High Voltage Switches Subcommittee


Scope

Treatment of all matters relating to indoor and outdoor switches and interrupters rated above 1000 V ac and 3200 V dc except for the following devices:

  1. Distribution cutouts.
  2. Switches used in metal-enclosed and pad-mounted switchgear.
  3. Separable insulated connectors.
  4. Circuit-breakers, circuit-switchers, sectionalizers and reclosers.
  5. Gas-insulated switchgear.
  6. Capacitor switches.
  7. Switches rated 38 kV ac and below used on distribution systems except air insulated overhead applications.
  8. Fuses equipped with integral switches.

What's new in C37.30.1TM-2011?


  1. C37.30.1TM-2011 now references C37.100.1TM-2007, IEEE Standard of Common Requirements for High Voltage Power Switchgear Rated Above 1000 V, Annex B, (normative) Altitude correction factors. For users of C37.30.1TM-2011 it is important to recognize that this Common Requirement supersedes all previous altitude corrections and is more stringent than previously utilized information.
  2. A tutorial on C37.30.1TM-2011, Annex C, (informative) Application conditions for continuous load current capability. This tutorial is intended to increase understanding of ACCC designations and applications.
