ADVANCED CONCEPTS IN high RESISTANCE GROUNDING Copyright Material IEEE Paper No. PCIC-2012-25 Ajit Bapat Life Senior Member, IEEE Power Solutions 257 Burbank Drive North York, On M2K 2S4 Canada Dr. Robert Hanna Fellow , IEEE RPM Engineering 2816 Hammond Road Mississauga, On, L5K 2R1 Canada Sergio Panetta, Senior Member, IEEE I-Gard Corp. 1-7615 Kimbel St Mississauga, On L5S 1A8 Canada 1 Abstract - RESISTANCE grounding is relatively simple and easy to apply in radial distribution systems at Low Voltage. When high RESISTANCE grounding is applied, using one Neutral Grounding Resistor at the supply transformer, an alarm system to detect and indicate the ground fault is then required by the installation codes.
2 . 1. Arc Flash and Blast hazard for a line to ground fault is prevented. For systems up to 4160 V where the resistor let through current is 10 A or less, the arc blast is
