Generator supporting system
I. Function of Capacitor Compensation Cabinet It is used to compensate for the reactive current of the generator, reduce the working load of the generator, increase the available capacity of the generator, and reduce the electricity consumption of the factory, save industrial electricity, and imp...Read more -
Principle of Diesel Generator
The diesel engine drives the generator to operate, converting the energy of diesel into electrical energy. Inside the diesel engine cylinder, the clean air filtered by the air filter mixes fully with the high-pressure atomized diesel sprayed by the fuel injector. Under the compression of the pis...Read more -
The structure and working principle of the generator
A generator is usually composed of components such as the stator, rotor, end cover, frame and bearings. The stator is made up of the frame, stator core, winding coils, and other structural components that fix these parts. The rotor is composed of the rotor core (with magnetic扼， magnetic ...Read more -
Generator Overview
Electric energy is one of the main energy sources in modern society. A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbines, steam turbines, diesel engines, or other power machinery, and converts the energy from water flow, ai...Read more -

The inspection method for the insulation of the generator rotor and the handling method for the decrease in resistance
Inspection methods for rotor insulation Inspection method after shutdown: Use a 1000-volt multimeter to test the insulation between the rotor and the ground. When the insulation resistance is lower than 2 MΩ, it should be dealt with. Inspection method during operation: During operation of...Read more -
The main reasons for the reduction of the insulation of the generator rotor
The main reasons for the reduction of the insulation of the generator rotor 1.1 The rotor’s insulation resistance drops below the allowable value due to moisture absorption. This can occur if the generator is shut down for a long period, or if the environment is humid for other reasons. &n...Read more -
