Trainer System: The Trainer should be provided with provision for practical training  on the aspects of electrical  installation, safety practices,  and measuring methods and  training for simulation of measurements on electrical  installations, fault simulations  pertaining to electric installation, demonstration of  actual measurements, along  with training aspects of electrical installations and . measuring instruments usage  mounted with real industrial  components onto a portable  tabletop system. The front panel should provides clear  depictions of the Electrical  Installation Safety System  such as for aspects of lightning protection, grounding, insulation resistance, 1 phase and 3 phase circuits, and the  test of leakage currents with  loads for the circuits, for both 1  phase and 3 phase. Working Principle and Measurement of AC Voltage of  Single Phase, Three Phase  Three Wire and Three hase Four Wire, Working Principle  and Measurement of DC Voltage and Battery Voltage.  R.S.T Phase Rotation Test,  Live (HOT) Line, Wiring continuity, Four, Three and 
Two Earth Resistance Measurement, Erath Voltage Measurement and Earth  Voltage Effect when Measuring Earth Resistance,  Insulation Resistance Measurement, Load current Measurement, Earth leakage  Circuit Breaker Test and Leakage Current Measurement, Fault Simulation and Troubleshooting, Insulation  Resistance Tester, 4-wire Earth Resistance Tester,  Digital Clamp Meter with leakage current measurement  function.
