Table 2: Energy Channel Registers
The pre-defined energy channels can be configured for display, billing, TOD, MD, Load Survey and Daily
Energy in line with purchase order requirements at the time of order.
Notes:
1) All the bi-directional energy registers (* marked) will have sign indication (‘-‘sign will be available for
negative value and no sign for positive value).
2) In ‘Apparent’ and ‘Net Active’ energy calculation, ‘Active’ energy can be either ‘fundamental’ or ‘total’.
This can be configured through the tariff tool. Both energies need to be of same type.
3) Single phase measurements (17-22) are supported by the 4 wire configuration.
For energy types 1-16:
These registers are continuously increased depending on the selected energy.
Example: Main Energy Register kWh (I) will show the total imported active energy logged till date.
Recording of all supported energy types is possible but only those energy types are logged into the memory
which is specified by the tariff file. An individual register is provided for all selected energy types. These register
are called Main Energy Registers. Whenever an individual energy type is generated / consumed, its value is
updated in the corresponding main energy register. These registers cannot be reset.
7.3 Instant values
Besides energy, the Prometer 100 can also measure instant values. Instant values are constantly changing
values such as current, voltage, power and harmonics. The instant values are updated every second. The
formulas and definitions used to calculate the values are presented in Appendix E: Calculation Principles on
page 61.
7.3.1 Overview
This table provides an overview of the instant values that can be read on the meter. Readings can be viewed
with M-Cubed, on the display and with other software that has implemented Prometer 100’s communication
protocol. Most instant values can be logged; for more information, see section Loggers on page 42.
