Test Setup for Megger – 3 phases

 

FREJA 546 (Low Level Output Hardware option) is interconnected with a Low-level test 
adapter. The test adapter provides the interface between ABB’s Relion

®

 615/620 series fitted 

with combined sensor inputs and the tester. The test adapter is usually connected to the pro-
tection relay through ESSAILEC

®

 test blocks via connecting shielded cables terminated with 

RJ45 connectors. If the ESSAILEC

®

 test blocks are not installed then the test adapter is con-

nected directly to the protection relay via connecting shielded cables terminated with RJ45 
connectors.
