  • Page 57: Spd (1674 Fc)

    Multifunction Tester Measurements SPD (1674 FC) Surge Protection Devices (SPDs) or surge arresters are used to absorb high voltage peaks that surpass any nominal value voltages and potentially harm the installed equipment. At normal voltage levels, the SPDs make up a high impedance, are non-conductive, but at some voltage level (greater than nominal voltage levels) the Tester starts a current draw to make a low impedance.

  • Page 58: Imd

    1672/1673 FC/1674 FC Users Manual Insulation monitoring devices (IMD) continuously monitor the insulation resistance of IT systems (unearthed systems that are meant to have no built-in ground reference) and issue an alarm if the value falls below a response value. To make a measurement, the Tester has to be connected between the IT system and the (local) protective earth conductor (PE).
