What Can a
GDP/CGDP be
Used For?
The GDP/CGDP can eliminate the need for discrete substation devices.
For example, the GDP/CGDP can be used in place of the following devices:
• circuit breaker control switch and semaphore
• disconnector / earth switch and semaphore
• ammeter, and ammeter selector switch
• voltmeter, and voltmeter selector switch
• MW meter
• power factor meter
• alarm annunciator panel
• mimic diagram.
!
IMPORTANT
There are jumper settings at the back of the GDP/CGDP unit that are set at
the factory. These settings shall not be changed and any modification to them
may cause damage to the GDP/CGDP or other modules of the D25.
A D25 equipped with a GDP/CGDP has these limitations:
• Only external status wetting can be used when the GDP/CGDP is installed.
− the D25’s power supply field O/P is used exclusively to power the
GDP/CGDP.
− connecting another external load to the field O/P will affect isolation, and
possibly overload the power supply.
• The GDP/CGDP reduces the normal -20° to +70°C operational temperature
rating of the D25 to 0° to +50°C.
• The 20-60 V
DC
D25 power supply is not available with the GDP/CGDP.
