Smart Street Light Solution

Objective

Remote operation and maintenance of individual street lamp pole by wireless smart meter technology with Energy cost saving mechanism

Meter measures Active, Reactive, Apparent energy on 1 phase 2 wire system,
Output LED are placed on side panel to indicate Power ON and Load ON/OFF status,
Electronics are placed inside IP65 based enclosure,
Wireless Xbee Communication can be done between Co-ordinator (Master) and Meter,
Load relay is provided to disconnect or connect load according to the site conditions via GPRS communication
Specifically meant for lighting systems

Meter measures:

Active, Reactive and Apparent energies in all four quadrants in forward and reverse directions
Instantaneous parameters – phase wise voltages and currents, Power, Frequency, Rising Demand, Maximum Demand, Phase sequence, Power Factor, Date and Time.
All the electronics are enclosed in IP65 based enclosure and so no external EARTHING TERMINAL is required,
RTC with battery backup is used for time keeping and has a calendar of 100 years,
Meter data will be collected via RS485 communication and in turn it is transmitted to web page via GPRS communication
Three separate load relays are connected which can be used to connect or disconnect the load. This can done individual phase and all the three phase.
