Description

Synchronoscope ShchS96 is designed for synchronisation of three-phase generators for parallel operation by the method of precise synchronisation in manual and semi-automatic mode.

The device has two measurement channels with display of measurement parameters and generated auxiliary signals on the front panel of the devices, with information transfer via RS485 interface (Modbus RTU protocol) and influence on the external switching device for connection of the synchronised generator to the network when synchronisation conditions are met. ShchS96 is included in the State Register of measuring instruments of the Russian Federation No.

78531-20. Interverification interval is 4 years.
