ABB REF615C_E HCFDACADABC2BAN11E is ABB's microcomputer protection device. The following is some common information about the microcomputer protection device:

** Usage ** :

It is mainly used for the protection, control, measurement and monitoring of feeders and can be applied to public substations and industrial distribution systems, including radial, ring and grid distribution networks with or without distributed power sources.

** Features and Functions ** :

- ** Support a variety of grounding methods ** : suitable for different power networks and grounding methods, conventional transformer or sensor transformer can be selected.

- ** Extensive protection features ** :

- ** Overcurrent protection ** : includes directional/non-directional overcurrent protection.

- ** Ground protection ** : Directional and non-directional ground protection can be provided for the feeder, in addition to directional ground protection, the standard configuration also provides admittance ground protection, harmonic ground protection or power ground protection. In addition, there are sensitive ground protection, phase break protection, transient/intermittent ground protection, overvoltage and low voltage protection, zero sequence overvoltage protection, positive sequence low voltage protection and negative sequence overvoltage protection.

- ** Frequency protection ** : Devices with standard J and N configurations provide frequency protection, including overfrequency, low frequency and rate of frequency change protection.

- ** Optional automatic reclosing function ** : For overhead line feeders, standard N also provides multi-frequency admittance ground protection to provide selective directional ground protection for high-impedance grounded networks. Its dedicated filtering algorithm ensures that the fault direction can be identified safely and reliably in the case of intermittent grounding and arc reignition, and good reliability and sensitivity can be ensured in the case of low resistance grounding, high resistance grounding, or transient grounding/intermittent grounding/arc reignition.

- ** Optional arc protection ** : By configuring the corresponding hardware and software, three arc detection channels can be added to realize the arc protection of the cable room, the bus room and the circuit breaker room of the metal armored switchgear. When the arc fault occurs, the arc protection can act quickly in a short time to ensure personal safety and minimize the damage of the arc fault to the switchgear.

- ** Strong communication features ** : Support for a variety of communication protocols, such as IEC 61850 Version 2, IEC 61850-9-2 LE based process bus, IEC 60870-5-103, Modbus®, etc. Profibus DVP1 communication is also supported through the SPA-ZC 302 protocol converter.

- ** Preset Standard configuration ** : The device is preset in a standard configuration to speed up the installation of the device so that it can be put into service as soon as possible and make the configuration easy to change.

- ** Large graphical display ** : can display a customizable single line chart, convenient for operators to view system status and information.

Microcomputer protection device is a power system protection device based on microcomputer technology, which has many advantages compared with traditional relay protection devices, such as:

** High reliability ** : controlled by a computer program, the program has strong analytical ability, can identify external interference and take corresponding measures, and can accurately identify and power off operations in complex lines.

- ** Strong flexibility ** : Complete the protection function through the logical operation of the software, which can be reasonably protected according to the difference of the protected object or different protection principles, and the program can independently choose the relay protection combination.

- ** Rich features ** : In addition to basic protection functions, it may also have additional functions such as fault recording, harmonic analysis, and support for remote monitoring.
