If a stick is not available, then insulate yourself by standing on a dry wooden board, thick … [Read more...] about How to Rescue a Person from Electric Shock?
What is a switching station? A switching station is a substation that does not contain power transformers and therefore does not change system voltage from one level to another. Switching stations usually operate at sub-transmission or transmission voltage levels. Depending on system voltage, the equipment types and characteristics used in switching stations are … [Read more...] about What is Switching Station? | Working and Layout
