Product Description
The combined line differential and distance protection SIPROTEC 7SL87 is part of the new SIPROTEC 5 series of modular, flexible and intelligent digital field devices.
With its modularity and flexibility and its high-performance DIGSI 5 engineering tool, the SIPROTEC 7SL87 fits perfectly for protection, control, monitoring, and measuring applications in electrical energy systems.
Main function:Differential and Distance Protection
Tripping:
- 1- and 3-pole, min. tripping time 9 ms
Inputs and outputs:
- 12 predefined standard variants with 4/4 or 8/8 current/voltage transformers, 5 to 31 binary inputs, 8 to 46 binary outputs
Hardware flexibility:Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system.
Width of housing:1/3 x 19'' to 2/1 x 19''
All functions can be configured freely with DIGSI 5. For the application of some of the functions, you require the appropriate number of free function points within the device. The function point calculator in the online configurator provides support in determining the required number of function points for your device.
