PER672N Load Share Model

Load Share Model (PER672N)

1)Description----The function of the Load Sharing Module is to proportionally share load between two or more generator sets while the system frequency is held constant.As an accessory to the electronic Governing System,the PER 672 measures the true power current ,and throught a parallel cable interconnection,continuously controls the governor system.

2)Performance
 Load SharingAdjustable to within +/-2% between sets
Performance.Isochronous and droop paralleling and power control
Reverse Power Monitor.Adjustable from 0.5-20% with a 2 second inverse time constant
Forward Power MonitorONtrip point adjustable from 20-100%                       
                                            OFFtrip point adjustable from 0-80%                   
                                               Normally open contacts with a 2 second inverse time constant

3)Power Output

Signal.0 to 7.5 Volts DC representing 0-100% load
All performance specifications are based on 5 amps from the current transformer(CT) Secondaries at full load unity P.F.

4)Power input
AC input signals.. 208 or 416 volt nominal line to line and 5 amp CTs with a minimum 6.25 VA rating.                    Internal 0.25 ohm burden resistors
