Professional VLF Equipment: The Key Technology for High-Voltage Testing | Creativeit Group
Looking for reliable, state-of-the-art equipment for testing medium- and high-voltage cables? At Creativeit Group we offer the most advanced professional VLF (Very Low Frequency) equipment on the market, ideal for critical electrical applications.
What is VLF technology?
VLF (Very Low Frequency) is a technology used in insulation test equipment that operates at frequencies between 0.1 Hz and 0.01 Hz, much lower than the power frequency (50/60 Hz). This makes it possible to apply high voltages to electrical equipment such as cables, transformers, and generators without causing thermal damage or insulation degradation.
How does it work?
VLF equipment generates a sinusoidal or pulse wave at a very low frequency, simulating the service conditions of an electrical system. This voltage is applied to the component under test, making it possible to detect insulation weaknesses and incipient faults and to confirm its ability to withstand voltage.
Why use VLF equipment?
Using VLF technology is essential to ensure the reliability and safety of electrical installations. Here are some key reasons:
- Preventive fault detection: avoids outages and catastrophic failures
- Lower thermal stress on the insulation compared with conventional AC tests
- Regulatory compliance: alignment with international standards such as IEEE 400.2 and IEC 60502
- Lower maintenance and replacement costs from unexpected failures
- Ideal for field testing, thanks to its compact and portable design
- Greater network reliability by ensuring the integrity of the electrical system
Main applications
✅ Acceptance testing of new medium- and high-voltage cables
