gis substation tester for middle voltages

Tagg Slope Test revealed that the grid resistance of 220/110/33 kV substation was islanded. The lower upper yard was islanded while middle yard was in critical state. The earth grid resistance was very high and required a new peripheral earth ring around the grid (1m away) and connect it to the existing grid at every 30 m interval.
