MDP Series Megger Distribution Profilers - Surgetek

MDP SeriesMegger Distribution ProfilersAPPLICATIONSThe Profilers are quickly installed at any point on thedistribution line. An arrow on the back of the MDP unitshould point towards the load. Since all units aremechanically identical and weigh less than 4.6 lbs (2.1 kg),they are easily mountable to many readily available clampsticks for installation on live lines. Cable diameters from0.2 in. to 1.2 in. (.5 cm to 3.0 cm) can be accommodated.The Profilers are quickly installed at any point on thedistribution line and are mountable to many readilyavailable clamp sticksFEATURES AND BENEFITS■ Virtually unlimited data recording — Depending onthe RMS storage interval selected, the Profiler can recordfor days, weeks, or even months. The unit offersvirtually unlimited data recording/storage capacity withno potential loss, even with battery failure.■ Wide range of data recording options — Recordnecessary data ranging from a simple survey study to acomplete circuit analysis including conductor sizing andcapacitor placement.■ Effective performance and protection — EachProfiler performs effectively when in direct exposureto all weather conditions. The molded unit offersthe greatest protection against water ingress, a majorissue encountered by power utilities using other linerecording devices.■ Easy battery replacement and plug-in access —Lightweight, durable unit with simple plug-in access andtrouble-free battery replacement.■ Easy installation — The light weight of the Profilerallows for quick and easy installation on live lines. It iseasily mountable to many readily available clamp sticks.SPECIFICATIONSAll specifications at 25° C unless otherwise specifiedConductor Size0.2 in. to 1.2 in.
