請問 8750中的耐電壓測試 以下這段式什麼意思?2 H+ @! t& Z3 d1 A
8.4.2 The dielectric withstand test equipment shall employ a transformer of 500-VA or larger capacity and' [3 i* J. o+ z1 ]0 Y
have a variable output voltage that is essentially sinusoidal or continuous direct current. The applied# ?. N: }& Y5 _1 e9 H8 C% k
potential is to be increased from zero at a substantially uniform rate until the required test level is reached,/ U2 S' `. E8 ~5 G
and is to be held at that level for 1 minute.
$ V4 o6 F$ d; d* i, O- E$ E% kException: A 500-VA or larger capacity transformer is not required if the transformer is provided with a3 k, ~, c/ r" b& J
voltmeter to measure directly the applied output potential./ j/ W/ ^2 T( m3 I0 e
