Section 6 of NZS 6114 has been amended, providing the New Zealand civilian and military aviation industries with a Standard covering the design and repair of aviation-related electrical systems in the airport environment, including the aircraft, airstairs, GPU, hangar and workbench.
Committee chair, Blue Freeman, says the update “clarifies and gives guidance on a common method for the safe supply of electricity to installations, facilities and equipment operating at non-standard voltages and frequencies in the aviation environment.”
Up to now, engineers and electricians who design or repair electrical systems in the airport environment haven’t had a common standard to follow when electricity is supplied or used at voltages or frequencies other than Standard Low Voltage (SLV).
However, the hard work put in by the committee developing Amendment 2 – which updated and reintroduced section 6 Aviation electrical installations, facilities and equipment – will address this gap and provide a standardised solution that makes aircraft sufficiently safe to be connected to the national grid.
Standard enhanced with additional technical and informative content
Mr Freeman acknowledged the work done by members of the development committee that crafted the original section 6. The committee that developed the latest Standard has added to their contribution. “This has helped us collectively deliver a Standard which will stand the test of time and meet the demands of the aviation industry,” he says.
Section 6 of NZS 6114 has been enhanced specifically with the addition of technical and informative content in Appendices B and C. Appendix B describes typical electricity converter operation when supplying an aircraft and Appendix C covers in-service electrical safety testing for non-standard systems.
This is particularly helpful in providing licensed industrial electricians with guidelines when they operate within an aviation environment.
“Through the new Standard we now have a reference of recommended procedures,” says Mr Freeman. “This gives us commonality, ensuring those in the industry are safe.”
Time frame reflects extensive consultation process
Reflecting on the 15-month commitment made by the Standards New Zealand-convened committee, Mr Freeman says he has been extremely impressed with the well-balanced grouping of talented aviation and broader industry contributors.
“The investment in time was well-spent,” he adds, “as it allowed us to undertake extensive public consultation and go through a thorough independent review of the technical content of the standard.”
Carmen Mak, Manager of Standards New Zealand, says she is extremely pleased with the release of Amendment 2. “I’d like to thank the members of the committee for their hard work completing this important project.”
