The Kehui T-P23 has been designed for locating all types of low voltage cable fault, but especially the difficult and troublesome transient and intermittent fault. It is especially suitable for branched cables. The T-P23 has three modes of operation; Time Domain Reflectometry (TDR) where a single unit is used, Travelling Wave (TRS) using simultaneous testing from two units and Voltage Gradient using records from two or more units. The unit can be connected to a suspect cable and can then be controlled locally from a portable PC through its internal Bluetooth transceiver, or remotely over the Internet using its integral GSM/GPRS modem. The resulting signals can be examined in the T-P2X system software to identify the position of the fault.

Features:

- Remotely controllable TDR and Disturbance Recorder designed specifically for low voltage power cable fault location
- Locates permanent, intermittent and transitory faults
- Safe connection to energised cables via heavy duty fused test leads
- Local interrogation through a Bluetooth connection to a PC or Android device
- Internal GSM/GPRS modem allows control and interrogation from anywhere in the world
- Storage of the last 20 events with 64 TDR traces (30 pre-fault and 34 post-fault) plus 10 cycles of AC voltage waveforms
- Triggered from voltage distortion
- Used in conjunction with additional T-P23 units it can provide a 3-phase voltage gradient fault location system. Two, or more, T-P23 units can be configured to operate as a quasi-synchronous Travelling Wave Fault Location System
