When a surge arises in case of lighting strike or a switching impulse, which could be the cause for insulation deterioration and at the end dielectric breakdown. This is a severe process, that depends on several factors, such as the frequency at which the transformer is exposed, the configuration of the system, the application of the component etc.
Motors and distribution transformers are constantly exposed to fast surges, when they are switched by circuit breakers. Reigniting occurs during the switching of motors and transformers with vacuum circuit breakers, because of their ability to interrupt high-frequency currents.
This article presents the analysis of the measured and calculated voltages along the high-voltage winding of the transformer.
Every photovoltaic system (PV system) has its own constraints, each one different from the other. Some are related to shades, others to space or costs.
Radical energies and complex mechanisms are used and implemented in all industrial processes nowadays. Such processes can potentially cause serious harm to personnel or property during an accident. In such a scenario, absolute safety is not achievable, reduction of risks to acceptable level is possible.
