The Rogowski Coil Current Transformers are designed to convert an AC operating current into a low voltage AC millivolt signal for use with microprocessor-based circuits that require the highest accuracy and precision. The Flexible Rogowski Coil is designed to use where regular solid or split core current transformers cannot fit and are ideal for power quality monitoring, such as harmonics. Advantages include high accuracy, wide measurement and frequency range, and no additional integrator or power supply is needed. Rogowski coils come standard unterminated stripped and tinned lead wires for easy connection to any of the Single or 3 Phase ACI power meter.
