HV Diagnostics EZ-Cable ID Now Part of Protec’s Rental Inventory

HV Diagnostics EZ-Cable ID Test InstrumentThe HV Diagnostics EZ-Cable ID Test Instrument allows electrical testing personnel to accurately and effectively identify either one or three cables or cores anywhere along the length of the cable in one identification process. This can be done on both single phase and three phase networks. In addition to identifying the correct cable and phase, the resultant current and frequency in a cable can also be measured by the instrument.

The test set consists of 3 main items: A receive (Rx), transmitter (Tx), and inductive clamp/s, all housed in a rugged, injection molded carrying case. The instrument is extremely easy to use and can be powered by either the internal battery, AC mains or from an auxiliary 12V DC supply. The receiver has a backlit LCD display, is battery operated, housed in a rugged, rubber holster and has a flexible pickup coil to easily wrap around cables.

Understanding cable system configurations …

The three cables that make up a 3 phase circuit can be placed in different formations.  Typical configurations include the trefoil or triangular and the flat formation.  The choice will depend on several factors like screen bonding method, conductor area and available space for installation.

Locating Faults on Low Voltage and Pilot Cables

Aquatronics EG 3000 Secondary Cable Fault LocatorIn past blogs we discussed methods for localizing and pinpointing faults on medium and high voltage electric power cables.  These methods focused on the use of high voltage surge generators (thumpers), high voltage radar techniques (arc reflection) plus electromagnetic and acoustic pinpointing.  These techniques work well for medium and high resistance faults on shielded cable structures, but do not lend themselves to low voltage cables or pilot cables (signal and control lines).
