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.
