    There is built-in protection for surge voltages. However, cables for communication that may be subjected to overvoltage must have a primary protection, for example Protrol OVP. As a rule of thumb, one can say that cables that leave the building / station must be supplemented with a primary protection.

    IPC402x supports the communication protocols IEC 60870-5-101 and IEC 60870-5-104. In addition, there is an option which makes it possible to use IPC4020 as a local -101 Master. With this option it is possible to connect several -101 slaves to IPC4020 and access them in the remote control center.

    IEC 60870-5-101/-104 8.5.2 Earth Fault, General The IPC402x devices have two types of earth fault detectors; Protrol's patented method, and a complementary non-directional earth fault function that can be employed when switching onto faults. The non-directional function can also be used to detect fault connection, that a phase is missing or that one phase is connected with the wrong polarity.
