To optimise your electrical network
For Power Distribution
Utilities
the market place
is becoming
increasingly
competitive.
There is
a challenge to improve
profitability whilst
simultaneously
providing
higher quality.
How can you address
this paradox?
in terms of safety, profitability, availability
What does
network automation provide?
b Network management provides higher levels of service.
b Having a major positive impact on both capital expenditure (CAPEX)
and operational expenditure (OPEX), it allows you to face your market challenges in
the best position.
b Monitoring and control of your network follows your global policy
of the electrical network equipment program such as retrofit, expansion, network
equipment upgrade, operation (local or remote, manned or unmanned substation...),
maintenance...
One of your main needs
to cut implementation and operating costs
It is now known from market feedback that:
b the MV distribution network has to face very frequent
evolution - flexible solutions are mandatory
b implementation duration may affect return on investment
performance - the maximum has to be tested in factory
b maintenance issue may be a difficult issue if not well addressed at
the design level
b the simplest may be the most efficient.
What are the expected benefits
from Easergy range products?
b Increasing customer service and satisfaction
b Improving economic performance
b Mastering investments (past and future).
b Reduce outage time
v Easergy Fault Passage Indicators identify certainly the network faulty section
v Easergy control unit actuate network switchgear from remote control center.
b Optimised operation and use of the network
v Easergy products provide accurate information on outages and significantly simplify
and reduce the field crew effort required to clear faults
v Easergy products dramatically reduce the time to localise faults and to re-configure
the network
v intelligent devices of Easergy products offer assume optimised maintenance procedure
thanks to self test features and comprehensive maintenance function
v Easergy products provide an efficient access to new communication system
(GSM, Internet…).
b Reduced pressure on budget by mastered costs and investments
v Easergy modular and highly integrated devices reduces dramatically installation and
commisioning costs
v with Easergy offer, thanks to a comprehensive modular range, just invest what is
really accessible and get immediate cash. Then proceed to
relevant expansion when budget is available.

Advantages
b Highest availability of supply due to
the reliability of the product, the high level
of manufacturing testing.
b Simple commissioning, operation
and maintenance.
b Enable you to cut purchase, commissioning,
operation and maintenance costs; use it as a key
factor to reduce outage times, to optimize field crew
management…
