The SIPROTEC 7KE85 is a powerful fault recorder with the integrated measuring of synchrophasor (PMU) according to IEEE C37.118 and Power Quality measurement according to IEC 61000-4-30. Due to the high flexibility of trigger functions, the SIPROTEC 7KE85 is ideally suited to monitor the entire energy value chain from generation to distribution. The powerful automation and flexible configuration with DIGSI 5 complement the range of functions.
Main function: Fault Recorder
Inputs and outputs: 4 predefined standard variants with up to 40 current and 40 voltage transformers, 43 binary inputs, 33 binary outputs
Hardware flexibility: Flexibly adjusted and expandable I/O quantity structure within the scope of the SIPROTEC 5 modular system.
Housing width: 1/3 to 1/1 x 19‘‘
