TEV Antenna
-
TEV sensor is a partial discharge sensor whose working principle is based on a direct Capacitive coupling with a Switchgears earthed metal case. The two ends of TEV sensor can be coupled magnetically to virtually any opening on a metal Surface. It picks up the electric signal given by PD activity onto the two metallic surfaces. Thanks to its special design has high sensitivity, larger than other single ended TEV sensors. His compact and robust design (passive sensor) makes the TEV the optimal sensor for direct installation on medium voltage Switchgears.

Partial Discharge Testing Equipment
3i
-
The portable multipurpose 3i device (Intellectual Insulation Indicator) is for eff ective high-voltage equipment insulation monitoring on-line. The 3i device measures and analyses partial discharges (PD). For eff ective PD measurement and noise rejection, there are two types of sensors used in the device: the acoustic sensor and the TEV sensor. Both the sensors are built into the device case, and so do not need any connection cables. The device is supplied in a strong metal case; at the faceplate there are the colored screen and two buttons: power button and function button.

Cable Diagnostic Tools
-
For non-destructive diagnostic testing to determine the quality of a cable’s insulation with minimal risk of failure, HVI recommends tan delta and partial discharge testing for valuable diagnostic data about cable insulation integrity. Both use a VLF source to perform elevated voltage, off-line testing. Tan delta testing measures insulation health, while PD identifies specific problem areas and assesses their severity.

Cable Discharge Solutions
-
Cable Discharge Event, or CDE, is an electrostatic discharge event that occurs when a cable is connecting to a piece of equipment with different potential. It occurs because there is a potential differential between the charge on a cable to be connected and the equipment. It doesn't matter if the cable is charged or if the equipment is charged. It's the potential differential that causes the discharge. ESDEMC develops commercial system for CDE reliability test and evaluation.
