Horn antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in electric assets like GIS and GIL or MV and HV power transformers. It is a broadband antenna with a flat response which makes Horn antenna suitable in a number of different applications. It has been optimized to operate in a frequency range suitable for PD activity monitoring and it was designed to provide maximum sensitivity and high gain.
Its compact and robust design (passive sensor) makes Horn the optimal sensor for direct installation on high and medium voltage GIS/GIL and Transformers. It can be however virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces.
Horn antenna can be used in conjunction with Techimp Frequency Shifters product range, specifically designed and optimized to get the best performance with Techimp PDCheck.
