We have, together with interested customers, developed a new generation of over voltage protection for signal cables (RS485).
The first installations will be made before thunderstorm season for maximum protection when it is needed most.
New Frame Agreements Fault Detectors
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.
Protrol moves to larger and more adequate facilities in Mölndal. Our new address from the 7th of December 2018 is:
Protrol AB Alfagatan 3 431 49 Mölndal SWEDEN
Protrol's automation gets the front page in ERA
Finally it has been released - ERA's latest issue which features Protrol och automation in the distribution network!
Here are some comments from the article:
"- It has provided very good results. Earlier, localising and removal of faults could take from 20 minutes up to several hours. Today it takes maybe two minutes to localise, says Hakan Ünal" (Göteborg Energi)
"- Protrol has developted special software algorithms that manages to use the phase currents in a very sensitive way. When you do not need to measure the voltage the product and the installation becomes become less complicated, that affects costs, says Ferruccio Vuinovich" (Göteborg Energi)
"- This is definitely a new way of thinking. We have not heard of other utilities that uses decentralised automation on the signal cable networks, he says (Hakan Ünal)"
Protrol is the supplier of the centralized protection and control system SASensor for Ellevio's new substations Segmon and Svänkviken. This is the first time this type of type of protection and control system is used in the region of Värmland, but it is not new for Ellevio. Naturally, all configuration and commissioning is included in the delivery.
Protrol is the single supplier that was qualified in the framework agreement for fault detectors that recently was made by Göteborgs Energi AB.
Protrol supplies both separate fault detectors to contractors supplying new secondary substations and pre-manufactured cabinets for refurbishment of existing stations.

Protrol has introduced a new version of the appreciated fault detector IPS2. With its high sensitivity for earth faults in the network and simplicity of use it reduces the outage times drastically. With fault detectors in the secondary substation, information about the faulty cable segment is available immediately, and it is possible to quickly isolate the fault without trial energizations.
The latest version has 24 VDC supply voltage, configurable in- and outputs and IEC 60870-5-101 communication. This makes it specially suitable for secondary substations that are or will be connected to the control center.
The algorithm for earth fault detection does not require any voltage transformer which makes IPS2 a very cost efficient fault detector with high sensibility for pass-through faults, also in network with low earth fault currents.

Primary earth fault tests with IPC4012 in Lithuania
IPC4012 was today verified in primary earth fault test. A couple of IPC4012 units were located in both forward and backward bays with respect to the fault.
The units were supervised by Protrol's office in Sweden through the mobile network.
Several earth fault tests were performed with varius conditions, and the faults were identified as expected. The test was performed in Lithuania by Protrol's local partner FIMA in ESO's network.
9-12 May 2017 it is time for Elfack again. We will be in the exhibition boot B09:82, and we would be delighted if both existing customers and potential new customers can visit us for a chat!
