Increase personnel safety with COMBITEST
Inject signals to an isolated protection device to test its performance and operation limits
Helps to ensure that the protection device operates according to your specifications
Before an actual protection operation is
© ABB Group February 3, 2012 | Slide 12
Before an actual protection operation is called for
Perform secondary injection testing of any protection and control IED and protection relay without disconnecting secondary instrument transformers
No external shorting links are needed on the test handle
COMBITEST Safety for both personnel and equipment
© ABB Group February 3, 2012 | Slide 13
When the test-plug handle is inserted into the test switch, the preparations, are automatically carried out in the correct sequence
Blocking of tripping circuits, short-circuiting of CTs, and opening of voltage circuits
Eliminates the risk of accidental opening of the CT secondary, and tripping a circuit breaker
After testing, the protection device automatically returns to its reset position before the connection to trip circuits is restored
COMBITEST
Designed to simplify routine tests and commissioning work
Fail-safe sequence-controlled secondary injection tests
No risk for accidental trip of the circuit breaker
Complete isolation of the secondary circuits of the measuring transformers
Test-plug handles and test switches available in three sizes
RTXH 8, RTXH 18, RTXH 24 test-plug handles

RTXH 8, RTXH 18, RTXH 24 test-plug handles
RTXP 8, RTXP 18, RTXP 24 test switches
Trip-block plug (RTXB) for isolating a trip circuit without interrupting other circuits, monitoring of the trip output and visual indication of an isolated trip circuit
Ammeter test-plug (RTXM) with local automatic shorting device in case of inadvertent opening of a CT circuit, for instance due to opening of leads connected to an ammeter
Block-plug handle (RTXF) for disconnecting all circuits routed through the test switch
