TX-121 Isolation Transformer


Your details are sent to our sales team. We will contact you within 24 hours.

TX-121 Isolation Transformer – This 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).

Part No: 10/TX121-XX (XX = DE, EN, FR, NL)

LOCATING A CORE-TO-CORE FAULT – 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.
