<P>Hello everybody,</P><P> </P><P>I'm developing a multisite PME with ION7650, the customer is asking me a series of parameters but I haven't found them among the native measurements of the meter or in the standard graphic in PME.</P><P> </P><P>The parameters are:</P><P>- Displacement power factor (I haven't found it)</P><P>- Average PF (I haven't found it)</P><P>- Working time of the meter (I haven't found it)</P><P> </P><P> </P><P>I would like to know if I have to develop frameworks in designer to have these measurement or if any of them is already present natively in the meter.</P><P> </P><P>In addition, I saw:</P><P>- Crest factor of I and V : I saw they are available, but they're not present in the standard graphic</P><P>- Harmonics until the 63rd: I saw that in the standard graphic harmonics are shown up to the 15th, I need to see more.</P><P> </P><P>Should I modify the standard graphics or is there any quicker way to have these parameters displayed?</P><P> </P><P>Thanks in advance to whoever's gonna help me!</P>Thu, 20 Dec 2018 16:33:57 GMThttps://community.exchange.se.com/t5/Metering-Power-Quality/ION7650/m-p/157600#M3316sesa261168_brid2018-12-20T16:33:57ZRe: ION7650

<P>I do not have the exact framework, but in older ION7650 meters (before V350), there was the "Power Availability Framework".</P><P>Looking at the ION Device Template Reference, it may be possible to re-build this. I believe this framework was taken out becuase of processing space so it may need to be trimmed down or possibly other features removed.</P><P><A href="https://www.schneider-electric.com/en/download/document/ION_Device_Template_Reference/" target="_blank">https://www.schneider-electric.com/en/download/document/ION_Device_Template_Reference/</A></P>Tue, 05 Mar 2019 01:09:56 GMThttps://community.exchange.se.com/t5/Metering-Power-Quality/ION7650/m-p/161250#M3366Charles_Murison2019-03-05T01:09:56ZRe: ION7650
