The Fluke 1650 Series instruments can also measure the earth resistance component of the total loop resistance, and line impedance (source impedance between line and neutral, or the line-to-line impedance in 3-phase systems) and calculate the prospective short circuit (PSC) current which could flow when there is a short circuit between line and neutral. The control panel markings are available in five languages (English, French, German, Italian and Spanish), and with universally recognised graphical symbols. It is therefore important to have suitable test tools for carrying out the stringent tests imposed by the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardisation (CENELEC). The testers ensure that fixed wiring is safe and correctly installed to meet relevant local standards and safety requirements. One auxiliary electrode is placed at a set distance from the earth electrode, and the other at 62% of the distance between the two in a straight line. Since these electrical conduits are not much stronger as compared … Residual current operated devices (RCDs) are often fitted for additional protection where they detect currents flowing to earth that are too small to trigger over-current operated protective devices or to blow fuses, but would still be sufficient to cause a dangerous shock or generate enough heat to start a fire.
