The SPRECON-EDIR is used as an extended and directional earth fault and short circuit indicator using and evaluating different procedures for permanent monitoring in compensated, isolated or rigidly earthed medium-voltage networks.

The individual earth fault location procedures, which are carried out simultaneously, can be prioritised and combined into a single message.

The EDIR function is available in the following forms:

- SPRECON-EDIR as a stand-alone unit in a control panel housing according to IEC 61554 (W x H x D = 96 x 48 x 90 mm).
As a software module in the device series

- SPRECON-E-P DS6 (combined overcurrent protection and control devices)
SPRECON-E-P DD6 (combined distance protection and control devices)

The software is identical for all series, based on SPRECON-EDIR. In the SPRECON-E-P combined units, the EDIR function runs with reduced priority compared to the system protection function of the units.

The multifunctional SPRECON-E-P units are characterised by a consistent separation of the following functions:

- Control technology
- Protection technology
- Earth fault indication
