Dual Supply Meter.
ProMeter can be used for electricity billing where more than one source of power is
available like Generator. Te benefit of dual supply is that different tariff for both the
supplies can be programmed separately. Meter automatically detects the supply by
sensing the auxiliary terminals available. Meter stores individual records for both the
Mains and
Generator supply separately. It deducts the balance corresponding to the
tariff programmed.
Over-Load Cutoff.
Over load condition is generated when the load is more than the sanctioned load. Te
meter shall have 5 steps of over load handling. Each step shall have the following
settings:
• Duration for which the over load is allowed
• Duration for which the meter should cut the load
If the over load condition is not removed even after the 5 steps than the over load can
only be reset manually by reset switch. These limit for over load as well as the settings
in the five steps is programmable through ProMeterSoft.
Monthly Consumption & Demand.
Te meter stores the monthly consumption history for energy consumption and
Maximum demand for last six months along with the date and time of maximum
demand occurrence.
Happy Hours / Holidays.
To prevent the supply cut in the nights and holidays ProMeter has a feature of
programming the happy hours and holidays. Happy hours could be programmed as
Start time and End time whereas up to 30 annual holidays along with weekly holidays
can also be programmed. These are the times when meter won’t cut the supply even if
balance is reduced to zero / below emergency credit.
