PCA101
CABLE FAULT PRE-LOCATION TDR
The PCA101 is a standalone, handheld cable fault pre-location TDR designed with ease of use and portability in mind. The unit is capable of pre-locating faults using the well-known TDR, Impulse Current and Arc-Echo (Arc Reflection) methods. Impulse Current and Arc-Echo procedures can be performed in conjunction with any of our standalone AE101 or Modarc high voltage coupling units. The unit is powered by built-in lithium batteries yielding a useful battery life of 8 Hours. The interface is simple to use, and two adjustable cursors will enable the user to measure the distance between any two positions on the screen.
The unit is capable of pre-locating distance to fault in three distinct modes.
– TDR
In the TDR (Time domain Reflectometer) mode the instrument transmits a pulse which is reflected off the far end of the cable. Any impedance mismatches (i.e. Joints, open or short circuits) along the cable are also reflected. The waveforms are easy to analyze.
– Impulse Current
In the Impulse Current Mode a high voltage discharge generated by a surge generator is applied to a faulty cable until the fault breaks down. Thus, the surge energy is then reflected back to its source. Upon arriving at the source it is reflected back into the cable. This continues until the
energy is depleted. The PCA101 will capture and store the current waveform flowing in the cable and display it for analysis.
– ARC-Echo
In the ARC-Echo mode the instrument is connected to the faulty cable via the AE101 Coupling unit. This unit provides the suitable isolation and filtering required to superimpose a TDR waveform on top of the high voltage surge generated by the surge generator. When the high voltage energy arrives at the fault it temporarily breaks it down causing a short term short circuit. The waveforms are simple and easy to analyze and look exactly like TDR waveforms.
