Compensation of simple fiberoptic faraday effect sensors |
| abstract |
A monitoring system for detecting earth faults in an electrical power supply grid is disclosed. The system includes monitoring devices mounted in a number of monitoring locations. Each of the monitoring devices includes a detector for detecting the level of harmonics in the electrical power in a specific frequency range, a memory device for storing a harmonics reference value, a processor for comparing the level of harmonics with the reference level, and a communication device for transmitting an alarm provided the level of harmonics is above the reference level for a specific period of time. |
