance from 100 kΩ to 1 MΩ. The device allows setting alarms at various resistance and voltage levels and offers communication via RS485 or CANbus interfaces. It also supports High Side PWM communication.
