Smart Grid Definition
4
Present Mode of Operation: “Transporting energy from major generation sources
using mostly non-renewable fuels to consumers who have limited knowledge of
their consumption, where outages affecting customers are largely unknown until
the customer alerts the network operator”
Smart Grid Proposition: “dynamic network for two way energy flows; linking
widely dispersed renewable energy sources and large energy sources; providing
more dynamic information to customers; facilitating customer choice about
energy source and level of consumption; and providing real-time information on
the performance of the network”

For every tampering connection,
the wire can be reversal
connected so that makes the total tampering
possibilities into double.
And our meter can totally protect against
42 kinds of tampering.
