RD Tx-10 Isolation Transformer
The Radiodetection 10/TX121-EN is used with the Tx range of transmitters. Designed to help in locating core-to-core short faults on twisted core-type 3-phase LV mains distribution cables.
Radiodetection’s Tx-121 isolation transformer can be connected
across a pair of shorted faulty cores on a buried, live, or out
of service, LV cable* to couple a locating signal from a Tx-10
transmitter. The location of the fault can then be determined using
a suitable Radiodetection Precision Locator*.
The Tx-121 helps to reduce the need for exploratory digs and
‘cut-to-find’ isolation tasks, reducing the cost of repairs and
minimising disruption to the public.
*Rated for connection to CAT IV mains circuits up to 230V phase-to-neutral.
Maximum phase-to-phase voltage differential: 3V rms at 50/60Hz.
