When the brushless generator does not generate electricity, unable to determine whether caused by the AVR fault. Do not know where to start checking, China Everlasting Parts Co., Limited as a professional AVR manufacturer, introduce to everyone the brushless generator AVR fault judgment skills.
1:Open the brushless generator AVR shield, unplug the F1 F2 and AVR plug-ins.
2：With 2pcs 1 square meters of power lines, one end with the 12V battery positive and negative poles, and the other end connected with the excitation Coil F2 and F1 respectively. Note that the positive electrode of the battery is connected to the F1, and the negative electrode is connected.
3:Turn on the start power switch, start the diesel generator to 1500 turn to observe the generator voltage and frequency change.
4:Pay attention to the use of electrical safety,When using this method,please do not mistake the line meet the short circuit accident.
5：If the speed of the diesel generator is increased, the voltage is increased, and the voltage is 400V. when the generator speed is up to 50HZ.So to judge the brushless generator AVR damage caused by non power generation, for the generator AVR. On the contrary, when the speed of the diesel generator is changed and the voltage and frequency are not changed, it is not the AVR damager cause Generator does not generate electricity. Check maintenance from other paths.
