Rogo Coils for Power Meters

  • Best In Class Linearity - Conventional CTs are wound over a magnetic iron core, which makes them more susceptible to saturation leading to linearity error. Engineers and contractors must adjust the phase shift of the meter to compensate in order to achieve an accurate reading. Rogowski Coils are wound over a non-magnetic core, giving them perfect linearity and improved accuracy over wide current ranges.

  • Installation Savings - Installers can save significant time and labour using the Patrol Flex due to its flexibility and ease of surrounding conductors of all sizes. Selecting a Rogowski Coil instead of a conventional split-core CT can save the installer over two hours per metering point in a challenging installation, which could be the difference between making and losing money on a job.

  • Wide Current Range - The Patrol Flex has a current range of 5 – 5,000A yet weights less than 0.5Lbs, drastically reducing shipping costs. A typical 100A CT weights 2Lbs, however as the current range expands to 3000A, the average weight can increase from 2Lbs to 20Lbs. Considering three CTs are required to a monitor a 3-Phase motor, certain applications could require up to 65Lbs of shipping weight per metering point.
