Megger MGFL100 – Battery Ground Fault Locator

• Locates ground faults on ungrounded DC systems and AC IT networks
• Measures fault resistance, fault current, leakage current, and system capacitance
• Distinguishes real faults from capacitive leakage currents automatically
• Provides audible and visual alarms when the true fault circuit is found
• Adjustable current and voltage limits help prevent system disruption
• Operates on systems up to 600 V and locates faults up to 400 kΩ

The Megger MGFL100 Battery Ground Fault Locator helps technicians track down ground faults quickly and with confidence. It locates faults on ungrounded DC battery systems as well as AC IT networks used in critical installations. The instrument directly measures fault resistance, leakage current, and system capacitance. This allows users to see the true condition of the circuit without complicated adjustments. It also separates real faults from harmless capacitive leakage currents, helping technicians avoid chasing misleading signals. When the instrument identifies the correct circuit, it triggers both visual and audible alarms for clear confirmation. The rugged transmitter and lightweight receiver make the system easy to carry and operate in the field. Adjustable current and voltage limits add control and help protect the system during testing.
