Analyses of these results have shown that a high voltage research laboratory is a source for large electromagnetic fields. The 80 kV pulse generator used resulted in fields of up to 80 V/m and 160 mA/in at a distance of 10 meters from the pulse source.
These values can cause immunity problems to sensitive equipment. Therefore, without further increasing the distance from the pulse source, any PC’s or sensitive equipment will require additional shielding to guard against any high incident fields from causing failures or maloperations.
In addition, these field measurements were extrapolated to allow a direct comparison with similar results from a substation. Therefore, it may be possible to use laboratory simulation to predict the substation environment, as our analysis has shown their results to be equivalent.
