The Tx-121 isolation transformer is a Tx-10™ transmitter accessory designed to help in locating core to core short faults on a 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 RD7000+™ or RD8000™ 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.

Once the route of the buried cable has been established and marked, the Tx-121 is connected across the faulty cores, with the Tx-10 connected to the Tx-121 input. A low frequency locate signal is generally recommended. By using the locator with the blade inline with the direction of the cable’s route, the operator can follow the regular variations of signal strength as the connected cores twist in the cable – known as the cable lay effect. The position of a fault is identified by a drop in the relative signal strength. Cable joints may also be located using the Tx-121 with the Tx-10 transmitter.
