Fault inspection of the motor(2)
Fuse Blown or Thermal Relay Tripped During Startup Fault Inspection Steps Check if the fuse rating is appropriate. If it is too small, replace it with a suitable one and test again. If the fuse continues to blow, inspect whether the drive belt is too tight or the driven load is excessive, check ...Read more -
Fault inspection of the motor(1)
For the troubleshooting of motor faults, various materials present a wide range of methods. From the perspective of combining theory with practice, the following specific analysis is conducted. 1. The motor fails to start. 1) The motor does not rotate and there is no sound. The reason is that th...Read more -
Prohibited Operating Procedures for Using Diesel Generators in Winter
The temperature in winter is relatively low, and there are often some minor problems when starting diesel generators. Some people often adopt incorrect methods, which can damage the diesel engine. Here are six methods that are not advisable for starting diesel engines in winter at low temperature...Read more -
Operation regulations for the two-point grounding protection device of the excitation circuit
1. The two-point grounding protection device for the stator and rotor excitation circuits is used to monitor the situation where the rotor circuit of the running generator has a permanent metallic grounding. Once the second point of grounding occurs, a signal will be generated or the generator sw...Read more -

Basic Faults of Generators 1. Common Faults Occurring During Generator Operation The following are some common faults that occur during the normal operation of a generator: (1) Interphase Short Circuit of Stator Winding. If an interphase short circuit occurs in the stator winding of a generator ...Read more -
Types of generators
At present, electricity 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 generated ...Read more -
Structural features 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 pole w...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 -

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 operating conditions of the three excitation systems
The generator of Phase 1 has been in normal operation since its commissioning in 1984. The brushless excitation system has been running smoothly and the automatic excitation regulator has been frequently engaged and requires minimal maintenance. The generator of Phase 2 has experienced multiple ...Read more -
The control section of the excitation system
The automatic excitation regulator for the first phase consists of a silicon-controlled rectifier power unit, a phase-shift triggering unit, a DC amplification unit, a voltage feedback unit, a deviation control unit, a DC power supply unit, and a power supply monitoring unit. The rectifier power ...Read more -
Generator knowledge: What are the rated parameters of synchronous generators
The main rated electrical parameters of a synchronous generator are: (1) Rated power (pe) refers to the rated active power that the generator can output under rated operating conditions, measured in kilowatts (kW) or megawatts (MW). (2) Rated voltage (Ue) refers to the line voltage of the genera...Read more
