Abstract : An investigation was made to determine safe and efficient electromagnetic interference measurement techniques which will permit detection and measurement of conducted electromagnetic interference emanating from high voltage power lines. It is recommended: That on high voltage circuits and lines the current be measured instead of the voltage. That the current from machinery and substation circuits rated below 15,000 volts line to line be measured with a current transformer or probe designed for 10,000 volts to ground. That the current in distribution lines up to 15,000 volts line to line be measured with a high voltage current proble similar to one described in report or by means of an insulated bucket type lift truck and a low voltage current probe. That the current be measured on lines up to 130,000 volts by means of the insulated bucket type lift truck. (For voltages up to 130,000 volts the shielded cage used for tests made 345,000 volts and described in this report, is not needed.) For all the above measurements the presently available a-c operated FI-RI meters can be used since battery operated inverters can be carried in the lift-truck bucket along with the instruments.
