Insulation for hazarous voltage circuits

1998-11-06 Thread WOODS, RICHARD
IEC 950 and its clones require basic insulation between earthed or unearthed secondary hazardous voltage circuits and earthed conductive parts (Clause 2.2.6 and Table 0.1). Can someone please explain why basic rather than operational insulation is required? Let's take a simple example. Assume a h

RE: EMC Limits

1998-10-27 Thread WOODS, RICHARD
TVs and radios have a specified signal rejection. That is, they must continue to operate with a specified minimum signal to noise ratio and a specified minimum signal. That noise signal may be a spurious emission from another product. That derived noise signal is projected to a certain protection d

RE: EMC limits.

1998-10-27 Thread WOODS, RICHARD
Chris the approach you have mentioned is not too different than the one adopted by ETSI. ETSI has adopted the "shared risk" approach to setting limits. The standards specify the limits and the maximum allowed measurement uncertainty. Any measured value up to and including the limit is acceptable as

RE: Required Margin for EMI?

1998-10-26 Thread WOODS, RICHARD
2 dB was the required margin for initial acceptance to the VDE standard for ITE. Of course, the VDE standards are no longer mandatory since the EMC Directive came into effect. The "new" thinking today is to take measurement uncertainty into consideration when determining a pass/fail criteria. For e

RE: Test procedure for C-Tick

1998-10-15 Thread WOODS, RICHARD
You have to look to the standards for the answer. Since the Australian standards follow CISPR, the standards require that you test at the nominal voltage and frequency of the country. Australia's power system is 240V 50 Hz (some areas in the outback can reach as high as 250V nominal). A retest of t
