To meet the ever-increasing load growth, existing and future overhead line components, including connectors, operate at high temperatures. Confidence in the reliable performance of these components is critical because their failure can lead to a downed line and extensive disruption of power to customers. Operation at elevated temperatures can accelerate the aging process, making the issue of lifetime performance even more critical.
We perform a wide range of tests on high temperature conductors including qualification and performance tests for the thermal, mechanical, environmental, and electrical performance of:
- Transmission and Distribution Connectors
- Electric Power Connections for Substations
- Ground Grid Connectors
- High Temperature Connectors and Accessories
Why Us?
-
Health Assessments
One of our many connector health assessments, undertaken by our experienced subject matter experts, will inform your maintenance schedules, ensuring work is done when it is needed.
-
Validation of Design Criteria
By validating the design criteria and variables, we ensure connectors will last for the design life of the overhead lines and that production parameters and variables match the design criteria.
-
Independent Insights
Industry standards and manufacturer's specifications are used to conduct qualification and performance tests enabling us to provide independent, objective data and insights.
-
Field Commissioning of Connector Installations
We ensure that when connectors are installed in the field they comply with the QA/QC parameters of connectors tested in the lab during the qualification of the design (type test).
-
New Product Qualification
Our state-of-the-art lab can simulate excessive and/or unique stresses for new product development and qualification.
-
Help Prevent Future Problems
Expert forensic analysis can determine potential failure modes & bring to light root causes in order to avoid any unexpected failures.
Technical Abilities
Current Cycle Test (ANSI C119.4 and ANSI C119.7)
Cycling heating tests evaluate the electrical and thermal performance of connectors utilizing accelerated thermal aging.
Tests can be done under mechanical tension as well as those indicated in IEC 61284 or ANSI C119.7.
Heat Rise
We perform heating tests to evaluate the electrical performance of the substation connectors by evaluating the thermal profile of connectors.
Pullout/Tensile Strength
Maximum load and sustained load tests evaluate the mechanical capacity of your connectors when subjected to heavy ice and/or wind loading, or other steady or cyclic loads.
Torque Strength
Torque strength of the bolted connectors and hardware to evaluate relaxation during test or in service.
Corrosion Tests: Salt Fog, Acid Bath
Testing of corrosive environments on transmission and distribution systems and underground connectors.
Freeze-Thaw
Evaluate the effects of temperature changes on underground connectors.
Vibration
Test the performance of clamps and other hardware when subjected to aeolian vibration.
Condition Assessment of Aged Connectors
We can help identify the performance of existing connectors in the line to identify key parameters for inspection of faulty connectors and assist utilities in identifying potential problems to help them increase the reliability of the line.
Failure Analysis
Understand the causal factors and identify the root cause of the failure to take the necessary steps needed to increase the reliability of the line.
Fault Current
Evaluate the ability of new or aged connectors to withstand typical fault currents levels in the line. This is especially important for preformed, bolted, or automatic connectors.
Sheave Test
When using splices in stringing operations the effects of passing the splice through the stringing blocks can impact the mechanical integrity of the connector/conductor assembly. We offer sheave testing services to factor this added stress into understanding the integrity of your components and impacts of component installation. Testing guidelines and standards have been addressed in the CSA C57-2016 (Annex E) where the main parameters are the rollover angle, mechanical tension and the number of passes.
We have the capacity to customize the parameters to meet the needs of the utilities and manufacturers to ensure that when splices are used in the stringing operations, they will not compromise the quality and reliability of the line.
X-Ray and IR Imaging Evaluation
- Used in typical tests for condition assessment.
- Used to evaluate the installation of connectors.
