1.1 0 - 60 seconds During this load segment the following equipment cannot be operated simultaneously with the others loads.

1.11 HV-E51-1F045 inrush amperes are not use since HV-E51-1F045 MUST BE out of Locked Rotor before HV-E51-1F013 can be started.

1.12 1P155A inrush amperes are not used since this motor has a 6 second definite time timer which prevents simultaneous starting with the other equipment.

1.13 HV-E51-1F010 inrush amperes are not used since HV-E51-1F031 MUST BE closed before HV-E51-1F010 can operate. This prevents simultaneous starting with the other equipment.

1.14 HV-E41-1F079 inrush amperes are not used since Reactor j Pressure MUST drop to 105.5 psi before HV-E41-1F079 can operate. This occurs after all the equipment in this load segment has started. g

l The purpose of this calculation is to calculate the inrush current for 1P125B,

< 1P125C and 1P110 based upon speed when the starting resistors are shorted.

l The equations on the following pages were programmed into MicroSoft Excel PC based program.

The only assumption used in this calculation is that the motor Horsepower (HP) is proportional to the square of the speed. This is based upon:

Head is proportional to speed -

Flow is proportional to speed :-

HP = (Head) (Flow) = K(Speed) 2 .
