FAQ
Q: Where are high-voltage transformers used?
A: High-voltage transformers efficiently transmit electricity in power systems, decreasing voltage for long-distance distribution. Specifically designed for testing in high-voltage labs, they simulate breakdowns and insulation failures to ensure equipment reliability, withstanding surges, and transient voltages during testing.
Q: What are the problems with dry-type transformers?
A: Dry-type transformers are vulnerable to damage from lightning strikes. To address this, the iron core is grounded at multiple points for enhanced protection. Furthermore, a short circuit current 20~30 times higher than the rated current may be produced for grounding and interphase short circuits at the low-voltage side.
Q: Why is hipot testing needed?
A: The hipot test assesses insulation integrity by checking dielectric strength against the ground. It evaluates if the equipment can withstand over-voltage scenarios exceeding its peak operating voltage. This test ensures the device can handle electrical stress and prevent failures due to excessive voltage.
