S780 Overhead Line Monitoring
S780 is a self contained unit built for direct field
installation. The solution is designed for monitoring
one feeder but can be easily upgraded to multiple
feeders if needed.
S780 standard configuration has no DI/DO but can be
combined with any other Landis+Gyr’s modules for
additional functionalities, such as adding digital
inputs/outputs, upgrading to multiple MV feeders or
even adding LV supervision in combination with the
MV supervision if need be.

Retrofit Distribution Automation

Enexis – Drivers for Distribution Automation
 Improve the quality of power distribution to
reduce frequency and duration of power
outages and radically decrease utility’s SAIDI
figures
 To deploy a retrofit solution in existing and new
substations.
 The automation solution had to fit 20% of the
substation variations which covered 80% of
utility’s network installations.
 To reduce installation costs by deploying a
standardized distribution automation solution,
both during the installation phase but more
importantly, during the replacement phase if
need be.
24

Enexis – customer experience
 Over 700 units rolled out
 Very little interaction with installers was
required in the field as everything could be
pre-configured. Installation did not require a
laptop.
 Significant outage reduction has been
achieved. Customer Minutes Lost (CML)
reduced from 87+ minutes to 3–5 minutes,
reaching almost 60% (instead of expected
40%).
 Grids are more meshed than originally
expected.
 Based on this experience the utility is able to
update its Distribution Automation strategy.
25
 Low Total Cost of Ownership of the solution
 Remote upgradability for SCADA protocols
 Remote firmware capabilities to roll out security
updates based on external security revision

MV/LV Monitoring & Control

DONG energy - Drivers
 DONG energy was one of the first utilities to
start implementation of the smart grid plan back
in 2000. Their goal was to create a MV/LV
Monitoring and Control Solution for their
distribution network.
 Primary goal was to deploy a modular retrofit
solution to fit DONG energy’s large variety of
substations, some being 100 years old and
others being brand new.
 Second objective was to locate faults faster
(earth faults and short circuit) to be able to
reduce SAIDI, which required automation
capabilities.
27

DONG energy – customer experience
 Over 300 units rolled out (5% of substations
covered with automation and 3rd Generation fault
detectors)
 Significant outage reduction has been achieved.
Customer Minutes Lost (CML) reduced from 35+
minutes to approximately 7 minutes.
 The system has been in operation for more than 10
years and is now used beyond fault detection, e.g.
for network planning.
