INTRODUCT IO N T HIS MANUAL

1Introduction
1.1 This manual
The engineering guide provides information for the UniGear Digital solution by providing
details about its main components. This guide focuses especially on the IEC 61850 digital
communication and it can be used as a technical reference during the engineering phase.
1.2 Intended users
This manual is intended for to be used by design, protection relay, test and service engineers.
The protection relay engineer needs to have a thorough knowledge of protection systems,
protection equipment, protection functions, configured functional logic in the Protection
relays and their IEC 61850 engineering. The test and service engineers are expected to be
familiar with handling of the electronic equipment.

2 1VLG5 00007 E
2UniGear Digital
UniGear Digital is a new solution implemented to the traditional UniGear switchgear. It is
accomplished by using state-of-the-art, well-proven components: current and voltage
sensors, Relion® protection relays and IEC 61850 digital communication.
The design of the current sensors is very compact and it is optimized for the use in UniGear.
Each panel can accommodate two sets of current sensors. The voltage sensors are very
compact as well. They are integrated as part of support insulators housed in the cable
compartment or directly in the busbar compartment.
The current and voltage sensors are very accurate (accuracy class 0.5), however revenue
metering might require higher accuracy classes or separate instrument current and voltage
transformer. Such transformers can optionally be added to sensor-equipped panels.
Capacitive voltage detection is enabled by capacitive dividers that are either integrated into
the support insulators or into the conventional current transformers, which is used case by
case.
Fasthorizontal GOOSE communication for inter-panel (bay-to-bay) signalsexchangeis
a mandatory part of this solution, whilethe Process bus is optional.

2.1.1 Current sensors
Current measurement in KECA sensors is based on the Rogowski coil principle.
KECA 80 C104 / KECA 80 C165
For dynamic current measurement (protection purposes) the ABB sensors KECA 80 C104, and
KECA 80 C165, fulfil requirements of protection class 5P up to an impressive value reaching
the rated short-time thermal current Ith (31.5 kA or 50 kA). With KECA 80 C104 and KECA 80
C165 sensors, measuring class 0.5 is reached for continuous current measurement in the
extended accuracy ranges from 5 % of the rated primary current Ipr not only up to 120 % of Ipr
(as being common for conventional current transformers), but even up to the rated continu-
ous thermal current Icth (1 250 A or 4 000 A). That provides the possibility to designate the
corresponding accuracy class as 5P400 and 5P630, proving excellent linearity and accuracy
measurements.

Technical parameters
–Continuous thermal current 1 250 / 4 000 A
–Rated primary current 80 A / 150 mV at 50 Hz or 80 A / 180 mV at 60 Hz

KECA 80 C184 / KECA 80 C216
For dynamic current measurement (protection purposes) the ABB sensors KECA 80 C184, and
KECA 80 C216, fulfil requirements of protection class 5P up to an impressive value reaching
the rated short-time thermal current Ith (31.5 kA). With KECA 80 C184 and KECA 80 C216
sensors, measuring class 0.5 is reached for continuous current measurement in the extended
accuracy range from 5 % of the rated primary current Ipr not only up to 120 % of Ipr (as being
common for conventional current transformers), but even up to the rated continuous thermal
current Icth (1 250 A or 3 150 A). That provides the possibility to designate the corresponding
accuracy class as 5P400, proving excellent linearity and accuracy measurements.

KECA 250 B1
For dynamic current measurement (protection purposes) the ABB sensors KECA 250 B1, fulfil
requirements of protection class 5P up to an impressive value reaching the rated short-time
thermal current Ith (31.5 kA). With KECA 250 B1 sensors, measuring class 0.5 is reached for
continuous current measurement in the extended accuracy range from 5 % of the rated
primary current Ipr not only up to 120 % of Ipr (as being common for conventional current
transformers), but even up to the rated continuous thermal current Icth (2 000 A). That
provides the possibility to designate the corresponding accuracy class as 5P125, proving
excellent linearity and accuracy measurements.
