I meant surface temperarure of the reactor 142F or 61C. The internal temperatue is probably higher. I do not think it is over the temperature rating of 115C or 239F.
The reactor is a TCI KDRD24L, 208/240v 15 hp 46.2a with a watt loss of 85. I believe it is 3%, but I do not know the inductance.
Yes, the research I have done suggests 55% THID is very high. The design of the drive cabinet is from a third party. I have forwarded my study results to the design engineers and not heard back from them. (About two months ago). I am the installer. I provided the power for these units.
I am on...
In defining hot, this reactor has a temp. rise of 115 C Surface temp was measured at 142 F. The rated ambient temp is 40 C.Ambient temperature in this panel is close to 40 C due to the heat.
The temperature in this reactor appears to be within limits.
What my concern is, there are similar...
I recently installed four VFD's for four air handlers. These are 208v 3 ph motors from 10-20 hp. Three of four drives are running well. Motor currents and temperatures are good at 60 hz.
A 15 hp drive has a line reactor which is excessively hot at 60 hz. It does vibrate quite a bit as well.
I...
