Utility Locating and DetectionRadiodetection Tx-121 Isolation Transformer (English labels)
Part number
10/TX121-EN
An isolation transformer that couples a Tx-10 transmitter signal across a pair of shorted cores on a 3-phase LV cable. It helps find core-to-core faults and cable joints with a precision locator, reducing exploratory digs.
