The DGA system by Hertzinno employs cutting-edge MEMS (Micro-Electro-Mechanical Systems) technology to analyze the gas content in transformer oil through photoacoustic spectroscopy. It supports the analysis of 9 types of gases and micro water content, offering high precision, maintenance-free operation, and long-term reliability.
The MEMS light source is equivalent to a chip level electrically modulated, which means the light source is programmable.
With MEMS electrical modulation technology, the system has a low power consumption, ensuring the long-term runing stability up to 10 years.
