The didactics case C.A 6710 can be used in training for standard-conform measuring at electrical systems. The international standards IEC 60364, NF C 15-100, VDE 100, IEE 16th, OeVE EN-1, CEI 64-8, NIN/NIV, RBT MIE, etc., have exact specifications to be observed to ensure that an electrical system functions correctly and that there are no dangers when operating it. The simulation allows complete and correct understanding of electrical systems (various earthing schemes, measurement of all electrical sizes, installation errors). This case is undoubtedly the most efficient and safest tool for training electricians as well as craftsmen, fitters, service technicians and engineers with regard to the application in practice. This case is also extremely useful when using various measuring devices. With the case C.A 6710 TT-, TN- and IT-networks with neutral conductor can be simulated and earthing-, loop- (phase/earth and phase/neutral conductor), insulation- and resistance measurements as well as continuity tests can be made. It includes various FI circuit breakers to test residual currents, interruptions in the phase, grounding or the neutral conductor and the reverse polarity of phase and grounding or neutral conductor.This text is machine translated.
