TX-121 Isolation Transformer is used with the Tx range of transmitters to apply a low frequency signal across shorted phases on LV cables to enable location of phase to phase faults. (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).
After you’ve established and marked the route of the buried cable, connect the Tx-121 across the faulty cores, with the Tx-10 connected to the Tx-121 input.
We generally recommend a low-frequency locate signal. With the locator blade in line with the cable’s route, follow the regular variations in signal strength as the connected cores twist in the cable – this is the cable lay effect.
Identify the fault’s position by a drop in the relative signal strength. Additionally, use the Tx-121 with the Tx-10 transmitter to locate cable joints.
