An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth.It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 kΩ (sample of IEC standard for medical applications).
A GCM or ground continuity monitor (also called a ground integrity monitor or ground continuity tester) is an electrical safety device that monitors the impedance to ground of a temporary electrical circuit and can provide indication (or protective trip) in the event impedance rises to an unsafe value. A GCM is either an external testing device ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

The gateway bridges U-UGS sensor field to the FCS network and relays motion alarm and image data. It's capable to be monitored locally by a soldier or remotely through a FCS network enabled modulevehicle. The intrusion node is a motion sensor that detects movement and is able to tell the difference between animal and human beings.
A ground conductor only carries significant current if there is a circuit fault that would otherwise energize exposed conductive parts and present a shock hazard. In that case, circuit protection devices may detect a fault to a grounded metal enclosure and automatically de-energize the circuit, or may provide a warning of a ground fault.
In electric power distribution networks, a fault indicator is a device which provides visual or remote indication of a fault on the electric power system. Also called a faulted circuit indicator (FCI), [1] the device is used in electric power distribution networks as a means of automatically detecting and identifying faults to reduce outage time.
The SM gathers the infrared image and transmits the data to the Display Control Module. Display Control Module (DCM) – A 10.4 inch, 640 × 480, flat panel active matrix liquid crystal display (AMLCD). The Display Control Module (DCM) is lightweight and is mounted on the inside of the vehicle on a swing up mount over the driver's position.
