To start with, the Magnelab RCT-3600 is a single-phase flexible Rogowski coil (Rope CT) that measures AC current up to 15,000 amps with an output of 0.333 Vac (with integrator). Incidentally, the coil’s accuracy leads the industry with 0.5% linearity accuracy. The coil provides an output of 0.070 volts AC at 1000 amps through the primary when operating at 60Hz (at 50 Hz the output is 58.33 mV per 1000 A). Furthermore, it has a 36″ length, 12″ diameter and is extremely flexible.
The flexible Rogowski coil opens at the connector junction and may be installed on a bus bar or existing cable in a matter of seconds. The RCT-3600-000 is sold without an optional integrator. See the RCT-3600-250 through RCT-3600-3000 to purchase this Rogowski coil with a single-phase integrator.
For areas with limited space, you may purchase a uniquely shaped version of the RCT-3600 (RCT-600T), also known as a ‘tear drop’ because of its shape. It may also be purchased with or without an integrator. You may buy the coils individually, or as part of the RCS-3600 three-phase flexible AC current sensor system that integrates multiple coils with an output of 0.333 volt AC and includes an integrator and power supply.
