Electric Power Transmission Networks

PrismaPower, Prisma’s next-generation smart solution for electric power transmission networks, uses patented Hyper-Scan Fiber-Sensing™ technology enabling ultra-sensitive and intelligent-learning detection to provide real-time intelligence and uniquely reliable monitoring capabilities.

The solution lowers deployment costs by using overhead OPGW pre-deployed cables. These cables, which are part of most modern infrastructures, operate as “sensors” and enable PrismaPower to monitor and detect power lines at remote locations, providing surveillance and real-time threat detection for up to 100 km per PrismaPower unit or 200 km per dual-unit.

PrismaPower’s technology provides alerts regarding required maintenance and potential threats to the network in real time – facilitating earlier detection and optimizing performance.

 

PrismaPower identifies the acoustic signature of each event at or near overhead transmission lines, at a resolution that allows classification of the events and identification of their locations – with unprecedented accuracy – as it drastically reduces the “noise” of false positive and negative alarms.

PrismaPower facilitates transmission line monitoring for maintenance – preventing accidental, criminal or malicious activity – and ensures maximum efficiency by flagging for classification a range of events that can include:

  • Extreme wind

  • Temperature changes and related weather conditions, such as fire and ice

  • Flashovers 

  • Predicted flashovers over contaminated insulators 

  • Network failures

  • Lightning strikes

  • Suspicious activities at the tower

  • Vandalism

  • Individual climbing a tower with or without a harness 

  • Tower instability

  • Drones above the lines

Solution Architecture

PrismaPower’s platform is Plug & Play – with zero infrastructure installation, and minimal maintenance. 

 

The platform provides monitoring for up to 100 km per PrismaPower unit or 200 km per dual-unit. The unit is connected to the Command & Control (C&C) unit in the customer’s operating center. 

The PrismaPower unit attaches directly to the customer’s fiber-optic cable with a simplex SC/APC connector, which connects to a single fiber in the patch panel – ensuring access to a single fiber only, i.e., not compromising the activity or security of any other fibers in the cable. An Internet connection (LAN or WiFi) is required to transmit the monitored data to a C&C unit. 

 

Scaling up involves use of multiple PrismaPower units, each of which provides coverage for up to 100 km. Each unit is located in a communication room. All of the units combined require a single C&C unit in the customer’s  operating center.

There is no need for discrete sensors. Upgrades are software based; no hardware upgrades are required.

Key Features & Benefits

Systems involving thousands of sensors along the network are expensive for deployment, operation, and maintenance. The alternative is fiber sensing – using very long fibers as sensors – which is probably the most cost-effective solution. But before PrismaPower, existing solutions were ineffective due to high false alarm rates, poor target classification, and limited ability to use pre-deployed optical communication cables as "sensors".  

PrismaPower solves all of all these issues thanks to its revolutionary Hyper-Scan technology, which offers 100x sensitivity improvement over alternative systems.

 

PrismaPower’s solution applies Big Data techniques to raw data of unparalleled quality. Data sets are several orders of magnitude wider, with significantly higher SNR (signal-to-noise ratio) levels – leading to very high detection probability and advanced target classification. 

 

Upgrades to the system are software based and can be installed remotely.

All Information Consolidated in a Single Location & Single Display

The C&C unit presents the consolidated data of multiple units, with a real-time map and detection table that displays the following information:

  • Detection of events

  • Classification of events

  • Location of events at a high resolution 

  • Identification of multiple, simultaneous events without interference or crosstalk
