Resistive loads These are the easiest types of loads to test. Project commissioning is the process of assuring that all systems and components of a building or industrial plant are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client. Check the conductor to ground with the low impedance option and check for the presence of voltage with the proximity meter while doing so. Pay particular attention to these measurements, because even though the measured voltage may not be more than 10% higher than the equipment rating, this lowers the full load amperage rating of the motor. For example, the owner preferred to have two sources of power to this facility, but only one medium-voltage source was available in the area. If not done properly, small issues can become much bigger issues if not addressed during pre-commissioning. Before performing any insulation test, you should always consult the component manufacturer for detailed testing instructions and voltage limitations. Refrigeration and electrical circuit diagrams.
