IEEE to Develop Switchgear Standard IEEE PC37.20.8
May 28, 2009 // Published as a news service by IHS
The Institute of Electrical and Electronics Engineers (IEEE) is developing IEEE PC37.20.8 - Standard for Metal-Enclosed Low-Voltage (3200 volts and below) Direct Current (DC) Power Circuit Breaker Switchgear for Traction Power Applications.
The goal of the project is to identify specific requirements of metal-enclosed low-voltage DC power circuit breaker switchgear used in traction power applications, according to IEEE.
IEEE will also revise three existing switchgear standards.
The first, IEEE PC37.10 - Guide for Investigation, Analysis and Reporting of Power Circuit Breaker Failures, will combine the existing IEEE C37.10 standard with IEEE 1325 - IEEE Recommended Practice for Reporting Field Failure Data for Power Circuit Breakers, which will then be withdrawn.
IEEE also approved IEEE C37.16 - Standard for Preferred Ratings, Related Requirements and Application Recommendations for Low-Voltage Alternating Current (AC) (635 volts and below) and DC (3200 volts and below) Power Circuit Breakers.
The standard defines the preferred ratings for:
- Low-voltage AC (635 volts and below) power circuit breakers.
- General purpose DC (325 volts and below) power circuit breakers.
- Heavy duty low-voltage DC (3200 volts and below) power circuit breakers
- Fused (integrally or non-integrally) low-voltage AC (600 volts and below) power circuit breakers.
IEEE also reaffirmed two existing standards: IEEE C37.26 - IEEE Guide for Methods of Power Factor Measurement for Low-Voltage Inductive Test Circuits and IEEE C37.40 - IEEE Standard Service Conditions and Definitions for High-Voltage Fuses, Distribution Enclosed Single-Pole Air Switches, Fuse Disconnecting Switches and Accessories.
