Replacing MB85RS128, ferroelectric memory GX85RS128 is applied in power arc flash protection devices

Arc flash protection devices primarily achieve their protective functions by detecting arc flashes and overcurrent in circuits. When arc flashes and overcurrent occur in a circuit, the protection device immediately issues a trip signal to disconnect the fault point, thereby ensuring the safe operation of the power system. Therefore, arc flash protection devices play a crucial role in power systems. They can promptly detect arc flashes and overcurrent in circuits and swiftly disconnect fault points to safeguard the safe operation of the power system.

Arc flash protection devices require rapid and accurate recording and storage of critical power parameters and event information to enable timely detection and response to potential hazardous arc flash faults. This article introduces the application of ferroelectric memory GX85RS128 in the storage module of such devices. The GX85RS128‘s fast write capability enables it to store relevant data from the instant an arc flash occurs within an extremely short timeframe, ensuring no critical information is overlooked.

The non-volatile nature of the ferroelectric memory GX85RS128 ensures that data stored in the memory remains intact even in the event of a sudden power system failure causing a power outage. This facilitates subsequent fault analysis, cause tracing, and system recovery. Key parameters:
