Infrared Viewing Windows
Overheating is frequently an early indication of electrical equipment damage or breakdown. Infrared scanning can detect invisible hot spots in electrical systems, which can decrease the potential for unexpected downtime. Typically, dead-front electrical panels must be removed to allow a clear view of connections to ensure the integrity of the results. Our infrared windows and panel covers reduce the need to remove panels or covers for infrared and visual inspections since they are permanently retrofit into the electrical equipment. Once installed, infrared inspections can be performed safely and without downtime.
Wireless Temperature Monitoring System
Provides continuous online temperature monitoring of critical connection points in electrical equipment. Wireless sensors are installed into low- and medium-voltage equipment during a planned outage. Once in place, sensors transmit temperature data that provides operations and maintenance personnel with a means to:
Partial Discharge Monitoring
- Evaluate the present condition of the equipment and determine its operational status
- Detect abnormal conditions, such as heat rise, at an early stage and initiate corrective actions
A leading indicator of insulation breakdown, partial discharge occurs in electrical equipment under high voltage stress, usually 2,000 V or greater (higher voltages yield more potential for damage or downtime). Partial Discharge Monitoring Technology detects impending insulation breakdown and provides early warning alarms. Sensors are installed during a planned outage and wired to a monitoring unit, which can be tied into an existing SCADA system via open protocol. Web hosting is also available. Partial Discharge technology is applicable on equipment rated 5 kV to 500 kV where the age of the insulation would be cause for concern.
Insulating Fluid Analysis
An oil analysis detects the breakdown of the oil paper insulating system in transformers and other potential issues. Optimum intervals for oil processing, repairs or replacement can then be determined.
Transformer Temperature Monitoring
The Model 98A digital temperature controller from Schneider Electric continuously monitors up to three Type K thermocouples in the windings of a dry type transformer and includes automatic fan activation, alarming and high temperature trip. Temperature monitoring helps to improve transformer life expectancy by reducing overload heat damage which could lead to costly downtime.
Intelligent Protective Device
Upgrading circuit breakers and motor control centers with smart technology provides the current state of the equipment to better plan maintenance activities. Solutions include:
- Electronic trip units or circuit monitors for circuit breakers
- Intelligent motor starters for motor control centers
Circuit Monitor Analysis Circuit monitors record data relating to voltage, current, and power. Our power system engineers will analyze the data to help determine where and when destructive transients, sags and swells can occur. Their report will also include corrective recommendations.
