Line Entrance Module
With the Line Entrance Module, several functions
and apparatus previously located in various places
in the switchyard can be integrated on a common
structure.
Introduction
Network operators increasingly require substation
equipment with:
Higher availability
Lower maintenance costs
Smaller space requirement
Enhanced safety
Lower installation cost
To meet the above requirements, ABB Switchgear is
introducing a new concept, Switchgear Modules.
Switchgear Modules available today are:
Switching Module
Line Entrance Module
Energy Metering Module
The Switchgear Module concept is based on three
basic design principles:
Time proven ABB high voltage (HV) equipment with
extensive, and impressive, service records.
Optical transducers for current and voltage metering.
Modern communication technology, including optical
links, used for control and protection.
Standard equipment
A standard Line Entrance Module consists of the
following HV equipment:
CPA/CPB Capacitor Voltage Transformers or
DOVT Digital Optical Voltage Transducers NVA Earthing Switch
Optional equipment
In addition to the standard equipment, the Line Entrance
Module can also be supplied with the following optional
equipment:
PEXLIM Surge Arresters
DOCT Digital Optical Current Transducers
Energy Metering Module (combined DOVT/DOCT)
A complete 3-phase unit Line Entrance Module includ-
ing CVTs, Earthing Switch and Surge Arresters is
tested.
