Voltage Sensor

Type: VS (voltage only)
Mounting Orientation: Any Direction
Voltage: 7.5 – 500 kV (line to line)

BIL: 95 – 1470 kV

Accuracy: +/- 5%

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

Application
Replaces conventional oil-filled PT’s, VT’s, CCVT’s and optical sensors in many applications such as voltage monitoring, hot line indication, synchronization checks, and auto-sectionalizing or SCADA operation of switches.

Features & Benefits

  • Small footprint, compact size
  • Less than 10% of the weight of oil-filled PT’s; minimizes supporting structure size and cost
  • Can be mounted in any orientation, including vertical and under-hung; provides flexibility in areas with limited clearances
  • No PT Ferro resonance
  • No catastrophic failure if voltage outputs are shorted
  • Environmentally friendly; no oil or SF6 used as a dielectric; no special material handling or disposal procedures
  • No galvanic connection between potential and ground; electrical isolation is provided through the use of an isolated high potential
  • Generates safe, low voltage outputs
