Additional Revenue Metering Security
To meet government regulations and utility security requirements, the revenue
meter incorporates additional security systems:
a hardware-locked security system that prevents modification of revenue
quantities after the meter is sealed.
a traditional anti-tamper mechanical seal on the meter base unit.
Hardware Lock Security Option
The hardware-locked security feature is an ordering option for some ION 8000
series meters. This hardware lock is factory set; to make configuration changes to
billing parameters on a hardware-locked meter, you must first place the meter in
TEST mode. The TEST mode button is located under the anti-tamper sealed outer
cover. This button cannot be activated remotely with a Hardware Lock meter.
The Hardware Lock Option can be combined with Advanced Security and the
Front Panel Security to offer the highest level of security. Once the TEST button is
activated, all rules above for Advanced and Standard Security still apply. When
the TEST Button is not activated, no changes to the locked parameters can be made.
Those parameters that are not locked are outside the revenue metering space.
However if Advanced Security and Front Panel Security are enabled, the unlocked
portion of the meter is secured by the rules for Advanced and Standard Security.
In certain countries the meter is no longer revenue certified if the hardware lock is
broken.
Typical values that are protected include:
kWh, kVARh, kVAh delivered, received, del-rec, del+rec.
kW, kVAR, kVA Thermal and Sliding Window demand min and max values.
Digital Outputs controlling the energy pulsing applications.
All Power system settings, including PT and CT ratios.
