Question about this product?
Features
- Locates ground faults on ungrounded DC and AC systems, DC battery systems, and protected IT networks without system shutdown
- Automatically distinguishes between real fault current and reactive leakage current drawn by stray system capacitance
- Issues an audible and visual alarm when a real ground fault is found, eliminating the need for complicated tuning
- Locates high-impedance ground faults up to 400 kOhm, including those caused by water ingress
- Directly measures fault resistance, system capacitance, real fault current, and reactive leakage current
- Identifies which side of the battery string has the ground fault, removing the need for a DMM
- Password-protected adjustable voltage and current limits prevent excessive current injection into the system
- Transmitter can be powered from AC mains or internal rechargeable battery for full portability — approximately 4 hours battery life
- Operates on systems up to 600V
- Fused test leads provide arc-flash safety
- Suitable for substations, railways, hospitals, maritime, and industrial facilities
- CAT IV 600V safety rating to IEC 61010
