Description
The CTRC series flexible Rogowski coil current transformer can measure AC line current in circuits up to 600 Vac and nominal currents up to 6000 Amps
- They open up for easy installation around bus bars and multiple parallel conductors
- CTRC Rogowski coils offer excellent linearity, low phase angle error, with window diameters of 3.1, 4.5, 7.5, or 12 inches, with rated currents from 250 to 6000 amps
- Easier AC Current Measurement
- The CTRC Rogowski coil current transformers are accurate, flexible, rope-like current sensors that can be connected around conductors
- They greatly simplify AC current measurements of conductors where traditional split-core and solid-core CTs are difficult to use
- With its flexible design, the CTRC is perfect for large bus bars and irregular-shaped conductor bundles
- In addition, the coil’s small profile allows it to fit into tight spaces where rigid CTs won’t fit
- Fully Compatible with Wattnode® Meters
- Sold individually, the CTRC coils can be used for single-phase and three-phase services
- The output of the CTRC’s flexible coil is connected to a conditioning circuit, where it is converted to a safe 0.333 Vac low-voltage signal which is compatible with WattNode meters
- Complete Solution
- Four standard models are offered covering various conductor sizes and current ranges from 250 A to 6000 A
- Non-standard currents ranges and window openings are available as custom orders
- CTRC Rogowski coils are supplied with conditioning circuit pre-wire to coil and standard 8 ft. (2.4 m) black and white CT wires for connection to the WattNode meter
- Safe: 0.333 Vac output at rated full scale current—no need for shorting blocks!
- Low phase angle error: essential for accurate power and energy measurements
- Approvals: UL Recognized, CE Mark, RoHS
