APPARATUS FOR MONITORING DISCHARGE PROCESSES IN A CONDUCTOR OF A MEDIUM-VOLTAGE OR HIGH-VOLTAGE SYSTEM |
摘要 |
<p>An apparatus monitors discharge processes in a conductor of a medium-voltage system or a high-voltage system. The apparatus contains at least one transformer which is suitable for detecting a current flowing in the conductor. The at least one transformer is connected to a device for monitoring the discharge process. In order to be able to monitor even very short discharge processes in an energy-saving manner, a release and at least one storage circuit are arranged between the transformer and the monitoring device. When a threshold current flowing in the conductor is exceeded, the release switches the monitoring device from a passive mode that is not suitable for monitoring into an active mode that is suitable for monitoring. The storage circuit stores the discharge current to be monitored and/or recorded by the monitoring device.</p> |
