Introduction | BIS for AC Static Smart Meters
India’s electricity sector is experiencing a massive transformation in terms of technology adoption. This is because there is a need for billing precision, greater focus on energy conservation, as well as transparency about electricity usage. A lot of electromechanical meters are being displaced by AC Static Smart Meters. However, as technology improves, it is essential to focus on aspects like consumer safety.
For controlling and implementing such meters, the Bureau of Indian Standards has developed IS 16444 Part 1 as an Indian Standard for AC static direct connected watt hour Class 1 and Class 2 smart meters. BIS for AC Static Smart Meters is not optional; rather, it is mandatory for manufacturing, importing, and supplying smart meters in India.
What Is BIS for AC Static Smart Meters (IS 16444 Part 1)?
BIS for AC Static Smart Meters for IS 16444 Part 1 is a conformity assessment procedure, and it is done to ensure that AC Static Smart Meters fulfill certain Indian specifications for:
- Measurement accuracy
- Electrical Safety
- Performance reliability
- Ecological resilience
- Communication compatibility
This certification is applicable for direct connected watt hour smart meters meant for residential, commercial, and light industrial applications. Such smart meters are an integral part of the Advanced Metering Infrastructure projects implemented by DISCOMs and Govt. utilities in India.If the smart meters are not BIS certified, they cannot be sold or imported into the country or installed and used in the electricity distribution networks in India.
Key Features of IS 16444 Part 1 Smart Meters
- Compliance for Accuracy Classes: Class 1 and Class 2 The standard requires strict accuracy to ensure accurate active energy measurements. This eliminates disputes in billing and promotes customer confidence.
- Smart Communication Capability IS 16444 Part 1 certified meters facilitate data communication modules for incorporation into the AMI system, which supports remote reading and monitoring.
- Tamper Detection and Event Logging Certified smart meters have enhanced levels of tamper detection functionality like neutral disturbance, magnetic interference, and opening of the cover.
- Environmental & Climatic Endurance Meters are checked for performance under high temperature, humidity, dust, and voltage variation. Meter testing is done under high temperature, humidity, dust, and voltage variation to ensure that
- Electrical Safety & EMC Compliance The standard provides that measuring meters will be protected from electrical shock, insulation breakdown, and electromagnetic interference.
