I recall a project where we were tasked with testing an extensive network of high voltage cables across a large industrial site. The client was concerned about the potential energy costs associated with the testing process. By utilizing an AC Resonant Test System, we were able to conduct all necessary tests while keeping energy consumption—and therefore costs—significantly lower than what would have been incurred using other methods. The cost savings were substantial, and the client was able to allocate the saved resources to other critical areas of their operation.
Reduced Equipment Wear and Maintenance Costs
Minimizing Stress on Equipment
AC Resonant Testing is not only efficient in terms of energy use but also in how it minimizes stress on both the test system and the equipment under test. The controlled application of voltage through resonance reduces the wear and tear that typically occurs during high voltage testing. This means that both your testing equipment and the infrastructure being tested are subjected to less stress, leading to longer equipment life and fewer maintenance requirements.
Example: Long-Term Savings from Reduced Maintenance
In one particular instance, we noticed that our AC Resonant Test Systems required far less frequent maintenance compared to other systems we had used in the past. This reduction in maintenance needs translated into significant long-term savings, as the cost of servicing and replacing worn components was markedly reduced. Additionally, the equipment under test also benefited from the gentler testing process, showing fewer signs of wear and extending its operational lifespan.

Another cost-saving aspect of AC Resonant Test Systems is their versatility. These systems can be adapted to test a wide range of equipment, from medium voltage to extra-high voltage cables, transformers, and GIS components. This adaptability reduces the need for multiple specialized testing systems, allowing you to accomplish a variety of tests with a single setup.
Example: Savings from a Versatile Test System
I worked on a project where we needed to test a diverse array of equipment, ranging from medium voltage cables to large transformers. Initially, the project plan called for multiple testing systems to be deployed, each tailored to a specific type of equipment. However, by utilizing an AC Resonant Test System, we were able to handle all the testing requirements with one system, eliminating the need for additional equipment purchases or rentals. This approach resulted in considerable cost savings and streamlined the testing process.
Efficiency in Field Testing Reduces Labor Costs
Faster Setup and Testing Times
The efficiency of AC Resonant Test Systems extends beyond energy savings and reduced equipment wear. These systems are also quicker to set up and operate, which can significantly reduce labor costs, especially in field testing scenarios. The ability to quickly reach the required test conditions and complete tests in less time means that your team spends less time in the field, reducing both labor hours and associated costs.
Example: Reduced Labor Costs in a Field Testing Project
During a field testing project in a remote area, the efficiency of our AC Resonant Test System was a major advantage. The system’s quick setup and ease of use allowed us to complete the testing ahead of schedule, reducing the number of days the team needed to be on-site. The savings in labor costs were substantial, and the project was completed under budget, much to the satisfaction of the client.
Improved Test Accuracy Reduces the Need for Retesting
Getting It Right the First Time
Accuracy is paramount in high voltage testing, and AC Resonant Test Systems excel in this area. The precision with which these systems can apply the required test conditions leads to highly reliable results. This accuracy minimizes the likelihood of having to perform retests, which can be both time-consuming and costly.
Example: Cost Savings from Accurate Testing
On one project, a colleague and I were testing a series of newly installed high voltage cables. The initial tests using another method produced inconsistent results, leading to concerns about the cables’ integrity and the need for retesting. We then switched to an AC Resonant Test System, and the results were clear and consistent, eliminating the need for additional tests. This not only saved time but also avoided the extra costs associated with retesting, allowing the project to move forward smoothly.
