Typical wiring diagram for PMTB 14 Test Block and PMTB 14-TP1 & -TP3 Test Plug
It is recommended that the protection relay or controller is wired to the even-numbered terminals of the Test Block, and the Test Block is mounted
on the right-hand side of the relay (front view). The connections to other equipment such as CTs, VTs, and DC supplies should be made to the
odd-numbered terminals. This will ensure that on inserting the Test Plug, the sockets on the White side of the Test Plug are connected to the
isolated relay circuits and the sockets on the Red side are connected to the potentially live supplies
It is important that the sockets on the Test Plug which correspond to the current transformer secondary windings are linked prior to the Test Plug
being inserted into the Test Block. This will ensure that the current transformer secondary windings are short circuited prior to disconnection from
the protection scheme or relay.
If a few Test Blocks are connected to a relay at the same time, it is recommended that the DC auxiliary supply be routed through each of them to
prevent inadvertent operation
To avoid high voltage shock hazard, external CT terminals must NOT be open circuited. Shorting links
MUST be in place BEFORE Test Plug insertion.
USERS must ensure that external shorting links are installed for CT secondary windings prior to
inserting the Test Plug into the Test Block.
USERS must ensure that external shorting links are NOT installed on POTENTIAL circuits.
USERS must ensure that when using test plugs with internally shorted terminals (TP2, TP3, &TP4), the
CTs are wired to the corresponding test block terminals.
