數(shù)字式電容器保護繼電器SPAJ160C是一個集成的電流測量型多功能繼電器，設計用于電容器組的保護。電容器組用于電力系統(tǒng)中的無功補償和濾波。

電容器組通常用于防止由于諧波電流造成的過載和電容器組內(nèi)部故障引起的過壓。 同樣還可以防止一個已充電的電容器重新連接至一個有源網(wǎng)絡。所有這些功能都集成在電容器繼電器中。

一個完整的電容器組保護系統(tǒng)還包括過流、短路和接地故障保護。電容器保護繼電器SPAJ160C可以方便地通過SPACOM 系列產(chǎn)品的補充實現(xiàn)多種過流和接地保護功能。 

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
