High and Medium Voltage











Generators



KEMA has always been the partner for utilities, industry and manufacturers in activities concerning power generators. This includes:   
  • Acceptance testing              (at manufacturers' works)   
  • Periodic testing in the power plant 
  • Consulting and advice 
  • Failure analysis   



Electrical tests on stator

On site we can perform tests on the stator, such as:
  • Measurement of the insulation resistance of the stator and the polarization index  
  • Measurement of the capacitance and dielectric losses (tan delta) 
  • Measurement of Partial Discharges 
  • Voltage test



Customers also require tests on the rotor, such as insulation resistance and FRA measure-ment. 
 
 
 
In addition to these services, KEMA offers:
  • Thermographic monitoring of the stator core during the magnetization test  
  • Supply of power and measuring facilities, all included, for specific testing
