6.12. Fraud protection measures
The meter incorporates the following features designed to prevent tampering and/or assist in the detection of
attempted fraud:
Feature Description
Anti-fraud measuring mode The meter may be configured to register energy with an anti-fraud
algorithm.
Meter and terminal seals The meter body and terminal cover may be independently sealed with
conventional wire or plastic seals.
Protected voltage links Access to the links requires removal of the sealed terminal cover.
Monitoring Anti-tamper events, for example:
current reversal or cross-phasing
zero sequence U and I
duration without internal consumption above a threshold
excess current
Recorded as date/time stamped events, which can be read from the
meter.
Reverse energy Recorded as date/time stamped events, which can be read from the
meter.
Indication provided by an annunciator in the LCD.
Configurations When any aspect of the meter is programmed, the meter records the
number of objects configured as a date/time stamped event.
Typical fraud-related parameters include:
Calendar reprogramming (seasons, day profiles, index)
CT/VT transformer ratio reprogramming
Indication of meter cover and/or
terminal cover removal (optional)
Recorded as date/time stamped events:
start date of cover opening
duration
number of cover opening events
The detection of meter cover removal remains active during power failure
events (one opening is counted regardless of how many occurred). The
detection of terminal cover removal is not active during a power failure.
Magnetic shielding The meter enclosure can be optionally fitted with an effective shielding
against external magnetic fields. (up to 1,2T).
Magnetic attack detection The meter is equipped with a magnetic field detector. This can be
configured to:
record the number of magnetic events
record the time/date and duration of the last 10 magnetic events
generate a non-fatal alarm and light an annunciator in the LCD
increment specific energy registers during the magnetic event
