DENT's RoCoil line of Rogowski Coil CTs offer significant advantages over conventional Split Core or Clamp-On CTs in certain installations. These "rope-style" Current Transformers deliver "installer-friendly" features such as large window size, light weight, wide current range, and mechanical flexibility for mounting in tight quarters. RoCoils provide accurate, non-intrusive measurement of AC current combined with easy placement around cable bundles, large bus bars and irregular shaped conductors. They are available in three models: RoCoil, RoCoil mV and the FLN 3000A Series. See the details of each below.
RoCoil™
Lengths: 16", 24", 36", and 72"
RoCoil mV™
Lengths: 16", 24", 36" and 72"
3000A Flex CTs
Length: 36"
RoCoil CTs are designed for use with DENT's PowerScout™ networked power meters and ELITEpro SP™ instruments. This Rogowski-type sensor produces an output signal (di/dt) of 131mVAC per 1000A at 60Hz (110mVAC/1000A @ 50Hz). These CTs require a customer-supplied integrator/amplifier (such as the one built in to DENT's ELITEpro SP and PowerScout instruments).
Standard Features:
Available in 16", 24", and 36" lengths
Lightweight, flexible alternative to conventional CTs
Like its name implies, the RoCoil mV produces a millivolt output for use with DENT's ELITEpro power meters. These CTs are available in standard lengths up to 72" and current ranges up to 6000A AC. The RoCoil mV requires 5-24V DC for operation, which can be supplied from a Line-Powered ELITEpro or optional external power supply.
Standard Features:
Available in 16", 24", 36", and 72" lengths
1000A, 2000A, 3000A, and 6000A ranges
Max output of 1.66VAC for use with other manufacturer's meters
The DENT 3000A Flexible Current Transformer is composed of a battery-powered flexible sensor and integral battery-powered amplifier/integrator electronics module. It offers a unique, switch-selectable 300/3000A dual measurement range.
Standard Features:
Measure from 20A to 4000A
Dual range: Easily switch between 300A and 3000A
36" length
Battery life is ~4,000 hours (8,000 hours maximum)
Rogowski coils by DENT. These “rope-style” flexible current transformers offer advantages over conventional split core or clamp-on CT's in certain installations. Also available as bare Rogowski-type sensors. Oure RoCoil™ Rogowski Flex Coil CT's can be used with DENT’s ELITEpro and DATApro Series dataloggers.
