Techimp HQ S.r.L
PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

BAUR Prüf- und Messtechnik GmbH
Cable testing and diagnostics with the BAUR tracy. The BAUR tracy partial discharge inductor induces a signal at the apparent fault location in the cable from outside. In combination with any PD measurement system, e.g., PHG TD/PD, the induced signal can be located and compared with the result of the partial discharge pre-location. The partial discharge location can thus be determined precisely.* Portable, battery-operated signal coupling device* Suitable for cables and cable accessories* Inductive signal coupling* Aviods costly, unnecessary replacements of PD-free cable accessories

Techimp HQ S.r.L
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.

Optoplex Corporation
The integrated 40-Gb/s DP-QPSK receiver incorporates two 90° optical hybrids with four pairs of balanced photodetector (PD) and four linear TIAs into a single butterfly package. Unlike other technologies in which the polarization beam splitter (PBS) and/or the power splitter (BS) are not included, Optoplex’s receiver includes both of them with the optical hybrids, PDs and the TIAs to offer a fully integrated solution which will benefit users in terms of completely removing fiber routing and the skew management. The integrated receivers work at the symbol rate up to 12.8GBaud/s.

High Voltage Inc.
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.
