4 Frequently Asked Questions about “Wind turbine generator winding insulation measurement - RRR Renewable Projects (SA)”
What is the insulation system of a wind turbine generator?
The insulation system of a wind turbine generator is a critical component for reliable and long-lasting operation. The insulating system and materials used for these machines are basically the same as for conventional generators and must be carefully selected in order to meet very high specific requirements.
Do wind generators need rotor insulation testing?
However, testing rotor insulation is difficult and costly due to the limited accessibility of wind generators as they are installed at remote locations inside the nacelle. Therefore, remote and automated insulation testing can help improve the reliability and reduce maintenance cost of wind generators.
How do you measure a generator insulation resistance?
The only way to accurately measure the generator insulation resistance is to isolate the winding from all external equipment. to expedite routine maintenance checks readings can be taken at the earliest circuit breaker, but if a questionable reading is obtained the winding must be isolated and the test retaken.
Does rotor winding insulation fail in doubly-fed induction generators?
Abstract: Failure in the rotor winding insulation of doubly-fed induction generators (DFIG) is common due to the harsh environment and operating stresses. However, testing rotor insulation is difficult and costly due to the limited accessibility of wind generators as they are installed at remote locations inside the nacelle.
