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


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


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
