Megger views overhead line profiles
June 2010
Electrical Power & Protection
With virtually unlimited data recording capacity, easy installation and lightweight durable construction, distribution profilers in Megger’s MDP series give power utilities a convenient and accurate way of acquiring the key information needed to monitor power flow on feeders and overhead lines. Three models of MDP distribution profiler are available, ranging from a simple current only version to an advanced unit that offers a number of market requested features such as waveform capture and harmonic analysis.
The economical entry level MDP1 can record RMS current amplitudes up to 1000 A, with an additional 200 A of over range. The mid-range MDP2 adds recording of RMS voltage together with power and power factor, while the advanced MDP3 provides facilities for waveform capture as well as the recording of harmonics and THD. Should user requirements change, the MDP1 and MDP2 versions can easily be upgraded to offer MDP3 features.
All Megger’s MDP distribution profilers have a large non-volatile memory that allows for almost unlimited data recording. In addition, data is safely retained even if the unit’s batteries fail. The RMS response interval of the instruments is user selectable from 10 to 60 cycles and the storage interval may be set from two seconds to six hours. Depending on the response and storage intervals selected, the profilers can record for days, weeks or even months.
To complement its MDP distribution profilers, Megger offers its versatile Metrosoft software package. This is menu driven and includes many powerful features such as: ‘fill in the form’ instrument set up and configuration; data retrieval from up to four profilers at a specific site; specific data file location and voltage/current and demand data chart access.
With this unique combination of instruments and software, system planners, distribution engineers and trouble shooters can easily acquire, access and review data for such purposes as peak load time and growth studies, phase and load imbalance surveys, time and day fluctuation and capacitor bank placement analysis.
