Electrical Grid Monitoring (EGM) Inc.

EGM’s advanced grid monitoring solution is based on a suite of 3rd Generation
sensors that combine fault detection and current measurement capabilities found in
earlier line sensors with precision voltage measurement, advanced physical
environment measurements, and a secure communications network to provide the
industry’s first holistically designed grid monitoring solution that accurately locates
problems across the Distribution network.

EGM sensors include the MSU-X for low-amperage lines and the MSU-1 for self-powered overhead lines. Contact EGM.net for all sensors available for Distribution networks.

Real-Time, All the Time
Monitoring, and ultimately managing, a diverse energy mix at the edge of the grid will
require more than intermittent measurements and involves more than just fault
detection. Supporting renewables and EVs, and understanding the electrical effects
of that equipment, requires real-time, all-the-time monitoring of more than just
current but many precise, time-synchronized electrical parameters such as voltage,
phase angle, power factor and frequency.
Improving ADMS with Advanced Analytics
Operational applications such as ADMS/DMS/OMS will benefit from accurate, timely
data captured from many points on the network. Specifically, Fault Location, Isolation
and Service Restoration (FLISR), Distribution Power flow (DPF), State Estimation,
VVO and Outage Management (OMS) will benefit from real-time precision electrical
data provided by Meta-Alert sensors and the alerts and notifications available from
Meta-Alert advanced analytics.
What Makes EGM
Different?
Real-time, accurate data is
so crucial to so many
operational applications that,
today, utilities are forced to
rely on “estimates” or
derived values. We feel it
does not make sense to
provide sensors for
distribution and ignore
transmission, or provide
sensors for overhead and
disregard underground, or
provide only current-related
data when accurate voltage
related data is so vital. At
EGM, we want to help our
utility customers improve
Grid Operations from the
point of Generation to the
consumer’s house… and
everywhere in between.
 

Data Security
The EGM system is a fully secured solution from gathering data by the sensors,
through secure communications from the field, and ultimately to the presentation
of information to the user. Our security strategy is guided by NIST’s Cybersecurity
Framework Smart Grid Profile (Tech Note 2051), which provides the structure for the
design, development, testing, and documentation of the EGM solution.

Operating Conditions and Conductor Health
EGM’s Meta-Alert system provides near real-time operating characteristics such as
Power (MW, MVA, MVAR), conductor temp, and EMF emissions as well as fault
detection and vegetation contact. Meta-Alert warns of potentially dangerous
situations (ice accretion, galloping) and tracks historical overload events where
cable temperatures have exceeded limits and may have resulted in annealing.

Dynamic Line Ratings (DLR)
Dynamic Line Rating is the calculation of a transmission line’s actual current carrying
capacity. DLR is presented in real time but also as a set of forecasted values. DLR is
becoming increasingly important as utilities face an increased amount of renewables
on the Grid and chronic congestion in specific locations.
