Current Sensor

Type: CS (current only)
Mounting Orientation: Any Direction
Continuous Current: 600, 1200, 2000 Amp

BIL: 95 – 1470 kV

Accuracy: +/- .15%

Description
A lightweight monitoring insulator (data collection device) capable of reproducing in phase proportional sinusoidal current wave for communication to customer devices (meters, relays, rtu’s, etc.)

Application
Replaces conventional oil-filled CT’s and optical sensors in applications such as monitoring, metering, and relaying. Accuracy is perfectly linear down to 1% of rated current (burden resistance range 0-2 ohms) enabling highly accurate metering in low current applications.

Features & Benefits

  • Small footprint, compact size
  • Less than 10% of the weight of oil-filled CT’s; minimizes supporting structure size and cost
  • Can be mounted in any orientation, including horizontal (cantilever) and under-hung
  • Hyper accurate; exceeds IEEE class 0.3 accuracy standard for revenue metering
  • Extended metering range over wide currents; accuracy is perfectly linear down to 1% of rated current
  • No CT saturation
  • No catastrophic failure if current output loop opens like conventional CT’s; no need to short the current output
  • Environmentally friendly; no oil or SF6 used as a dielectric; no special material handling or disposal procedures
  • No galvanic connection between high potential and ground. Electrical isolation is provided through the use of an isolated high potential.
  • Generates safe, low current outputs
