In many situations, the most economical solution for power supply is through running a number of smaller generating sets in parallel rather than meeting the load demand with a single large unit. This can especially avoid engine damage due to running gensets under too light load conditions.
This panel is very similar in design to the automatic panel except only providing for manual synchronisation through a set of lights or a synchroscope. Start up and shutdown is manually initiated. The closing of the breakers can be manual or as an option through motorised breakers using push buttons.
Simple manual synchronising: In cases where clients wish to synchronise to existing sets or for budgetary constraints, a full panel is not viable, we offer a simple wall hanging enclosure which would allow all standard instrumentation to remain set mounted whilst the synchronising equipment without any busbarring would be mounted in this panel.
AMF/ATS option: The above panels can be supplied complete with changeover system as a seperate section, thus allowing automatic system start and transfer of load between mains and genset.
A multi section freestanding panel with lockable access doors and fascia labels provides automatic synchronising and automatic load sharing with start up/shutdown on demand. The initial start up of the designated lead set is manual, thereafter the system controls take over to monitor the load and start up/shutdown sets according to the load demand and the preset parameters.
Systems involving three or more units are controlled by a PLC (Programmable Logic Controller) which can be reprogrammed if clients load requirements should change. Two set systems utilise a simple form of load sharing module.
Full output rated copper busbars are provided with a single load take off point up to 5000 Amps. Larger systems require multiple take off points.
A comprehensive set of AC instrumentation is provided for each genset and a manual syncronising facility is provided in the unlikely event of the automatic system failing. Each genset in the system is fitted with a DC box as previously described.
