The document describes an innovative technology called MetrySense-4000 that monitors power line insulator string contamination through partial discharge sensors. It detects contamination levels in real-time to help utilities reduce costs by washing insulators only where needed and avoiding power interruptions from flashovers. The system's wireless sensor units have a long battery life, low power use, and reliable connectivity to provide utilities with an overall vision of contamination levels on their transmission networks.

Ericsson Technology Review – Microwave backhaul gets a boost with multibandEricsson
With the exception of Northeast Asia, 65 percent of all cell sites will be connected to the rest of the network using microwave backhaul technology by 2020. Between now and then, the performance of microwave backhaul will continue to improve, supporting growing capacity needs through technology evolution and more efficient use of spectrum. So as the dominant backhaul media in modern networks, the ability of microwave to carry traffic plays a significant role in providing good mobile network performance.
Technology evolution, increased mobility, and massive digitalization continue to place ever more demanding performance requirements on networks. The constant pressure to increase performance translates into a need for more spectrum, and more efficient use of it – not just when it comes to radio access, but for microwave backhaul as well.
But spectrum is a finite natural resource, so technology developments not only need to be able to make use of higher frequencies, they also need to unleash the potential of all the untapped spectrum that exists.
Radio-link bonding is a well-established method for enhancing peak capacity, enabling multiple radio carriers to be aggregated into a single virtual one. So far, developments have focused on bonding carriers within the same frequency band. The multiband booster concept, however, uses radio-link bonding to aggregate carriers in different frequency bands, enabling the full spectrum potential to be unleashed.

5G (the fifth generation mobile communications) is scheduled to launch in around early 2020s. Even if it is not determined yet regarding the standard technology details, many researchers expect that 5G will transfer 1000 times more data, and thus, can connect billions of IoT (Internet of Things) devices at the same time.

Lifting Scheme Cores for Wavelet TransformDavid Bařina
The thesis focuses on efficient computation of the two-dimensional discrete wavelet transform. The state-of-the-art methods are extended in several ways to perform the transform in a single loop, possibly in multi-scale fashion, using a compact streaming core. This core can further be appropriately reorganized to target the minimization of certain platform resources. The approach presented here nicely fits into common SIMD extensions, exploits the cache hierarchy of modern general-purpose processors, and is suitable for parallel evaluation. Finally, the approach presented is incorporated into the JPEG 2000 compression chain, in which it has proved to be fundamentally faster than widely used implementations.

Unique visibility. Improved results.
Power quality is increasingly important to both power utilities and
industry regulators. This increased awareness is attributed to the
ongoing deregulation process, the aging electricity transmission
systems and increased environmental awareness. Consequently,
power utilities invest hundreds of millions of dollars in the
maintenance of their T&D infrastructures. Metrycom offers a
proven solution to utility companies who seek new technologies to
reduce costs, improve power quality, and enable enhanced grid
control.
Contamination of power line insulator strings is a major source of
power quality impairment, which often causes flashovers resulting
in shortcuts and wide-area power sags. The industry as a whole is
significantly impacted by quality impairment, causing enormous
yearly losses.
MS4000 monitoring and
transmission unit
The MS4000 is a wireless sensor solution for monitoring the
efficiency of T&D power lines. MS4000 employs unique partial
discharge sensors to detect contamination over power line insulator
stings. The system provides real-time information to maintenance
teams, helping them reduce operational costs and improve the
quality of the grid. Its wireless sensor units feature extremely low
power utilization, and can employ either power harvesting or a
primary battery (up to 20 years lifespan). Its highly reliable wireless
communications capabilities are based on frequency hopping and
IPv6 routing technologies.
Features
Unique Sensors: A single sensor covers 2km of power line.
Extremely Low power consumption
State-of-the-art IP wireless communication standards: supports
6LoWPAN (IPv6 over wireless – “the internet of things”).
Reliable Connectivity: for environments suffering radio interference/fading.
Long Range: point-to-point wireless connection (LOS) up to 5km, with
network coverage of up to hundreds of kilometers.
Flexible frequencies: 240MHz to 920MHz
IP Network IPv6 Communications over mesh radio network:
automatically create a wireless IP mesh radio network.
Supports large-scale mesh networks
Scalable and easy to deploy
Designed to operate in harsh conditions: temperature range of -40ºC to
85ºC, water and weather proof (IP67), resistant to electromagnetic
interferences and surges.
MS4000 sensor
Benefits
¤ Provides online grid visibility.
¤ Introduces real time high-voltage grid visibility of partial
discharges along the lines and in base sub-stations.
¤ Predicts flashovers
¤ Reduces interruptions and outages.
¤ Reduces maintenance costs by washing insulators at
the required segments of the power line and at the
optimal time.
¤ Provides feedback on the quality of insulator washing
operations.
¤ Provides infrastructure for additional sensor solutions
by including generic interfaces to many sensors types.
Metrycom enables a transition from
periodic to predictive maintenance
Currently, power utilities are spending hundreds of millions of
dollars every year in order to wash insulator strings, generally with
helicopters and trucks. The limitation that these methods impose
on maintenance crews is that they cannot get an overall view of the
contamination level in the power transmission and distribution
system. They are working blind and selecting the sections that
need to be washed mainly based on experience, not on fact. This is
proving extremely costly to the industry as a whole.
