Megger finds cable faults fast!
The new PFL22M1500 cable fault location system from Megger provides, in a single rugged and compact portable system, all of the facilities needed for fast, accurate and safe location of faults on underground cables.
• Portable, rugged field-proven CFL and HV test module
|Essential for the pre-location of faults|
|An essential resource for utilities and others concerned with maintaining continuity of supply and minimising customer minutes lost, this new test set incorporates a high-voltage generator with surge generation capabilities and a high performance time domain reflectometer, enabling a wide range of fault pre-location and location techniques to be deployed without the need for additional equipment.|
|A large range of fault location techniques in a small unit|
|Designed for reliability and ease of use, the high-voltage generator incorporated in the new PFL22M1500 provides user-selectable surge output ranges of 0 to 8 kV and 0 to 16 kV, with constant surge energy of 1,500 Joules. It also offers a steady dc output of 0 to 10 kV at up to 115 mA, and 0 to 20 kV at 55 mA. |
These facilities, in conjunction with the integrated time domain reflectometer, support the use of the arc reflection, arc reflection plus, differential arc reflection and current impulse techniques for fault pre-location.
The high voltage generator also allows users to perform conditioning to stabilise faults, and to carry out high-voltage insulation tests. In addition, the surge generator function is an ideal complement for the Megger MPP2000 acoustic and electromagnetic pinpointer for the accurate final determination of fault locations.
|Multipurpose TDR incorporated|
|The MTDR100 time domain reflectometer incorporated in the PFL22M1500 CFL system, has a large 10.4-inch XGA colour display and offers intuitive and convenient single jog-dial operation. It covers distances from 100 m to 55 km in ten ranges, and offers pulse widths from 50 nS to 10 µS. |
When used with the arc reflection plus fault pre-location technique, which is unique to Megger equipment, the MTDR100 can capture up to 1,024 traces during the period of the arc, and subsequently analyse these to provide the best possible fault location information in even the most difficult of cases.
|Can be powered by battery|
|As standard, the PFL22M1500 cable fault location system operates from nominal 110 V or 220 V single-phase supplies, but an inverter module is optionally available to allow power to be derived from a battery source to facilitate use in locations where no convenient mains supply is available.|
