Photovoltaics

Low-loss transformers with high efficiency for open-air photovoltaic systems The expansion of renewable energies is imperative to make our energy supply CO 2-neutral. PV systems in particular play an essential role in the energy supply on and in buildings. The use of PV systems brings with it several new electrical aspects, especially in mains feedback and in the mains energy infeed. The possibility of the PV system interfering with its own operating main is remedied by mains transformers and isolating transformers as well as special filters. In the event of malfunction, the specialists at Bürkle + Schöck can detect and analyze them with special measuring devices and then develop suitable solutions. Here we have compiled some of our products and services for photovoltaics – we will certainly have the right solution for your individual requirement.

  • Mains transformers and isolating transformers
  • Low voltage transformers
  • Medium voltage transformers
  • EMC filters
  • passive filters and active filters
  • passive harmonic filters and active harmonic filters
  • Analysis of interference due to mains feedback
  • Measurements of mains quality

Increased power transmission in underground cables

Often large PV open-air systems are located apart from conventional construction areas and must be connected to the public mains over relatively large distances. In these cases, it helps to increase the mains voltage up to the infeed point by means of suitable transformers, for example, to 950 V, and to lower it again to 400 V at the infeed point by means of a transformer. Existing underground cables can thus transmit about 2.2 times the power, which rapidly makes the addition of remote photovoltaic systems profitable.
