]]> Thunderstruck Motors Ground Fault Monitor GFM 2.0 measures the isolation between an
electrical system ground and a separate High Voltage (HV) isolated system. It is designed for use
in a wide range of Electric Vehicle (EV) systems and is highly configurable.
The GFM measures isolation between the two systems by applying a known resistance between
the low voltage ground and both HV buses (positive and negative) in an alternating sequence,
then measuring the very small resulting current. The advanced measurement algorithm allows
the GFM to make accurate measurements in rapidly changing and noisy systems. The isolation
measurement is reported in several forms: fault resistance, ohms/volt, and average fault
location. Symmetrical, asymmetrical, intermittent, and capacitive faults can all be measured by
the system.
The GFM intelligently uses measured isolation metrics to evaluate two configurable fault
thresholds (warning and fault). The GFM has two outputs that may be configured to represent
these faults, allowing an operator to create warning lights and system interlocks. The present
state of the fault, the number of occurrences, and the history of each fault is available to the
user. These fault conditions, as well as all measurements, are available over CAN bus using sID
(standard ID) and eID (extended ID) based protocols
