Techimp TEM Antenna Single phase Kit.

TEM antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset (like MV switchgears or LV and MV induction motors fed by power electronic impulses).
It is a broadband antenna with a flat response which makes TEM suitable in a number of different applications.

It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain.

Its compact and robust design (passive sensor) makes TEM the optimal sensor for direct installation on medium voltage Switchgears and motors.
It can be virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces.
