Bad Data Quality limit in logs
Sir, I have a ques to ask. I have created logs with 1 direct & 2 Hierarhical logs. "bad data quality limit" for direct log has been 100% while for Hierarhical logs it is 0% (i guess by default it comes.)
My question is what is the purpose of setting "bad data quality limit". Because we noticed when a feeder is in shutdown condition its MFM (from which log values are coming), for direct log it shows the KWh value lets say 99999 with dataquality as bad. however for Hierarhical logs it shows 0 with dataquality as bad.
Can you provide some explaination for this behaviour of logs
Hierarchal logs are calculating their value from x number of values from the level before.
If you eg are caclulating average from 10 values, then the "bad data quality limit" defines how many values can be bad from the 10 and still calculate the average value. If you eg set "bad data quality limit" to 70, then it means in this case three values can be bad but still an average is calculated, using the seven good values.
