BS 3G 100-4.1.1 is an international standard that covers electrical insulation tests for equipment in aircraft, enabling the determination of insulation resistance to ensure the safety and protection of electrical systems and devices.
BS 3G 100-4.1.1 specifies requirements for tests to determine the electrical insulation resistance of equipment intended for use in aircraft, together with a high voltage test.
BS 3G 100-4.1.1 relates the insulation requirements to four categories of equipment.
Note: BS 3G 100-4.1.1 does not relate to the insulation testing of equipment installed in aircraft.
BS 3G 100-4.1.1 on electrical insulation tests for equipment in aircraft applies to:
The operational safety of electrical equipment for aircraft requires a good quality of insulation and the avoidance of excess voltages. Dimensions and quality of the insulation must be suitable for the operating voltages and the effects of climatic conditions encountered, such as temperature, humidity, atmospheric pressure and surface contamination.
BS 3G 100-4.1.1 provides users guidance on high voltage test to determine the capability of insulation to bear the effects induced by the electrical field. BS 3G 100-4.1.1 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly to ensure insulation resistance for electrical equipment.
With obedience and compliance to BS 3G 100-4.1.1, users can assess and implement high voltage test on electrical equipment to ensure safety, resilience and durability in aircraft systems.
