Hi Kamran, I use both change of resistance and a thermocouple as a check. I would expect the thermocouple to read a little below the resistance method. Some standards require the change of resistance method (not the thermocouple method) to be used for compliance assessment of winding temps.

I happen to get involved in this and found that my results are different than the vendors result by as much as 10-15 degrees on measuring on a same magnetic component. Even applying the thermocouple to different location on a coil seems to give you different results. Is there a method that I should be following to measure temperature with thermocouples methods, not change of resistance, on magnetic parts such as transformers, coils, etc.? > > Thanks, > > > **************************************************************************** ******* > Kamran Mohajer > DSL Compliance Lead > Cisco Systems, Inc. > Phone(408)-525-6121 > Fax(408)527-0495 > kmoha...@cisco.com > **************************************************************************** ******* > > --------- > This message is coming from the emc-pstc discussion list. > To cancel your subscription, send mail to majord...@ieee.org > with the single line: "unsubscribe emc-pstc" (without the > quotes).
