In order to deal with the increasingly harmonic problems caused by nonlinear loads and the consequent distribution transformer noise problems in low-voltage distribution systems, a harmonic-filtering distribution transformer applied in the 10/0.38kV box-type substations is designed and fabricated. As a result, the passive harmonic filters are contained and installed in the substations to work together...
The electronic circuit breaker used in DC microgrids are required to work within their safe operating areas bounded by temperature, voltage and current limits. Traditional approach managed to protect these switches through rapid current cut-off operations at over-load or fault situations, but failing to avoid the disturbance induced by transient current surges or noises which are not harmful to the...
