Cooling System for HV Arc Flash Suit Wearer

High Voltage switching is very dangerous and has caused many fatalities or damage to equipment. Two of the most common sources of HV switchgear accidents are a lack of following safety protocols and an insufficient understanding of the HV electrical systems; just as car drivers can avoid accidents with proper understanding of driving, so can HV personnel. But because HV switching accidents do happen, the personnel are required to wear arc flash suits. But the experience of the personnel in equatorial Malaysia is that they sweat profusely even after a minute of wearing such suits. To solve this problem a robust car air conditioner system was driven with a 3Φ, 2 HP induction motor and cool air is sent via a 6 m flexible pipe to go from the bottom of the arc flash suit to the chest level. One such system should be permanently placed in each substation.
