Q: So, what sensors do you imbed in your new power transformers? How will these sensors play a role in us getting more capacity and more life out of transformers?
There are five 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 imbedded sensors for each one of these parameters. Unlike other transformer external sensors/monitors that have set points to trip or alarm, our sensors are imbedded 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 a transformer. A partnership and collaboration between the customer and a supplier regarding the proper preventive actions on the readings from this monitor will ensure extended life of a power transformer.
