  • Research of the vibration characteristics in GIS Disconnector

    Sep 13, 2018 · If the ratio of 200Hz is larger than 0.2 and the ratio of 50Hz is between 0.1 and 0.3, it can be convinced that the GIS disconnector has a loose contact. If the ratio of 200Hz is larger than 0.5 and the ratio of 50Hz is larger than 0.2, it can be convinced that there is serious mechanical defect in the GIS disconnector.

  • Why we use 50Hz, 60Hz or 400Hz frequency? | GoHz.com

    Jan 12, 2017 · 50Hz generator synchronous speed is 3000rpm, if the frequency is 100Hz, then the synchronous speed will be 6000rpm. Such a high speed will bring a lot of troubles to manufacture the generators, especially the rotor surface speed is too fast which will limit the generator capacity greatly.

  • biopotential - 50hz noise removal from ECG power supply

    If the 50 Hz is on the power supply like you say it needs decoupling. First the power supply itself. A good regulator won't have a 50 Hz ripple on its output, so maybe the smoothing capacitors on the inputs are too small. (On second thought that ripple should be 100 Hz. A defective diode in the rectifier bridge would explain both 50 Hz and a too high ripple.
