ITSM Synchro
The Impulsive Test Synchronization Module (ITSM) is a device aimed at generating a digital synchronization signal, to use the PDBaseII system for impulsive voltage PD test. The digital synchronization signal generated by the ITSM, is synchronized with the voltage impulse of the impulsive source (voltage generator). The ITSM must be connected between the DIN channel of PDBaseII and the output of the synchronization sensor (e.g. capacitive coupler). The ITSM provides also a low voltage signal reproducing the impulsive voltage source.

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
Partial discharge (PD) is a local electrical discharge that occurs in imperfections or inhomogeneities. The partial discharge measurement is a so-called “non destructive test” to determine the quality of insulating materials. On the contrary of pure high-voltage test, th test item is not pre-damaged at low PD levels.
