Control module for generator sets - CON-5012
This load transfer panel adds to the CON-2012 equipment the possibility of carry out a no break load transfer between generating set and mains power supply. The load is transferred in ramp.a) When the mains supply is restored, the load transfer between the mains and the genset will be carried out with NO BREAK in the utilization power supply.
b) It allows the genset preventive maintenance connecting or disconnecting the real load with NO BREAK. Doing so, there are no interferences for the receptors and the maintenance quality is better.
c) For programmed utilization of the genset in peak hours, all the load transfers will be NO BREAK.
The Low Voltage Electrotechnical Regulations in force in Spain ITC-BT-40 4.2 for no break load transfers, establishes a series of technical requirements. Some requirements affect the control equipment CON-5012. Other requirements concern the installation. Summarising:
No break load transfers may only take place for generating sets of an output of more than 100 kVA.
Only one no break load transfer switch system can be installed between mains and genset.
The earthing of the genset neutral must be disconnected when the set is connected in parallel with mains.
To make easier the load transfer switchboard construction, ELECTRA MOLINS provides the wiring diagram appropriate to each installation.
