General description
Kamstrup 162M and 382M are a generation of directly connected electricity meters for the measurement and
registration of electrical energy. The meters are full-electronic without movable parts. Thus, energy registration is
not affected by shock and impact during transportation and mounting. Furthermore, measurements are correct,
no matter the physical mounting direction. Using shunt as measuring principle, it is possible to obtain a good
linearity, a very large dynamic area and immunity to magnetism and DC currents.
The easily readable display scrolls automatically between readings, or readings can be changed manually by the
consumer activating a push button. The required display readings as well as their order are configurable. In
addition to being read from the display, data can be collected via the optical output or from the module area by
means of a suitable communication module. The unique module area also permits external monitoring of tariffs,
pulse inputs and outputs, and configuration as well as connection of AMR and AMM modules.
From the factory, the meter can be configured to measure both imported and exported energy. The meters are
constructed with independent and galvanically separated measuring systems (the number of measuring systems
depends on the meter type). This ensures a correct measurement irrespective of how many and which
measurement systems are used. The energy registration is saved in the integral data logger, which ensures good
data history.
The meter construction makes it immune to magnetic influence, and the measuring accuracy will not be
influenced by magnetism.
It is possible to supply the meter with battery backup for the integrated RTC (Real Time Clock) used for tariff
control and time stamping of data and events.
The tariff control permits up to 8 tariffs. The tariffs can be managed by the internal clock (RTC) on the basis of
preprogrammed time tables. The tariff shifts can also be effected by summer time/standard time and holidays.
The meter is configurable and can be supplied from the factory with required functions. This ensures a minimum
of configuration during installation. Furthermore, the meter can be configured to verification mode, which
improves the resolutions of the energy indications, thereby reducing the duration of test and verification.
The meter is approved according to current electricity meter standards.
Kamstrup electricity meters are supported by a Kamstrup configuration tool called METERTOOL.
2.1
Terms
Integration period:
The integration period is the length of time over which the power is averaged in order
to find e.g. the peak power. For instance, it can be 15 min.
Load profile logger:
A logger that contains a series of energy values A+, A-, R+, R- depending on meter type.
The interval between each values is defined by the integration period. As default the
logger contains the last 4 months of data.
Debiting period:
The debiting period is a configurable length of time between each debiting entries
where the value of a number of predefined meter regsiters are logged. Usually the
debiting period is 1 month.
Debiting logger:
Contains a series of predefined meter registers that are logged with a customer-
specific time interval defined as the debiting period. The depth of the logger is 36
entries.
