A Sunday evening, 8.30pm, a cement factory in Ireland suddenly came to a complete stop. Unipower representative Garrett Kelly was called in to investigate.
8 years earlier the factory had installed PQ Secure system and a UP 2210 for post-processing of data. Meter was still logging as it should and after downloading data, investigation showed an arcing earth fault causing the interruption.
Yet more important was that the data showed that the shutdown could have been avoided.
PQ Secure is designed to be an early-warning system so after a system upgrade PQ Secure is now in use documenting as before and at the same time alerting for abnormal values and disturbances. More UP 2210s have also been added to strategic connections.
