High voltage test techniques. Measurement of partial discharges by electromagnetic and acoustic methods not-for-sale Wiredrawing machinery makers1 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.
