数字式电容器保护继电器SPAJ160C是一个集成的电流测量型多功能继电器，设计用于电容器组的保护。电容器组用于电力系统中的无功补偿和滤波。

电容器组通常用于防止由于谐波电流造成的过载和电容器组内部故障引起的过压。 同样还可以防止一个已充电的电容器重新连接至一个有源网络。所有这些功能都集成在电容器继电器中。

一个完整的电容器组保护系统还包括过流、短路和接地故障保护。电容器保护继电器SPAJ160C可以方便地通过SPACOM 系列产品的补充实现多种过流和接地保护功能。 

REV615 is a dedicated capacitor bank protection and control relay for protection, control, measurement and supervision of capacitor banks used for compensation of reactive power in utility and industrial power distribution systems.

REV615 has been designed to be the main protection for H-bridge, double Y and single Y-connected capacitor banks and feeder cables. Additionally, REV615 can be used to protect harmonic filter circuits when no significant harmonic component is higher than the 11th. REV615 is available in two standard configurations, one of which has been preconfigured for H-bridge connected capacitor banks and has a three-phase unbalance protection, whereas the other has been preconfigured for double Y-connected capacitor banks and has a single-current unbalance protection.

REV615 fully supports the IEC 61850 standard for communication and interoperability of substation automation devices, including IEC 61850-9-2 LE, and can now also benefit from the extended interoperability provided by Edition 2. REV615 further supports both the parallel redundancy protocol (PRP) and the high-availability seamless redundancy (HSR) protocol, together with the DNP3, IEC 60870-5-103 and Modbus?protocols. With the protocol adapter SPA-ZC 302, Profibus DPV1 can also be used.   

REV615 is a member of ABB’s Relion? product family and part of its 615 prote
