This document is applicable to electromagnetic (HF\/VHF\/UHF) and acoustic measurements of PDs which occur in insulation of electrical apparatus.<\/p>\n

This specification deals with a large variety of applications, sensors of different frequency ranges and differing sensitivities. The tasks of PD location and measuring system calibration or sensitivity check are also taken into account.<\/p>\n
