Power electronics is a technology that deals with the conversion and control of electrical power with high-efficiency switching mode electronic devices for a wide range of applications.
The selection and use of flammable gas detectors. Calibration gases. 45 Ideally, the gas to be measured should be used to calibrate the gas detector. Calibration of fixed and portable gas detectors is normally done using a calibrated. gas mixture from a cylinder, supplied by a gas company.
