<p>The method involves measuring a different between a chassis potential and a reference potential using a chassis voltage measuring device. A difference between an intermediate potential and a reference potential at an intermediate point of an insulation intermediate plane is measured using an intermediate voltage measuring device. An intermediate voltage value is compared with a preset value by a microprocessor. An alarm signal is generated by the microprocessor when the voltage value exceeds the preset value. An independent claim is also included for a device for detecting and monitoring an over voltage in a trolley bus.</p> |
