Education: Dear fellows, This is the most comprehensive online training of MV switchgear. Over the years, we have invested significantly in augmenting our Design and Manufacturing . 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. Generally, the HiPot test is run at an exaggerated voltage level of 2X the operating voltage plus 1,000 volts to ensure safety and performance even in extreme scenarios. 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. Through the guidelines contained herein so as to ensure that the job execution complies with the project requirements Read Full Method Statement Join for Latest Articles In the first article of a series that will explore the commissioning process in more detail, we answer the often-asked question What is Commissioning and Testing? Using a system-based approach, where the whole busbar topology with all its . jumper cables, terminals and various devices by using an infrared scanner. Deployment of a competent personnel for the task. The words controlled and coordinated are key here. Ensure all joint covers are firmly secured. All Rights Reserved.

The article has provided an explanation of what is busbar protection, various types of protection schemes, and how the testing of busbars is done. Important: Ensure equipment is disconnected from any possible source of electrical supply; disconnect I draw out ACB I MCCB feeder; switch off all tap off units, disconnect neutral and earth cables.
