(Transmission & Distribution World Via Acquire Media NewsEdge) Cable Fault Pinpointer The new MPP2000 pinpointer from Megger incorporates a large backlit color display that not only shows magnetic and acoustic signal levels, but also the relative distance and direction to the fault.

Used in conjunction with a high-voltage surge generator to create a flashover at the point of the fault, the pinpointer detects both the electromagnetic and acoustic signals produced by the flashover. The instrument evaluates the time difference between these signals and uses this to determine the relative distance to the fault, thereby eliminating the misleading results that are often produced by instruments that rely on signal strength alone.

The MPP2000 pinpointer incorporates two electromagnetic signal level indicators, allowing it to provide information not only about the direction to the fault, but also the actual route of the cable. Also provided is a bright LED indicator that gives instant confirmation that an electromagnetic signal has been detected, even if there is no acoustic signal present.

To ensure reliable operation even in the most difficult applications, the MPP2000 uses a lightweight ground microphone with an integral windshield, and it is supplied with headphones. User adjustable bandpass filtering is also provided for enhanced background noise suppression.

The MPP2000 pinpointer has an operating temperature range of -20°C to +50°C (-4°F and 122°F) and is housed in a lightweight ergonomic case with an IP54 protection rating, making it suitable for use outdoors even in demanding weather conditions. The combined electromagnetic probe and ground microphone is lightweight yet robust, and can be disassembled for easy transportation and storage.

Megger | Real-Time Transmission Line Monitoring System Promethean Devices has developed a non-contact, real-time sensor system for the monitoring of high-voltage overhead transmission lines. The system uses calibrated ac magnetic field sensors (located roughly under the phase conductors) to accurately and reliably measure the three-phase ac magnetic fields. System operation and accuracy are not affected by wind, rain, ice, snow, dust or smoke. Once installed in the transmission right-of-way and calibrated, the system reports three-phase currents, conductor clearance and maximum conductor temperature; an IEEE-738-consistent dynamic ampacity/rating is then estimated.

The RT-TLMS is installed just above or just under the right-of-way surface, as determined by ground conditions, terrain or utility/TO/ISO end users. Solar panels and system electronics are above ground; batteries are below ground. Transmission outages are not required for installation, calibration or maintenance. The RT-TLMS employs rugged field-proven equipment, assemblies, components and materials.

Given a static IP address, secure data is transmitted wirelessly to any designated database where it may be accessed only by authorized users. The data is also displayed by a password-protected, real-time, web-based graphical user interface.

Diversified Products | Oil Condition Monitoring Sensor Solution Tan Delta offers a range of highly accurate oil condition monitoring solutions that accurately monitor multiple critical oil parameters and provide instant real-time oil condition status reports.

Research shows that a reduction in oil quality within an electricity transformer has a material and potentially catastrophic effect on its performance and reliability. Therefore, it is essential that suppliers and operators monitor the condition of the oil and take action to ensure optimal performance when necessary.

Tan Delta has developed two solutions that can be implemented by transformer manufacturers and utility operators. Both leverage the proven performance of the OQS Series 2 oil sensor which uses patented technology to simultaneously monitor multiple elements in the oil to provide accurate real-time data on the condition of the oil in the transformer.

The OQS Series 2 sensor itself can be permanently fitted to virtually any tansformer and provide constant real-time data on the oil condition. This data can be integrated with existing monitoring systems or as a stand-alone system.

The Mobile Oil Testing Kit is used by maintenance teams to test oil immediately on site. This negates the normal delay and cost associated with sending oil to distant laboratories for testing. Immediate condition awareness also allows the team to take action while on site, further reducing cost.
