This work presents a new PD (partial discharge) measuring system for inverter-fed motors based on a bridge circuit topology. The bridge circuit was adopted in the measuring system for picking up PD signal and suppressing interference. The experimental results show that it is possible to detect and record PD notwithstanding the large interference due to inverter commutations if measuring frequencies are selected adequately

Abstract
This work presents a new PD (partial discharge) measuring system for inverter-fed motors based on a bridge circuit topology. The bridge circuit was adopted in the measuring system for picking up PD signal and suppressing interference. The experimental results show that it is possible to detect and record PD notwithstanding the large interference due to inverter commutations if measuring frequencies are selected adequatelyFile in questo prodotto:
