VLF Cable Testing
The Applied Technical Services Family of Companies (FoC) conducts VLF cable testing services that confirm a cable’s reliability.
What is Very Low Frequency Testing?
Very low frequency (VLF) tests verify the quality of a cable’s insulation. During the testing process, the technician applies low frequency AC to the table. The applied voltage is significantly higher than a normal operating voltage, which challenges the insulation and exposes any weaknesses. Ineffective insulation will break down during the test and result in a failure and effective insulation will withstand the voltage for the duration of the test. VLF tests are an effective choice for field tests because of their lighter weight and increased portability when compared to their higher frequency alternatives.
Our VLF Cable Testing Services
Our electrical testing personnel use our A2LA-accredited lab to conduct VLF cable tests that assist our clients in their early fault detection strategies. We recognize the importance of predictive maintenance, and our VLF cable tests are a highly effective way for our clients to receive service at their convenience as we offer both in-lab and on-site services.
Why is VLF Cable Testing Important?
Very low frequency cable tests are an effective way of identifying and resolving weaknesses in cable insulation, allowing manufacturers to adjust their designs to avoid failure. The testing process is highly efficient, and it offers insight into the following:
- Manufacturing defects and weaknesses
- Factors that cause insulation wear and tear, such as moisture, heat, and dirt
- Potential factors that may result in safety risks to people and property
Failure during a VLF cable test can be attributed to a variety of factors and conditions. Voltage that exceeds normal operating ranges can trigger a cable’s failure, which may create unsafe conditions for the end user, such as fire risk and electrical shocks.
Our Commitment to Quality
The Applied Technical Services Family of Companies (FoC) provides professional inspection, consulting engineering, and testing services to commercial and industrial businesses. Our nationwide network of experts works closely with our clients to ensure that our services meet their direct needs while also ensuring that we comply with the necessary standards. Over the years, we’ve acquired multiple internationally recognized standards, such as ISO 17025 and ISO 9001.
