stängningsspänning
Stängningsspänning, or closing voltage, refers to the voltage across a switch or circuit breaker at the moment it is closing. This voltage is generally lower than the system voltage due to the impedance of the conductors, any contact resistance in the closing contacts, and potential voltage drops across other components in the circuit. As the contacts close, the resistance decreases, and the voltage across the switch will approach the system voltage.
The magnitude of the stängningsspänning is influenced by several factors, including the design of the switchgear,
Understanding stängningsspänning is important for the design and operation of electrical systems. It can affect the
