Abstract
Systems and methods for providing notifications to monitoring systems that are remotely located from a well upon failure of a surge suppressor in a drive system for equipment used in the operation of the well. In one embodiment, an ESP system is installed in a well. A VSD having a surge suppressor is coupled between a power source and the ESP system. The surge suppressor is monitored to detect a failure of its surge suppression capabilities. In response to detecting a failure, a notification is provided to a monitoring system that is located remotely from the well. The notifications may be provided via phone call, email, text message or other means. The surge suppressor may also provide a local indication of the failure. The VSD may be configured to continue operation despite the failure of the surge suppression capability.
