Calibration of UHF Partial Discharge Measurement for Power Transformers And a Comparison to the Calibration of Electrical PD Measurement
The reliability of electrical energy networks depends on the quality and reliability of its electrical equipment, e.g. power transformers. Local failures inside their insulation may lead to catastrophic breakdowns and may cause high outage and penalty costs. To prevent these destroying events, power transformers can be tested on partial discharge (PD) activity before commissioning and monitored...
متن کاملUhf Monitoring of Partial Discharge in Substation Equipment Using a Novel Multi-sensor Cable Loop
This paper describes the development of a partial discharge measurement system that utilises a multiplexed approach to ultra-high-frequency monitoring on many pieces of equipment using a single cable loop connected to only two sampling channels. It is envisioned that the system could be used in partial discharge monitoring of medium voltage metal-enclosed switchgear, or several power transforme...
متن کاملA Novel Partial Discharge Localization Method in Substation Based on a Wireless UHF Sensor Array
Effective Partial Discharge (PD) localization can detect the insulation problems of the power equipment in a substation and improve the reliability of power systems. Typical Ultra-High Frequency (UHF) PD localization methods are mainly based on time difference information, which need a high sampling rate system. This paper proposes a novel PD localization method based on a received signal stren...
متن کاملDesign of a New Built-in UHF Multi-Frequency Antenna Sensor for Partial Discharge Detection in High-Voltage Switchgears
In this study a new built-in ultrahigh frequency (UHF) antenna sensor was designed and applied in a high-voltage switchgear for partial discharge (PD) detection. The casing of the switchgear was initially used as the ground plane of the antenna sensor, which integrated the sensor into the high-voltage switchgear. The Koch snowflake patch was adopted as the radiation patch of the antenna to over...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
