Secondary test setups
There are different secondary testers with a wide range of additional functionality available
on the market. The testers are primarily operated over a PC with corresponding software
which brings additional functionality to the end user. The secondary tester providing support
to low level outputs (linear, Rogowski) is connected via a testing cable or via adapter to the
sensor input of the protection relay. This section describes how to use testers from Omicron
and Megger. Moreover, it is indicated how these testers can be used for 3 phase testing and 1
phase testing of protection relays.
Test setup for Omicron – 3 phases
Low-level outputs of the CMC tester (for example CMC 850; CMC 356; CMC 256plus; CMC 353
/ CMC 430) are connected to an adapter CMLIB REF6xx / LLX1 used to connect ABB’s Relion
®
615, 620 and 640 series fitted with combined sensor inputs. The testing adapter is usually
connected to the protection relay through ESSAILEC
®
test blocks via connecting shielded ca-
bles terminated with RJ45 connectors. If the ESSAILEC
®
test blocks are not installed then the
testing adapter is connected directly to the protection relay via connecting shielded cables
terminated with RJ45 connectors.
