WebJan 1, 1996 · The test specimen then is discharged and the test is done again, this time at a higher voltage, say 2500V. If more than a 25% difference exists between the two IR readings, age deterioration or damaged insulation should be suspected. SIDEBAR: Basic Theory. An equivalent circuit for electrical insulation is shown in Fig. 5 below. The top ... WebA non-contact voltage tester is the safest way to make sure the power is off without touching any wires. Before you open an electrical box, you should: - cut off power to the outlet at the main electrical panel. - confirm you turned off the right circuit. This is where the non-contact voltage tester comes in handy.

WebOct 26, 2009 · You have an open neutral. Your digital multimeter is reading capacitively-coupled voltage on the disconnected neutral wire. This is to be expected. If you use an analog meter or a low-impedance digital meter, it will read 120 H-G, 0 H-N, and 0 N-G. If you measure resistance from N-G, it will read "infinite" instead of 0 like it's supposed to. WebHot-neutral is the load voltage. Voltage should read about 120 V (typically 115 V to 125 V). You measure exactly 118.5 V. Neutral ground is a voltage drop (also called IR drop) … A neutral wire breakage will cause an electric shock. Any device connected to the circuit will get high voltage and probably overheat. And this is very dangerous for your appliances and people in the house. The neutral wire takes all the heat from the incomplete circuit.
