GROUND RISE POTENTIAL THE CAUSE OF NUMEROUS FATALITIES
Ground Rise Potential (GRP) occurs in every instance in which an earthed network becomes live.
ADDRESSING ONE HAZARD MAY CREATE ANOTHER
It may not always be possible to protect the pole top worker and the ground worker simultaneously.
Better Protection Less Cost
The inclusion of jointed steelwork in the short circuiting current path will result in slower tripping times and less protection for workers.
“A SAFETY PROCEDURE THAT DOESN’T WORK”
Current flows in all current paths. (Ohms Law)
Induced Voltage and the Transformer effect.
The presence of induced voltage may vary from day to day, hour to hour or minute to minute.
SAFETY PROCEDURES THAT INCREASE DANGER
Numerous tests prove that grounding a machine provides no protection to ground workers or machine operators.
