High specification line of flexible current transformers that measures AC current for power metering, power quality analysis and general use. The Rogowski coil provides a versatile solution when space is limited and requires a rope-style CT to physically wrap around a irregular shaped conductor or wire.
All measurements at 25° C and 60 Hz unless otherwise noted
