System With Intelligent for Substation asset monitoring

The applications for industrial monitoring solutions is on the increase as video technology and the need for more data grows. Customers understand that more data allows them to make informed decisions and to take pro-active measures to increase operational reliability and prevent losses. A standards based approach means our video system connects and inter operates on any IP network.

Product Description



Representation of an electric power system traditionally consists of a one line diagram that shows essential information such as current and voltage levels, switch status etc. in a two-dimensional map. The information is real time and shown on the Human Machine Interface, (HMI), of the utility SCADA system. Integrating a video system with the SCADA HMI adds another dimension of real time visualization that is critical in making operational decisions and providing trending analysis input to prevent outages and prolong the life of high value assets.

While a SCADA or OMS/DMS system can provide critical information on the status of the system such as a breaker trip and power outage, visual and thermal video information can provide confirmation of the cause of the event and create real time situational awareness. Why did the breaker trip and what is happening now? Is a power line down? Is there a fire or leakage? With this information, the utility can safely and securely reduce the outage time by having visualization of the problem before rolling the truck.

More importantly, video information can reveal system inefficiencies by finding temperature hotspots in the system so the utility can make repairs before the failure occurs. Transformer losses, voltage drops and load imbalances can be caused by leakage current in insulators or high resistance connections in power system components. These components will often show increased heat buildup that can be detected by monitoring with thermal cameras. Continuous monitoring will provide alerts and trending data as the system goes through load cycles allowing the utility to perform condition based maintenance on the system before failures and outages occur.

Thermal Monitoring  

Continuous thermal monitoring systems anticipate, detect and respond rapidly to problems, thereby reducing maintenance costs, failures, outages and lost productivity. Detection of temperature increases in equipment using thermal cameras allows maintenance to be performed before a failure and unplanned shutdown occurs.

Intelligent video systems that utilize thermal cameras enable automatic detection of temperature increases in critical components and equipment. Thermal signatures are analyzed and used to predict potential equipment failures. The video system incorporates sophisticated thermal analytic algorithms to detect anomalies. Thermal rules are implemented to trigger automated alarm and email notification to alert operators of possible issues.

Asset monitoring with thermal imaging cameras is used to monitor operating temperatures of equipment as part of condition based maintenance program. Ensuring that equipment temperatures remain within limits leads to more reliable service and reduced downtime. Detection of hotspots is an indication of problems in the system that can lead to premature aging and failure. Maintenance can be performed when required as opposed to being based on a time-based schedule.

A single thermal camera on a mobile pan/tilt base can monitor multiple assets and areas such as connection points, transformers, bushings, insulators, isolators, arrestors, breakers etc. The camera can be programmed to cycle through a series of pre-set points and run analytics at each position.

Thermal analytics determine:

  • Absolute temperature
  • Temperature differential
  • Temperature rate of change

Visual Asset Monitoring

Visual Monitoring is used to assess the physical condition of remote sites and the assets inside them. Visualization can positively confirm:

  • Positioning and action of isolator arms
  • Reading gauges
  • Detection of arc flash
  • Detection of isolator arm movement
  • Detection of intruders and wildlife

Video Automation

When the video analytics detect events, whether they are thermal or visual, the system can be programmed to take further action. The automation system sends alerts through email or directly to the SCADA system where other actions can be triggered automatically or by an operator. The points that temperature monitoring system measures can map directly to analog points directly in the SCADA system. The digital inputs and outputs on the Digital Video Server can be connected to communicate with other monitoring or alarming systems.


Utilities invest heavily in underground systems in urban areas to keep the streets safer and free of the clutter of overhead wires. While underground systems have many benefits, they are also more expensive and take longer to install and repair than overhead systems and they tend to fail more often. The most common failures are due to transformers, faulty joints, splices and insulation breakdown that can occur due to moisture. An early indicator of an impending failure is the heat signature given off as resistance builds up in joints and splices. Failing insulation as the result of partial discharge also produces heat as current flows through the insulation to ground or phase to phase.

Failures in underground systems can be difficult and expensive to repair. Continuous thermal monitoring in vaults can detect the hot spots along the underground system and provide the utility with an early warning of impending failure. Utilities can take measures such as rerouting power to relieve the strain and avoid an outage until preventive maintenance can be performed.




Video monitoring is a key component of a comprehensive physical security plan as mandated in NERC CIP 014 and as described in the NERC Security Guideline for the Electricity Sector. Video monitoring plays an important role in preventing and investigating various types of security threats including theft, unauthorized access, vandalism and sabotage to the critical infrastructure. Unmanned remotes sites provide an easy target for intruders. Security threats at remote facilities are constant with the theft of copper and other high value components and material. Copper theft is not only an asset loss but is also a danger to the intruder and utility personnel as the copper is often taken from live systems.

Intelligent video monitoring systems can automatically detect intrusions and send notifications so that operators can alert authorities and dispatch of security personnel. The monitoring system can also record and archive events to provide authorities with video evidence of the crime.

Video monitoring is an important tool to meet regulatory compliance for physical security of critical infrastructure. A video system with built in intelligence and analytics can meet the most important criteria that is outlined in the NERC CIP Critical Infrastructure Guidelines for Physical Security including the ability to: detect and deter intruders, assess situations and communicate with remote alert messages, respond with triggered lights and alarms, intelligently analyze the video inputs and provide the ability to audit with archived records.

The onboard analytics engine processes the digital video inputs and automatically detects:

  • Motion
  • Boundary Crossing
  • Camera Tampering
  • Loitering

Video can be linked with other physical security systems such as access control to provide positive visual identification of personnel or vehicles entering the site through controlled gates and doors. A video system integrated with other physical security systems provides a comprehensive security strategy.
