IPC4020 for 4-6 bays
Fault Detector and Remote Terminal Unit
13/5 2022
The BIG news are now here...
...or at least the long news! The new IPC4020 with up to six individual fault detectors for larger secondary substations has arrived.
IPC4020 and IPC4020exp has already 16 binary inputs and 8 binary outputs - but in some cases more than that are needed. PDCIO is a compact and scalable I/O extension for your IPC when there are plenty of I/O in the secondary substation.
PDCIO is configured using the web settings of the IPC, both locally in the secondary substation and at the remote control location.

LoRaWAN interface
The new PxL is a communication interface for LoRaWAN 868 MHz. It has a serial interface to connect to the IPC402x series of fault detectors.
Please contact us if you need a cost-efficient data acquisition using LoRaWAN.
The Finnish technology company and family business Ensto has acquired a majority stake in Protrol AB. The transaction brings growth opportunities for both companies, their personnel, customers and partners. Our daily operations and cooperation with our customers and partners continue as usual in both companies.
Protrol will operate under the name Ensto Protrol AB, and Torbjörn Karlsson continues as Managing Director.
Protrol Engineering AB is not affected by the transaction.
It is always nice to welcome new customers - however, it is extra rewarding to sign a framework agreement with our existing customers again. We are very grateful for continued trust.

New expandable fault detector
IPC4020 is our newest fault detector for overcurrent and earth faults with integrated remote terminal unit functionality.
The basic version is designed for a typical secondary substation with up to four objects. It can also be ordered with expansion. With expansion it can perform fault detection of three separate objects.
In the Nordics, Protrol is well knowned to have the most efficient solution to identify earth faults in high impedance grounded networks.
The method is also useful in isolated networks, a fact that was thoroughly discussed in a seminar arranged by State Grid in September. Protrol is grateful to the hosts and all the interested listeners that participated during the seminar.

Automatic Fault Isolation and Power Restoration in Härryda Grid
Protrol has together with Härryda Energi in Sweden performed primary faults in Härrydas "Self-sectionalizing grid", an open loop with eight secondary substations equipped with circuit breakers and distributed fault isolation.
IPC, the detectors with remote terminal function, identified the faulty cable segmen fast and distinctly, allowing the circuit breakers in the proper secondary substations to isolate the fault, before the feeding primary substation operated. Finally the open loop was closed, keeping power to the end users.
