The PCLM (Pilot Core Loop Monitor – also known as an earth resistance monitor – ERM) measures the impedance of earth connections within Field Electrical Power Distribution Systems (FEPDS) and is designed for rough usage including air drop insertion (withstanding 1000G Shock) to operate in temperatures -40ºC to +80ºC and to withstand the bombardment of Neutron & Gamma rays in the event of a nuclear attack.
Installation involves fitting to a mobile generator and to each of the associated modular distribution modules.
