Hibafeszültség

Hibafeszültség refers to a voltage that appears across an electrical insulation system due to a fault condition. This can occur in various scenarios, such as a short circuit, an insulation breakdown, or a ground fault. When a fault happens, the normal electrical path is disrupted, leading to the creation of unintended voltage differences across normally insulated components. These voltages can be transient or sustained, depending on the nature and duration of the fault.

The presence of hibafeszültség can pose significant safety risks, including electric shock to personnel and damage to equipment. It can also lead to arcing and fire hazards. Therefore, detecting and mitigating hibafeszültség is a critical aspect of electrical safety and system reliability. Various protective devices, such as fuses, circuit breakers, and residual current devices (RCDs), are designed to detect fault conditions, including the presence of hibafeszültség, and quickly disconnect the power supply to prevent further harm.

In power systems, hibafeszültség can also refer to the voltage measured between a conductor and the earth during a single-phase ground fault. This voltage can be significantly higher than the normal phase-to-neutral voltage, especially in ungrounded or high-impedance grounded systems. Monitoring and managing these fault voltages are essential for maintaining system stability and preventing cascading failures. The analysis of hibafeszültség is a key part of electrical fault diagnostics and troubleshooting.
