  • Page 16: General Description Of Ovr-15, 27 & 38 Recloser

    RECLOSER IGH VOLTAGE ASSEMBLY The high-voltage assembly of the OVR-15, 27 & 38 consists of three poles mounted onto a common housing. Each of the poles is a separate assembly comprised of a vacuum interrupter assembled in a HCEP molded pole. All the three poles are gang operated by a single coil magnetic actuator through a common operating shaft.

  • Page 17: Recloser Pole And Current & Voltage Sensor

    The current (I) sensing is by current transformer (CT) and voltage (U) sensing is by a voltage divider. The sensor secondary connections are bought out of the pole via shielded cables. In OVR-15 & 27, option is available for single OR dual voltage sensing per pole. Figure-6.1: OVR-15 Pole with single voltage sensor Figure-6.2: OVR-15 Pole with dual voltage sensor...
