Low Voltage Surge Protective Device Working Groups

Power System Surge Protective Devices (SPDs)

3.6.4 — Surge Characterization on Low Voltage Circuits Working Group
Chair: Doug Dorr
E-mail: d.dorr@ieee.org

  • Define the exposure of low voltage circuits to overvoltages and over-current surges.
  • Organize existing data on the subject and characterize the surge environment
  • Identify areas for further study and refer them to 3.6.
  • Prepare a section on the exposure of low voltage circuits to surges for incorporation into the Low Voltage Surge Protective Devices Application Guide.
  • Prepare a test procedure specification for evaluating surge withstand capability of equipment's connected to the environment developed above.

3.6.6 Low Voltage AC Power System SPDs — Load Side of the Service Equipment
Chair: Ron Hotchkiss
E-mail: ronhotchkiss@ieee.org

  • Establish performance characteristics for surge protective devices packaged to be connected to low voltage AC power circuits for any combination of linear or nonlinear elements.
  • Develop and recommend standard methods for testing and rating these devices.
  • Coordinate and incorporate sections prepared by other groups for single element devices.

3.6.9 — Low Voltage AC Power System SPDs — Line Side of the Service Equipment
Chair: Ray Hill
E-mail: ray.hill@neetrac.gatech.edu

  • Maintain the performance standard and application guide for surge protective devices designed for application on the low voltage ac supply mains (less than 1000 V rms, frequency between 48 Hz and 62 Hz).
  • These documents apply to surge protective devices intended for connection at locations between and including the secondary terminals of the service transformer and the main service entrance panel on the line side of the main overcurrent protective device.

3.6.10 — Surge Protection of Equipment Connected to Both Low Voltage AC Power and Communication Circuits Working Group
Chair: Mick Maytum
E-mail: mjmaytum@gmail.com

  • Develop a guide for the application of multi-service (multi-port) surge protectors to protect equipment connected to ac power and communication circuits.
  • The guide will consider and discuss coordination of the multi-service (multi-port) surge protective devices with other AC and communication circuit protection.
  • The guide will be limited to premises served by 120/240 V ac power, with the neutral bonded to ground at the service entrance.
  • The guide limits its scope to only addressing metallic communications conductors.

Communications System Surge Protective Devices (SPDs)

3.6.7 — Surge Protection for Information and Communications Technology (ICT) circuits including Smart Grid Working Group
Chair: Al Martin
E-mail: amartin_36@yahoo.com

  • Establish performance characteristics for surge protective devices packaged to be connected to low voltage communications and signalling circuits.  These packaged devices may contain a single non-linear component or multiple component combinations of non-linear or non-linear plus linear elements.
  • Develop and recommend standard methods for testing and rating these devices.
  • Prepare sections defining the characteristics and recommended application criteria for these devices for incorporation into the Low Voltage Surge Protective Devices Application Guide.
  • Coordinate and incorporate sections prepared by other groups for single devices.
