Note: For tamper logics, following points shell be taken in consideration
1. During Neutral disturbance tamper, All voltage related tampers (i.e. Voltage Failure, Voltage Unbalance,
High Voltage & Low Voltage) shall not logged.
2. During High Voltage & Low Voltage tampers Voltage unbalance tamper shall not logged.
3. During Voltage failure Tamper, Voltage Unbalance & Low Voltage tamper shall not logged.
4. During current failure Tamper, Current Unbalance tampers shall not logged.
5. During power failure duration, if any tampers persisting, those tampers shall not get recovered until it meets
the logic for restoration and duration of respective tamper shall be from occurrence of that tamper irrespective
of power failure duration.
6. For tamper events logging, snap shot data i.e. instantaneous parameters, active energy register reading
(Total kwh) & date & time should be corresponds to starting of occurrence and starting of restoration.
7. Snap shot of date and time should be available for occurrences and restorations of events.
8. Low PF tamper feature is not required in display as well as memory. Instead of that, MD reset counts may be
added in display-1 mode.
