Inter-turn short circuit cannot be measured no matter how you measure the insulation resistance to ground, because the insulation cannot be damaged due to a short -circuit between turns. It is very simple to judge the failure of the stator and rotor. As long as the excitation part and the transmission are good, there is no-load voltage, but not high, and the power smokes, it is a stator failure. easy and there is tension, it is a rotor failure.
Generators are widely used in industrial and agricultural production, national defense, science and technology as well as daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic induction. law of electromagnetic force. The general principle of its construction is to use magnetic materialss and electrically conductive suitable for forming magnetic circuits and circuits that conduct electromagnetic induction between them to generate electromagnetic energy and achieve the purpose of energy conversion.
Detailed informationInstallation procedures for generators:
1. Check the lubricating oil level, coolant level and fuel quantity.
2. Check the lines and joints of the diesel engine's oil supply, lubrication, cooling and other systems for oil and water leaks.
3. Check for leakage hazards such as broken skin on electrical circuits, loose ground wire electrical circuits, and firm connection between the unit and the foundation.
4. When starting the diesel generator for the first time or restarting it after a prolonged shutdown, you mustord use a hand pump to drain the air in the fuel system.

What is the impact of ambient temperature on diesel generator sets
It may be due to the five reasons following: p>
1. The generator is overloaded, causing the charging current and voltage to exceed the rated value.
2. The power factor of the load is too low. Adjust the load so that the excitation current does not exceed the rated value.
3. Speed is too low, adjust speed to rated value.
4. There is a partial short in a generator winding. Check for the short and correct or replace the coil.
5. If the vent duct is blocked, remove the obstruction, disassemble the motor and carefully blow out each air duct.
As ambient atmospheric pressure decreases, temperature increases and humidity increaseslative increases, the dry air drawn into the cylinder of the diesel engine will decrease and the power of the diesel engine will decrease. the power of the diesel engine will increase. Then, when the ambient temperature is too low, when the temperature of the cooling water in the water tank is too low, the temperature of the lubricating oil will drop accordingly. larger when the temperature is lower, and its fluidity will become worse. This will not only increase the wear of diesel generator set parts, but also cause the increased resistance to movement and increase the mechanical power loss and efficiency. the power of the diesel generator set will decrease
