Results to be recorded on the bus duct record sheet. For example, a HiPot test verifies that the multiple conductive layers within a laminated bus bar are sufficiently insulated from one another at a specified voltage. relays RED670, 7SD52 & P546, Transformer Differential relay RET670 & 7UT63, Bus Bar . The commissioning process is a quality-focused process for enhancing the delivery of a project. This test is especially important for medium voltage, multilayer laminated bus bars, inverters, and any critical power conductor applications where electrical insulation is of paramount importance. A stability test should be done on the busbar relay same as the general differential relay. For simple bus bars, the ampacity tables are often enough, but parts with more complex geometries or multiple input/output connections, introduce variables that will skew performance from basic estimations. Insulation resistance will be carried out by IR tester at DC 1000 Volts to ensure that the system is free from short circuits and grounds. Three of the most important tests performed on the busbar are the High Potential or Hipot Test, Partial Discharge Test, and the Insulation resistance test, also known as a Megger Test. This checklist has been built to make it easier for inspectors to check transformers/motors, direct current (DC) battery system, and the operation and testing tools and equipment and perform efficient lightning protection system, busbar trunking system, circuitry checks, and more.
