RET615是一种专用的变压器保护和控制IED(智能电子设备)，用于电力变压器，单元和升压变压器，包括公用事业和工业配电系统中的发电机变压器块。RET615是ABB Relion®产品家族的成员，也是ABB 615保护和控制产品系列的一部分。615系列简易爆炸装置的特点是紧凑和可抽出设计。
615系列重新设计，旨在充分发挥IEC 61850标准的潜力，实现变电站自动化设备之间的通信和互操作性。一旦为标准配置IED提供了特定于应用程序的设置，它就可以直接投入使用。
615系列ied支持一系列通信协议，包括IEC 61850与GOOSE消息传递，IEC 60870-5-103, Modbus®和DNP3。

IED的特点是，三相、多坡变压器差动保护具有瞬时级和稳定(偏置)级，为相对相、绕组间匝和套管闪过故障提供快速和选择性保护。除二次谐波约束外，先进的基于波形的阻塞算法保证了变压器通电时的稳定性，五次谐波约束函数保证了变压器适度过励磁时良好的保护稳定性。灵敏受限接地故障保护(REF)完成了整体差动保护，以检测靠近变压器中性点接地点的单相接地故障。对于绕组的保护，可以选择传统的高阻抗方案，也可以选择数值低阻抗方案。当使用低阻抗refr保护时，既不需要稳定电阻也不需要压敏电阻，并且作为进一步的好处，中性点接地ct的转换比可以与相电流互感器的转换比不同。由于它的单元保护特性和绝对选择性，不需要与其他保护方案进行时间分级，因此可以实现高速故障清除。
IED还集成了热过载保护功能，可监督变压器绕组的热应力，以防止绕组绝缘加速老化。两个绕组分别具有多级短路、相过流、负相序和接地故障后备保护。基于测量或计算的剩余过电压的接地故障保护也可用。最后，IED还提供断路器故障保护。
通过可选的硬件和软件，简易爆炸装置还具有三个光检测通道，用于断路器、母线和金属封闭室内开关柜的电缆室的电弧故障保护。
可选通信模块提供电弧故障保护传感器接口。快速脱扣提高了人身安全，并限制了电弧故障情况下开关柜内的物质损坏。

RET615J

RET615 is a dedicated transformer protection and control IED (intelligent electronic device) for power transformers, unit and step-up transformers including power generatortransformer blocks in utility and industry power distribution systems. RET615 is a member of ABB’s Relion® product family and part of its 615 protection and control product series. The 615 series IEDs are characterized by their compactness and withdrawable design.
Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability between substation automation devices. Once the standard configuration IED has been given the application-specific settings, it can directly be put into service.
The 615 series IEDs support a range of communication protocols including IEC 61850 with GOOSE messaging, IEC 60870-5-103, Modbus® and DNP3.

The IED features, three-phase, multi-slope transformer differential protection with an instantaneous stage and a stabilized (biased) stage to provide fast and selective protection for phase-to-phase, winding interturn and bushing flash-over faults. Besides second harmonic restraint an advanced waveformbased blocking algorithm ensures stability at transformer energization and a fifth harmonic restraint function ensures good protection stability at moderate overexcitation of power transformers. Sensitive restricted earth-fault protection (REF) completes the overall differential protection to detect even single phase-to-earth faults close to the neutral earthing point of the transformer. Either the conventional high-impedance scheme or a numerical low-impedance scheme can be selected for protection of the windings. When the low-impedance REF protection is used neither stabilizing resistors nor varistors are needed and as a further benefit the transforming ratio of the neutral earthing CTs can differ from those of the phase current transformers. Due to its unit protection character and absolute selectivity REF does not need time grading with other protection schemes, and therefore high-speed fault clearance can be achieved.
The IED also incorporates a thermal overload protection function, which supervises the thermal stress of the transformer windings to prevent an accelerated aging of the winding’s insulation. Multiple stages of short-circuit, phase-overcurrent, negative-phase-sequence and earth-fault back-up protection are separately available for both windings. Earthfault protection based on the measured or calculated residual overvoltage is also available. Finally, the IED also offers circuitbreaker failure protection.
Enhanced with optional hardware and software, the IED also features three light detection channels for arc fault protection of the circuit breaker, busbar and cable compartment of metal-enclosed indoor switchgear.
The arc-fault protection sensor interface is available on the optional communication module. Fast tripping increases personal safety and limits material damage within the switchgear in an arc fault situation.
