SAFETY CLEARANCES|BASIC INSULATION LEVEL|Sectional Clearance|EXTRA HIGH VOLTAGE SUBSTATION

Safety clearances in extra high voltage substation are very much important to maintain the basic insulation level of the system. If the system is designed without proper clearances there shall be insulation break down and flash over. A substation or a system faces several over voltage condition, due to lightning, due to switching or fault etc. These over voltages are capable enough to breakdown insulation and cause flash over.
