Why RMS ?

Ability to detect tamper events and outage occurrences. Remotely Connect/ disconnect power supply through

meter. Calculate transformer loading and sizing from interval

data 15 minute interval data gives accurate load information

for supply scheduling, switching operations, planning etc Monitor voltage at each premise to know conditions

when to operate capacitor switches or regulators Consistent and granular data for improved accuracy
