Woodward’s SYNCONpanel is used to connect a mobile generating set to an MCP (mains coupling point). The mains coupling device in this application is a manual operated breaker, connector, or fuses.
For connecting the mobile generating set, integrated current sensing at the SYNCONpanel transfers the load from the mains to the generating set by soft loading. This enables the user to remove fuses or connectors without load.
For disconnecting the mobile generating set, the SYNCONpanel will phase match the frequency and voltage between the mains and the mobile generating set at the MCP, so a manual operation of the mains breaker or fuses is possible.
A built-in synchronous scope gives the operator clear indication of phase shifts.
