Tollgrade LightHouse(R) Smart Grid Sensor Software Drives Industry One Step Closer to Predictive Grid(SM) Analytics

(Marketwire Via Acquire Media NewsEdge) RESTON, VA -- (Marketwired) -- 06/26/13 -- Tollgrade Communications, Inc., the market leading provider of predictive fault analytics that is redefining a new standard for reliability at the world's largest electric utilities and broadband providers, announced today an industry first in the availability of the latest version of their LightHouse Sensor Management System (SMS) software with predictive grid analytics. The software works with their inductively powered medium voltage smart grid sensors that provide visibility throughout the distribution network. By providing four layers of analytical processing, the software accurately detects and classifies faults that cause outages in real-time for example, permanent faults on main feeders and blown fuses on laterals. This enables utilities to pinpoint the outage location and perform restoration faster because they know more about the fault and what equipment is required to repair it. For example, in two very large deployments in North America, the solution is detecting blown fuses on laterals 20 - 30 minutes before customers call to report the outage. All events are linked to map-view displays that make it easy for utilities to pinpoint the locations of problems for quick response and resolution.

"We need a paradigm shift in the way we think about the grid to successfully improve reliability. With Tollgrade LightHouse sensors, we can affordably inject intelligence where we need it the most -- the distribution grid where most faults that cause outages occur," said Edward H. Kennedy, President and CEO, Tollgrade Communications, Inc. "By having a library of fault events, outage detection and load planning data all in one software package, utilities can have the intelligence they need to restore outages faster today, and one day predict future problems before they cause outages on the distribution network." "Our increasingly digital economy is driving higher and higher reliability requirements for the electric grid. It's imperative that we make the necessary grid modernization upgrades required to ensure a safe and reliable supply of energy," said Becky Harrison, CEO Gridwise Alliance. "Improving situational awareness and grid intelligence are essential components of these grid modernization upgrades and are required to strengthen this nation's electric grid for the demands of the 21st century." Unlike other offerings Tollgrade's Lighthouse inductively powered Medium Voltage Sensors can increase the situational awareness throughout the distribution network and are offered as a single, affordable integrated solution including analytics, communications and a bundled five year data plan is included with one of their cellular sensor models.

Tollgrade Predictive Grid(SM)AnalyticsTollgrade's LightHouse smart grid sensors are deployed on the medium voltage grid at the substation and throughout the circuit to monitor real-time grid conditions and measure fault current. When fault current is detected, waveforms of the event are captured along with some background information (e.g. temperature, GPS location, time) which is communicated over a wireless or cellular network back to the LightHouse SMS software. The software conducts four layers of analysis on the information to build a strong foundation for grid intelligence: Layer 1: Event Capture Layer 2: Event Classification Layer 3: Trending, Planning and Reporting Layer 4: Predictive Grid Analytics The LightHouse SMS software classifies faults and disturbances that do not cause immediate outages in an effort to build intelligence about what might cause a power failure in the future. For example, incidents like momentaries or line disturbances are categorized and can be filtered to show trends across a circuit or during certain times of the year. A recent study by EPRI found that US power quality events cost US companies $24 billion a year. By using the analyzed data in the LightHouse system, utilities can mine this intelligence to learn how they might be able to prevent future outages. Once new cases are determined, the software is easily configurable to set-up alerts when these new conditions arise.

Tollgrade is the only solution that takes their smart grid sensor data through four layers of analysis to build a foundation for predictive grid analytics. This is required to improve overall accuracy and effectiveness. For example, in head-to-head field trials, older generation Fault Current Indicators (FCIs) generated as many as four false alarms to every true outage event confirmed by Tollgrade. This is important because utilities want to integrate the data from smart grid sensors and FCIs with other back-end systems such as Data Historians, Outage Management Systems, and Distribution Management Systems. Tollgrade offers the advantage that as the LightHouse SMS software "hands-off" this data, it can be trusted.

AvailabilityThis version of Tollgrade's LightHouse SMS software is available for purchase at the end of July, 2013. Interested utilities can contact getLightHouse@tollgrade.com for more information.

Delivering First Class Communications With WebRTC

This webcast captures a recent discussion about WebRTC between Jim Donovan, Director of Product Management at Oracle and Larry Hettick, Editorial Director and Senior Research Fellow at Webtorials. The topics cover WebRTC reliability, interoperability, and security--looking at how Oracle addresses these issues.

Oracle in Enterprise Communications

Most in the industry have heard of the acquisition of Acme Packet by Oracle. What you may not know is that Oracle has a number of telecommunications products including a UC suite, WebRTC Session Controller, and Operations monitoring tools. Oracle is pursuing both the enterprise and service provider.

ConnectCare & Unified Contact Manager

SPAN's ConnectCare is a WebRTC-based telemedicine app, which allows consumers to easily and instantly avail clinical healthcare from the providers, regardless of their location. This app is extremely useful to healthcare providers, patients and their caregivers alike.

WebRTC Security Concerns

This whitepaper covers two of the most relevant topics in communications industry today: WebRTC and security. We will introduce the problem of security in WebRTC including those traditional VoIP attacks that are going to be present in WebRTC services. Later we will mention ad-hoc WebRTC attacks and protection mechanisms, to close with an overview of identity management solutions.

Migrating Real Time Communications Services to the Web

In the Internet age, businesses that own fixed and mobile communication networks, including traditional Communications Service Providers (CSPs) of all kinds, are being challenged with some tough questions: How do we stay relevant to our customers?

Robust Enterprise Grade WebRTC Systems and Services


The emerging WebRTC standard has become one of the industry's hottest topics – and with good reason. Being able to "communications enable the web" has Communications Service Providers as well as Enterprises busily making plans for deployment. But, as these plans unfold, reality is starting to intrude on those plans. Our expectations of telephony services are much higher than web browsing. We expect the phone to connect instantly, operate with minimal disruption, and work seamless across any network, anywhere, at any time. There is also an understanding that phone service is inherently secure. With WebRTC, the expectation is for these applications to behave in the same manner.

This session looks at the user experience and expectations of a WebRTC Enterprise service. It will also cover how a WebRTC enterprise handles security, reliability, and interoperability within browsers and networks.
