Abstract
An embodiment of the invention provides a method for monitoring electrical characteristic on an electronic circuit board. This electrical characteristic can be voltage or current. The electrical characteristic is measured at a first location. The first location is at a high voltage called primary potential. The electrical characteristic is converted to a proportional frequency. The frequency is sent through an isolation circuit to a second location for monitoring. The second location is at a low voltage called secondary potential. The frequency is provided as input to an environment monitoring circuit at the second location.
