VCM sensors play a critical role in getting more capacity and life out of our power transformers. There are six crucial parameters we need to check to ensure the health of a power transformer: hydrogen level, moisture level, oil temperature, oil level, pressure, and short circuit. We have embedded sensors for each one of these parameters. Unlike other external transformer sensors and monitors that have set points to trip or alarm, our sensors are embedded and integrated to furnish continuous data on these parameters to observe the trend and fix the problem before it is out of control. The data is stored for the life of transformer. The sensors themselves are solid-state and designed to last as long as the projected life of the transformer. A partnership and collaboration between the customer and supplier regarding the proper preventive actions on the readings from this monitor will ensure the extended life of a power transformer.
