Split Core & Rogowski CT's Features
The ND SCT series of retro-fit (split-core) current sensors are designed for fast and easy installation without the need to disconnect any loads. High precision units, they are equally suitable for Current or Power measurement - ideal for Energy Management or any form of automation and control systems. An internal precision resistor across the secondary winding of the CT provides a safe low voltage output - no more worries about open-circuiting CT secondary circuits.
