PowerLogic ADVC Controller CAPE
Figure 5 shows an PowerLogic ADVC Controller CAPE with a flexVUE O.I.
The CAPE for an PowerLogic ADVC Controller has communications ports as described in PowerLogic ADVC Controller.
The CAPEs for PowerLogic ADVC Controller have the same configuration below the O.I., for the switchgear control cable connection and main loom cable connection, as shown in Figure 6.

CAPE connection and isolation
Shown in Figure 6 from left to right are the following:
-
Main loom connector – A 36 - way loom connector used to connect the CAPE to the auxiliary supply, batteries, temperature sensor, battery heater, and equipment tray.
-
CIP - Current injection port for secondary current injection.
-
Trip and close circuit isolation switches.
-
Switchgear connector for the control cable connection.
The CAPE incorporates all the electronics modules and performs the following functions:
-
Protection Relay
-
Network Management
-
Communications
-
Switchgear Control
-
Uninterruptible Power Supply
-
O.I.
The components are assembled in a diecast aluminum enclosure to help protect the electronics against electromagnetic, electrostatic, and environmental influences. Assembly is performed in a controlled environment and the enclosure is sealed to IP65 which helps to ensure maximum reliability throughout the service life of the product.
The CAPE digitizes the Current Transformer (CT) signals and Capacitive Voltage Transformer (CVT) signals from the switchgear. These are used to perform the controller’s protection, metering, and control functions.
