Professional plant protection

Protection technology

Protective devices are an essential component of human and plant protection and require regular testing in accordance with the guidelines stipulated in VDE 0105 and DGUV V3. Experienced service engineers from Kuhse possess the specialist know-how required for comprehensive and complex protection testing.

Kuhse conducts testing around the world on a wide range of protective devices produced by, for example, ABB, Alstom, GE, SEG, Siemens, Schneider and Woodward in low and medium voltage plants. The function, measuring accuracy and trigger times of protective devices are tested, in order to guarantee plant operators the maximum in reliability and safety for their plant.

Grid / generator analysis

High grid quality is a fundamental prerequisite for the failure-free operation of machines and plants. In the event of undesired protection releasing failures in the plant, Kuhse Service offers measurement and analysis of the grid quality in accordance with VDE/DIN specifications, as well as the logging and evaluation of generator voltages and currents. This results in a reduction in operating costs and service times, whilst also adding value for the plant operator.

The basic measurements at a glance:

  • Mains / generator harmonics
  • Flicker
  • Frequency stability
  • Short interruptions
  • Regulation behavior of the generator voltage regulator / PF regulator
