<div dir="ltr"><div dir="ltr"><div>Hi Sativa,</div><div><br></div><div>It sounds like you have a surge problem with the electric utility. Nothing kills a cleanroom operation faster than power problems. I am not sure what can be done about it up front. Installing a monitoring instrument on the power will help you quantify and describe your power issue. <br></div><div><br></div><div>I have been using an instrument called the PQube from Power Standards Lab. <a href="https://www.powerstandards.com/">https://www.powerstandards.com/</a>. It monitors, records data. If you get data from that maybe some corrections can be made with the transformers serving your facility or other things. I don't seem to have problems as serious as yours but it's nice to know when a sag trips off several systems instead of just guessing at it. <br></div><div><br></div><div>Let me know if you have more questions,</div><div>Gary</div><div><br></div><div><div><div dir="ltr" class="gmail_signature"><div><font size="2" face="Arial">Gary Olin<br>Equipment
