A resistor-capacitor (RC) sensor circuit includes an integration capacitor configured to integrate a representative copy of a current that drives an electronic circuit line. The integration capacitor is configured to integrate over a first time period to generate a first representative voltage and over a second time period to generate a second representative voltage. The RC sensor circuit includes a sampling circuit coupled to the integration capacitor and configured to sample the first representative voltage and the second representative voltage. A ratio of the first sampled voltage and the second sampled voltage is indicative of an RC time constant of the electronic circuit line.

The subject disclosure relates to solutions for testing lighting systems and in particular, for verifying lighting system operability in the event of a power failure. A process of the disclosed technology can include steps for receiving an interrupt command, toggling an interrupt relay in response to the interrupt command, and measuring one or more lighting characteristics of the lighting array to determine if the second power supply can power the lighting array. Systems and machine-readable media are also provided.
