MGFL100 Battery Ground Fault Locator

The MGFL100 battery ground fault locator locates ground faults on ungrounded DC and AC systems, DC battery systems, and protected IT networks. It also alarms when the real fault is found, while automatically distinguishing between real fault current and reactive current drawn by stray system capacitance.

The MGFL100 measures the earth/ground fault resistance, the system capacitance, the real fault current, and the reactive leakage current. It also locates high impedance ground faults due to water ingress, as well as ground faults on systems with high leakage current. The MGFL makes locating the ground fault fast and easy by alarming when the circuit with a real ground fault is located. No complicated tuning out of noise or capacitance is required. Easily trace the fault with the lightweight transmitter and receiver. Set both password-protected voltage and current limits to ensure you never put too much current in your system.

The MGFL100 system can perform several fault-detection operations
