Providing insight into the quality of electricity
EMT720T meters register all Power Quality circumstances
“A year ago we were dealing with an inexplicable temporary malfunction of our thyristors. To ensure insight into the Power Quality during future errors, HyTEPS provided advice and supplied us with the SATEC EM720T meter. Currently we have – via the included software- full time insight into the quality of our electricity, both real-time and in the past.” - Patrick Emmers, Reliability Engineer E&I at Nyrstar

Inexplicable loss of thyristors
Nyrstar is the only zinc producer in the Netherlands and produces circa 290,000 tons of high-quality zinc annually.
“When producing zinc, we use rectifiers with thyristors and diodes. A year ago we had to deal with inexplicable temporary failure of our rectifiers with thyristors. During extensive research into the cause of the failure, the question about the quality of our electricity came up. When the term Power Quality was mentioned, we immediately approached HyTEPS, our regular supplier in the field of Power Quality.”
Understanding Power Quality with EM720T
“In consultation with HyTEPS we have chosen for the EM720T. This is the fastest and most advanced meter that registers all possible Power Quality events, including transients, surges, dips, flicker and harmonics.
HyTEPS delivered four of these meters, one for each of our 10 KV power lines. We configured the meters and associated software in collaboration with HyTEPS.”
Real time insight and history
“Whenever we experience a failure of equipment such as frequency converters, power supplies or the thyristors, we are able to check the status of the Power Quality immediately - real-time - but also in the past. This reduces our search area concerning the cause of the failure.
In addition, we are able to provide insight into long-term trends.“
