Component Specifications

Environmental Requirements

Ambient operating temperature rating of --16�C to 70�C

(4�F to 158�F).

Cable Connections

Drilled bus bars and setscrew-type Cu/Al cable lugs are

standard for utility and load connections.

Circuit Breakers

Draw-out electrically operated power circuit breakers are

standard. The circuit breakers are UL listed and equipped with

shunt trip and a microprocessor-based, true RMS sensing trip

unit for overload and short circuit protection. Service

entrance-rated utility circuit breakers include ground fault

protection.

Generator Set Power Controller

A microprocessor-based generator set power controller contains

the system logic, automatic synchronizer, and generator load

control.

Generator Protective Relays

A microprocessor-based, multifunction generator power control

and management module provides all generator relaying and

control functions.

� Over/Undervoltage. Provides voltage protection by opening

the generator set circuit breaker when voltage strays outside

of preset parameters.

� Over/Underfrequency. Provides frequency protection by

opening the generator set circuit breaker when frequency

strays outside of preset parameters.

� Reverse Power. Provides reverse-power protection by

opening the generator circuit breaker when reverse power

exceeds a preset limit for a preset length of time.

� Loss of Excitation. Provides protection for the generator set

upon loss of field.

Intertie Protective Relays

The multifunction intertie protective relay offers the following

protection:

� Phase undervoltage

� Phase overvoltage

� Over/underfrequency

� Negative sequence current

� Dual setpoint negative sequence voltage

� Potential transformer fuse loss detection

� Phase directional overcurrent

� Rate of change frequency

PD-150 Modes of OperationSelect the operating mode locally with the keyswitch on the front

panel. Initiate operation locally with the Local Control Switch or

via remote contact closure.

Prime Power/Remote ATS Start

The system can parallel up to 8 generators in parallel on an

isolated bus.

Emergency

With utility power connected to the PD-150 utility circuit breaker,

the PD-150 operates as a self-contained emergency standby

switchgear system.

Base Load Generator

The generator set remains paralleled to the utility and is loaded

to a user-adjustable kW level. When generator output power

exceeds local load requirements, the surplus power is directed

to the utility grid. When local load requirements exceed the

generator base load level, the utility supplies the remaining load

requirement.

Isolate

Local load transfers from the utility grid to the generator set.

The system operates independently from the utility source until

an operator terminates Isolate operation.

Import/Export

The customer chooses between exporting power to the utility

grid and importing a user-adjustable level of power from the

utility.

When importing power, the system is configured so that a

constant, user-adjustable kW level flows in from the utility.

Generator output power fluctuates to meet differences between

the utility import level and actual system load.

When exporting power, the system is configured so that a

constant, user-adjustable kW level flows to the utility from the

generator set. Generator output power fluctuates to meet

differences between the export level and actual system load.

The system does not allow the generator set to ever exceed its

maximum capacity.
