Questions:
The controller is an SCR with phase angle control. If conducting angle is small only two phases conduct. And voltage decrease with decreasing conducting phase angle.
If the dummy test is with two phases conducting and the real test is with larger phase angle and three phases conducting, what does this mean for the issue discussed here?
The inconel doped resistors are wound in spiral around the alumina. So it's an inductor in addition to resistor. Will the alumina conductivity increase at High temperature and the inductor transfer energy by inductive heating of the alumina in the real test? What would that mean to the issue discussed here?
