Delays in Protection Devices and Their Effects on Selectivity: The Reaction Time Gap

IEEE Open Journal of Power Electronics
This Paper investigates how the internal delays of circuit breakers until the limitation of the fault current affect the selectivity of a low-voltage direct current (LVDC)-grid under short-circuit conditions.

Two basic ways to realise DC circuit breakers

The Journal of Engineering, 2019
As a key element of the DC grid, the technology of DC circuit breakers (DCCBs) still have difficulty to be widely used due to its large cost and volume. This paper studies the basic principle and its realisation methods for DCCBs.

Development and distribution of surface charge on epoxy resin under dc electric field in different gases

AIP Advances, 2018
Under DC voltage, charge accumulates on the break insulation of mechanical DC circuit breakers, distorting the local electric field, which increases the risk of break insulation failure.

Series LC DC circuit breaker

High Voltage, 2019
The article proposes a mechanical DC circuit breaker (CB) based on a series LC circuit. It requires two switches (a fast disconnector and an AC circuit breaker), an inductor and a capacitor, and therefore the cost is expected to be low. A series LC circuit is analysed and it is concluded that fault current will always have natural zero‐current ...
