    How to calculate manually Battery AH rating

    What you need is a load bank that can be loaded with 68A for 10hours. Measure the discharge current in regular intervals of maybe 15min. Calculate your average ampere multiplied by the time in hours. Discharge until you have discharged 680Ah if you want to prove that the Battery bank has more...

    exciter Peak Rating

    Hi Not sure if I understand you correctly. However if you run your Generator with 110% Rated Voltage you will supply VAR to the Grid. Assuming that you are connected to a grid off course and that the Grid voltage is less than 110% rated. So you are right. Overexciting a Generator on Grid will...

    Potencial Transformer issue

    As dpc above mentioned. You need to know your actual burden connected to the PT. If it is just used for relaying your burden would not be very high. You can calculate your burden by multiplying your PT secondary voltage and the current provided by your PT. Burden = Volt x Amps [VA]

To install the correct data models however is a big pain in the a**. The Studio Software allows you to connect to different Relay types without...
