In conducting an inspection of a network or installation of electricity required set of gauges. The measuring device used to measure network parameters, such as current and voltage, active power, reactive power, electric energy consumption, insulation resistance and resistance earthing. Activity measuring electrical quantities are commonly referred to as measurements.
Define the measuring value of the measuring scale analog as shown in Figure 6.1. Figure 6.1 a. Limits of measurement used are: 25 DCV, 50 DCV and 100 DCV Figure 6.1 b. Limits of measurement used are: 5 A, 10 A, and 25 A

Gauges used in the measurement of electrical quantities, specially designed according to its function. The measuring device is:
– Volt meter for measuring electrical tegagan
– Ampere meter for measuring the electric current
– KW active power meter to measure
– Kvar meter to measure reactive power
– KWh meter for measuring electrical energy consumption
– Ohmmeter to measure the electrical resistance
– Megger or insulation tester to measure the insulation resistance
– Earth Tester to measure grounding prisoners.
