3 PRODUCT SCOPE
The P14x range of feeder management IEDs has been designed for all applications where overcurrent and earth
fault protection is r
equired, from distribution to transmission voltage levels. All devices within the range are
suitable for solidly-earthed, impedance-earthed, Petersen coil-earthed and isolated systems.
All devices provide an extensive range of protection functions as well as a comprehensive range of additional
features to aid with power system diagnosis and fault analysis.
The P14x range consists of five models; the P141, P142, P143, P144 and P145.
● The P141 is the most basic model providing a cost-effective solution for most applications
● The P142 provides all the functionality of the P141, as well as four-shot three-pole autoreclose functionality.
● The P143 provides all the functionality of the P142, as well as a fourth VT for Check Synchronisation
functionality. Due to its choice of larger case sizes, the P143 can also provide significantly more I/O (opto-
inputs and relay outputs). Model P also provides switch status and control for disconnectors, load break
switches and earthing switches.
● The P145 provides all the functionality of the P143, but in addition has 10 function keys for integral scheme
or operator control functionality such as circuit breaker control, autoreclose control and remote
communications control. This makes it especially suitable where a complete scheme solution is required.
● The P144 has been designed such that it needs just two two Current Transformer inputs for two phases. The
third phase is derived mathematically inside the IED. It also has a fourth VT input to be used for a measured
neutral voltage (instead of check sync functionality) which makes it suitable for isolated and compensated
systems.

3.1 ORDERING OPTIONS
All current models and variants for this product are defined in an interactive spreadsheet called the CORTEC. This is

A copy of the CORTEC is also supplied as a static table in the Appendices of this document. However, it should only
be used for guidance as it provides a snapshot of the interactive data taken at the time of publication.
