Concept
Insulation breakdown occurs when an insulating material fails to prevent the flow of electrical current, often leading to short circuits or equipment damage. This phenomenon can be caused by factors such as excessive voltage, aging of materials, or environmental conditions like moisture and temperature fluctuations.
Concept
Dielectric failure occurs when an insulating material loses its ability to withstand an electric field, leading to a breakdown and allowing current to pass through. This phenomenon can result from excessive voltage, material defects, environmental conditions, or prolonged stress, and can cause significant damage to electrical systems.
Concept
Transient voltage refers to temporary, short-duration spikes or surges in electrical voltage that can occur due to events like lightning strikes, switching operations, or faults in the power system. These voltage spikes can cause significant damage to electrical equipment and systems if not properly managed or mitigated.
Concept
Electrical stress refers to the force exerted on electrical insulation or components due to high voltage, which can lead to failure or breakdown if the stress exceeds the material's dielectric strength. Managing Electrical stress is crucial in designing safe and reliable electrical systems to prevent damage and ensure longevity.
Concept
Overvoltage is a condition where the voltage in an electrical circuit exceeds the normal operating level, potentially causing damage to equipment and posing safety hazards. It can result from external factors like lightning or internal issues such as equipment malfunction or improper system design.
Concept
Arcing refers to the discharge of electricity through the air between conductors, which can cause damage to electrical systems and pose safety hazards. It is characterized by a visible arc and can result from equipment failure, insulation breakdown, or improper installation.
Concept
Rated voltage is the specific electric potential difference that an electrical device or equipment is designed to operate at optimally. Exceeding this voltage can reduce the lifespan of the device or lead to dangerous operational scenarios.
Concept
An over-voltage relay is a protective device designed to monitor the voltage level in electrical systems and activate a circuit breaker if the voltage exceeds a pre-set level, preventing damage to equipment and ensuring safety. It is widely used in power systems to maintain voltage stability and protect electrical components from potential over-voltage harms, such as insulation breakdown or equipment failure.
