PTD-2G is a portable power analyzer for measurement and registration of alternating low voltage electricity energy network parameters. The device could be connected directly to voltage lines and to current lines through current clamps or directly. The device could be used in assistance to electricity thief detection. PTD-2G has communication interface for remote data transmission.
