Different Types of Sensors and their Working· The sensor can be defined as a device which can be used to sense/detect the physical quantity like force, pressure, strain, light etc and then convert it into desired output like the electrical signal to measure the applied physical quantity. In few cases, a sensor alone may not be sufficient to analyze the obtained signal.
8DA10-8DB10 | Medium-voltage switchgear - Siemens USA GIS is approximately 1/5 th the size of conventional air-insulated switchgear depending upon the voltage rating and is suitable for systems where small size, arc resistance, environmental immunity and/or reduced maintenance needs are important. Watch the video below to learn more about medium-voltage, gas-insulated, arc-resistant switchgear.
Voltage Converters and Transformers | 220-Electronics built in technology will turn the transformer off when connected to a electrical device that is too powerful for the transformer. When this triggers you can simply reset the transformer on models that are larger than 500 watts size, while on 500 watts and smaller a fuse needs to be replaced.
