Hi Brian The reference voltages to clearance and creepage are the same as the ones used in the dielectric strenght test of subclause 20 (showed on the second column of table 16, tests A-a1 to B-e). If the sequence of testing in appendix C is used, the dielectric strenght tests are made before subclause 59 on constructional requirements, so you´ll already have the reference voltages (AC or DC depends on the voltage stressing the insulation being tested). Both clearance and creepage use the same reference voltage, which is usually the highst voltage stressing the insulation.
Hope it helps. -- Marcelo de Moraes Antunes - [email protected] Technological Research Institute IPT - Electrical Evaluation Laboratory LAE-ATEE-DME Phone +55 (11) 3767-4948 Fax +55 (11)3767-4007 De: "Brian O'Connell" <[email protected]> Para: "'[email protected]'" <[email protected]> Assunto: IE C60601-1 table 16 Data: 13/08/03 22:56 Good People Would someone please provide relevant clause that explains how to use this table. Are the peak/dc and rms WV used seperately to determine clearance & creepage, as in 60950? or is the greater of the dc or ac WV used to determine both crp & clr ? Is the same measurement technique for determining WV as in 60950, 1010-1, etc ? thanks much Brian ________________________________________________ Message sent using UebiMiau 2.7 -- Marcelo de Moraes Antunes - [email protected] IPT - Instituto de Pesquisas Tecnologicas do Est.de SP Laboratorio de Avaliaçao Eletrica LAE-ATEE-DME Fone +55 (11) 3767-4948 Fax +55 (11)3767-4007 ________________________________________________ Message sent using UebiMiau 2.7.8 ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
