High voltage test techniques. Measurement of partial discharges by electromagnetic and acoustic methods not-for-sale BS EN 1198 on sodium1 Scope This document is applicable to electromagnetic (HF VHF UHF) and acoustic measurements of PDs which occur in insulation of electrical apparatus. 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.
