Smart Devices
NES smart meters are critical devices within the NES System. They not only provide traditional electricity meter measurement functionality, but they also serve as advance power quality sensors for the distribution grid. NES smart meters meet the future market and regulatory needs of a utility by incorporating a rich set of features including prepay, multi-tariff abilities, remote firmware updates, remote connect and reconnect, tamper and outage detection, hardware extensibility, direct relay control, software-configurable service levels, and load factor monitoring. NES Smart Meters can be updated with new pricing, quality of service, energy management, and monitoring and control services even after they’ve been fully deployed.
Single Phase Smart Meter (PLC Mode)
Millions of meters deployed with 20 year service life. Each meter acts as repeater to reach other meters and establish a power line mesh network that shows the real topology of the low-voltage distribution System.
Forward, reverse, net active energy, kvarh import/export, and four-quadrant kvarh measurements enable customer micro-generation sources and power quality monitoring. Tampering attempts are detected on cover removal and magnetic field presence. All events are detected and logged – even during power failures – and then securely communicated in a timely manner. Energy measuring technology is highly resistant to DC magnetic fields.
Single Phase Smart Meter (Cellular Mode)
This is an is an ideal fit for Advanced Metering Infrastructure (AMI) systems intended for Pre-payment features, load management, multi-rate / Time-of-Use and anti-theft metering of residential and light commercial consumers with single-phase service connections. Measures, collects, analyzes, controls energy usage and communicates with Head End System either on request or on a schedule. This gives unparalleled end-to-end visibility to the utilities into their distribution networks. Meets Indian BIS standards 16444 for Indian market.
3 Phase Smart Meter ( PLC Mode)
DLMS compliant for Indian Market with Enhanced Security, Optional UC3 Compliant Disconnect Switch Larger Memory for More Data Storage. Secure remote firmware upgrades. MEP Connections and Flexible I/O options. Cutting Edge Host Processor for Future Smart Grid Application Expansion. Innovative and Customer Friendly Mechanical Design. Power quality measurements include: voltage, current, frequency, power factor, Total Harmonic Distortion (THD). 4×16 channels of load profile data; each with independent configuration of interval, size and collection settings. Optional dual relays (latching or solid state). H1 HAN port for home network connection.

3 Phase Smart Meter (GPRS Module)
This is an is an ideal fit for Advanced Metering Infrastructure (AMI) systems intended for Pre-payment features, load management, multi-rate / Time-of-Use and anti-theft metering of residential and light commercial consumers with three-phase service connections. Measures, collects, analyzes, controls energy usage and communicates with Head End System either on request or on a schedule. This gives unparalleled end-to-end visibility to the utilities into their distribution networks. Meets Indian BIS standards 16444 for Indian market.
FAQ
Yes, both type of smart meters i.e. PLC mode and Cellular mode are meeting the requirements, which are there under BIS 16444 for smart meters and required as per RDSS Scheme for Utilities.
Average life of these smart meters is around 20 years, however warranty period is 5.5 years from the date of shipment, which can be extended for maximum 8 years.
NES Technologies, PLC smart Meters, works as repeaters in a PLC MESH type architecture. PLC MESH is one of the very powerful feature of PLC based AMI, which Utilities can use to have a self-owned reliable AMI Network with almost zero-maintenance cost, and this can connect smart meters even in not much well-managed electrical networks or where wireless connectivity has challenges. The number of PLC Smart Meters per DCU depends on the meter density on DT and many other factors however it can be upto 500-600 per DT.
For urban areas like Delhi, Mumbai, Gurugram, Noida, Bangalore, Pune, Ahmedabad, Tier-1, Tier-2 and other metro cities, having high consumer density and better managed electrical infrastructure, PLC mode smart meters are much better option from any other mode meters, considering the high level of communication reliability, and almost negligible maintenance cost.
Yes, we export DLMS complaint PLC Mode and Cellular mode in a hybrid manner solution to Utilities outside India also.
