n 1997 ABB introduced a new series of medium-voltage circuit-breakers with a magnetic drive instead of a spring-based operating mechanism [1]. This solution soon proved to be much more reliable than its predecessor. Following up on the success of the magnetic drive, ABB has now developed a new controlled switching technology which will allow the closing and opening operations to be synchronized with the power network. Synchronous switching, also called ‘point on the wave’ switching, is a…

Getting parameters in power systems based on adaptive linear neural network

TLDR
An approach is proposed using adaptive neural network to detect fault current at the time of vacuum interrupter synchronous breaking short-circuit, to estimate the extinguishing moment of arc for optimally breaking the contact and the effectiveness and speediness of the proposed method.

Improved LSTM Memory Recursive Neural Network Precise Compensation and Prediction for Phase Selective Switching Device

TLDR
It is concluded that the closer the circuit breaker's closing is to the zero crossing, the less influence it has on the AC system, and a compensation method based on the improved LSTM neural network is proposed to predict the closing delay of circuit breakers.
