☑ How To Check Rotating Diode

They are covered in the yd gen end manual but a certain amount of disassembly is required. Set the multimeter to measure ac or dc voltage as required.

Keep the digital multimeter dmm in diode checking mode by rotating the central knob to.

How to check rotating diode. Rotating diodes checking if that is the set in your post then im with jim if it is a different one let us know. If so the capacitors need to be discharged. Voltage may be present in the circuit due to charged capacitors.

If the displayed. Connect the red probe to the anode and black probe to the cathode. Rotating diodes are a bit of a pain to check.

Turn the dial rotary switch to diode test mode. Observe the reading on meter display. In this mode multimeter is capable to supply a current of 2ma approximately between the test leads.

Diode mode testing procedure identify the terminals anode and cathode of the diode. The function of the rotating diodes is to rectify the ac output of the excitor into dc which can be used to magnetise the main field windings and poles. Keep the digital multimeter dmm in diode checking mode by rotating the central knob to the place where the diode symbol is indicated.

Identify the diode terminals anode and cathode. Make certain a all power to the circuit is off and b no voltage exists at the diode. Rotating diodes are diodes fitted in the rotor of the synchronous machine between the excitor and the main field winding.
