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 -

How to identify and handle the situation when the oil pressure is too high
1. Phenomenon When the engine is operating, the oil pressure gauge indicates an excessively high oil pressure value that exceeds the specified limit. 2. Cause Analysis From the principle that the lubrication system generates pressure by the oil pump, it can be known that the lubricating oil in t...Read more -
A Brief Discussion on the Generator Grid Connection Breaker System
Power plants often use generators as backup power sources to cope with power outages in the grid, failures of power supply equipment, and equipment maintenance. When a power outage occurs, the generator should automatically start within a few seconds to supply power to the feeder cabinet and elec...Read more
