Techimp HQ S.r.L
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.

PDExpert -
Power Monitoring and Diagnostic Technology Ltd.
The PDExpert is PMDT's third level of Partial Discharge (PD) Expert Diagnostic and Location System. It is a powerful, portable, multi-channel system of impeccable design used to analyze and pinpoint PD signals coming from a power asset within centimeters while the power system is energized. The system consists of UHF, AE, HFCT and ultrasonic sensors, one advanced UHF/PD signal processing unit, one oscilloscope, filters and other accessories.The system employs ultra-high speed data acquisition and advanced digital signal processing technologies, compares the UHF, AE and HFCT signals of different frequency ranges to determine if it is PD or noise, and locates the source in power assets accurately by utilizing Acoustic-Electromagnetic Combination Location Technique, time Difference of Signals' Arrivals (TDOA), and 3D Positioning Technology.

Sifos Technologies, Inc.
While most PSE ports are part of multi-port PSE, behaviors of such systems of PSE ports are beyond the scope of IEEE 802.3 specifications. Sifos offers two fully automated analyzer suites that uniquely characterize PSE port administration and power management behaviors including PD admittance policies, PSE capacity management, LLDP policies, and powering stability. Each of these suites are built upon Live PD Emulation, a feature that enables each test port to independently and continuously emulate user-described PD’s.

PD-01LM -
Hachmann Innovative Elektronik
With a PocketDetect LRM you have a highly specialized, miniaturized and easy-going voltage detector at your fingertips. A thorough self-test ensures reliable function. A permanently enabled interface-tester warns against defect interfaces or residual voltages, while the low-power long-term display mode secures live working. The PocketDetect can be carried along due to its diminutive dimensions and lightweight (e.g. in the optional available belt case).

PD-LT -
ndb Technologies Inc.
The PD-LT allows online partial discharge detection on cable accessories such as cable head for safety and maintenance purposes.The PD-LT indicates the intensity of the partial discharges, converting the electrical charge units (pC) into decibels (dB). Thus the reading is kept as a simple intensity level indication, proportional to the probability of a fault's presence in the tested medium voltage accessory.The remote display gives a dB value of the probe's measurement. The dB value will vary along with the discharges indicators on the PD-LT probe. The measurement range is from 0 to 65dB and the display will show ''OL'' if the reading is over 65dB.
