Hi,

Attached is the measurement that Sonny/Piyush have done this afternoon. The total coil resistance seem to be ~2.4308 Ohm compared to what Sonny measured ~2.53 Ohm last April ( I remembered 2.35 but I’ve just checked, it was 2.53 :-). The temperature in the coils was like ~291 K (+/- ?) now compared to 22 deg. C (~295 K) last Apr. And this time, Piyush said his meter was very accurate (not those Fluke meters that Sonny probably used).

In any case, RRR ~ 2.43Ohm /1.5 mOhm ~ 1620 .

Kin,

Attached is the copy of voltage tap readings at 1A. at the bottom you will find total coil, outer coil and inner coil resistances.

Total : 2.4308 ohms

Outer : 1.2367 ohms

Inner : 1.19331 ohms

Regards

Piyush
