SPDC LV Power SPD Working Group Scopes

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: Dr. A. J. (Tony) Surtees
E-mail:
surtees@ieee.org

  • 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.

3.6.11 – Wind Power Facilities Electrical Protection Guide
Chair: Kenneth Brown
E-mail:
kbrown@leviton.com

Surge protection guidance for electrical equipment and systems with voltages of 1000 V(ac) and 1200 V(dc) or less within a wind power facility or wind generation structure. Included within this scope are communications and data acquisition equipment and associated circuitry and interfaces.

3.6.12 – Photovoltaic Facilities Electrical Protection Guide
Chair: Dr. A. J. (Tony) Surtees
E-mail:
surtees@ieee.org

Surge protection guidance for electrical equipment and systems with voltages of 1000 V(ac) and 1200 V(dc) or less within a photovoltaic facility or installation. Included within this scope are communications and data acquisition equipment and associated circuitry and interfaces.

3.6.13 – Smart Grid Electrical Protection Guide
Chair: Matt Wakeham
E-mail:
matt.wakeham@protectiongroup.com

Surge protection guidance for electrical equipment and systems with voltages of 1000 V(ac) and 1200 V(dc) or less for components of the Smart Grid. Included within this scope are communications and data acquisition equipment and associated circuitry and interfaces. Additionally, there are cases, which involve smart grid equipment attaching or coupling to higher voltage circuits such as electric utility medium voltage distribution. This scope is not limited to providing guidance for such matters.
