Megger MGFL100 Battery Ground Fault Locator
Techno Master offer you Megger MGFL100 Battery Ground Fault Locator in Egypt.
A specialized instrument that locates ground faults on ungrounded DC and AC systems, DC battery systems and protected IT networks without shutting them down — alarming when the real fault is found and automatically distinguishing real fault current from reactive current drawn by stray capacitance.

Testing capabilities
- Locates ground faults without shutting the system down — ideal for critical systems where uninterrupted power is essential
- Alarms when the real fault is identified — no tuning out of noise or capacitance required
- Direct measurement of fault resistance (up to 400 kΩ), stray capacitance, fault current and leakage current
- Identifies which side of the battery string has the ground fault — no need for a DMM
- High-impedance ground faults due to water ingress and faults on systems with high leakage current
- Password-protected voltage and current limits prevent over-current into the system
- Fused transmitter leads protect against arc flash on DC systems
- 5.12 Hz tracing signal for operation on noisy systems; will not trip DC breakers
- Optional IT filter enables fault locating on IT grounded AC systems up to 600 V AC
- Lightweight transmitter and receiver for easy tracing; powered off AC or internal battery
