Some types allow direct contact to the windings and thermal device through taps on the transformer, this allows the test current to pass through both the thermal device and winding but allows for the resistance measurement of the winding only). Wiring. The Temperature Classification of internal wiring shall be determined from IEC 60079-11.

Now, the other diode and the other half of the transformer's secondary winding carry current while the portions of the circuit formerly carrying current during the last half-cycle sit idle. The load still “sees” half of a sine wave, of the same polarity as before: positive on top and negative on bottom.
