Performance Criteria Guideline for Three Explosion Protection Methods of Electrical Equipment Rated Up to 15,000 Volts Ac.

NTIS: PB/84-172303 :63 pages
This performance criteria guideline is an evaluation of three explosion protection methods of machines electrically powered with voltages up to 15,000 V ac. A sufficient amount of basic research has been accomplished to verify that the explosion-proof and pressurized enclosure methods can provide adequate explosion protection with the present state of the art up to 15,000 V ac. The routine application of the potted enclosure as a stand-alone protection method requires further investigation or development in order to clarify performance criteria and verification-certification requirements. A literature search, a series of high-voltage tests, and a design evaluation of the three methods performed at the white sands test facility indicate that the explosion-proof, pressurized, and potted enclosures can all be used to enclose up to 15,000 V ac, if the performance criteria and verification-certification requirements recommended in this guideline are implemented.
