about us

25 years anniversary of NSE AG

From an engineering office to a high-tech company in the field of intelligent protection and control systems, we are proudly celebrating our 25th anniversary.

We have been able to continuously expand our core DNA, current-transformer-powered protective devices, with many new technologies.

Today a device consists of 15% hardware development and 85% software. Network technology, cyber security, communication, measurement and freely programmable controls are just as much a part of our repetoir as protection technology.

Our know-how in the area of ​​protection is based not only on 25 years of development, but also on the knowledge of former colleagues from ABB Schutztechnik Baden and Schutztechnik Sprecher&Schuh from Aarau: a concentrated load of know-how.

At this point we would also like to thank all employees, including those who have actively made the company what it is today in the past and of course the many long-standing and loyal customers - without whom we would not exist.

AXC F XT PMP
NSE is developing the PMP module, an expansion module for the PLCnext technology platforms, on behalf of Phoenix Contact.
The high-precision protection and measurement module is specialised for use in the wind energy industry.

Discontinuation of DIGISAVE and KOMBISAVE

POWERSAVE

The POWERSAVE combines the strengths of the two devices DIGISAVE and KOMBISAVE+. As a compact and powerful IED with distance protection function and the optionally integrated power management, the first devices find their place at the Technische Betriebe Glarus.

KOMBISAVE+

The KOMBISAVE+ is brought up to date with a hardware and software renewal. The first units leave production for Stadtwerke Winterthur and Germany.

PHOENIX CONTACT takes over NSE AG
PHOENIX CONTACT Group, a leading global manufacturer of components and systems for electrical connections as well as industrial automation has taken over NSE AG on Mai 31, 2017.
Press release (German)

Start development of DIGISAVE V2

Sale of the DIGISAVE RB Traction Protection Relays
After having produced DIGISAVE devices for around 10 years, a completely reworked version was brought onto the market for the first time as a 16.7-Hz traction current protection. The Austrian Federal Railways (ÖBB) was the intended customer. The devices were to be used as autonomous protection relays supplied with transformer power and equipped with capacitor energy blocks to be tripped in the event of a blackout.

Market Expansion in Germany
Our partner SAE IT based in Cologne successfully implemented combined protection and field control units from our company into the public utilities in Heide, Germany. This led to us getting a toe into markets abroad.

Sale of the First KOMBISAVE Devices
Modern combined protection and field control units left the plant and were installed in UW Münchenstein EBM, Switzerland.

The Transformation of NSE AG
NSE GmbH transformed into NSE AG with its share capital increasing to 200,000 CHF.

Production of High-Current Sources HI2000
A high-current check source built on a transformational principle was released to check the current transformers and primary protection relays. The source generated testing currents of up to 2000 A.

DIGIMUT Retrofit
NSE AG developed a conversion kit to use the mechanical primary relay and implemented this as a prototype in Zurich's EW. The kit included both a numerical protection relay supplied with transformer power and a special 12/24/36 kV current transformer. The interface to the circuit breaker consisted of its own specifically developed TRIP mechanics.

2004

Start of the DIGISAVE Production Line
The first DIGISAVE numerical protection relays left the Wohlen plant in Switzerland and were headed to Lenzerheide in the Swiss canton of Graubünden, where they joined the long-term production of protection relays in Switzerland by Sprecher&Schuh.

2003

Construction of Protection Relay Production SAVE-TEC / Apparatus Manufacturing in Wohlen
A production line for electronic protection relays (SAVE technologies) was installed and built in Wohlen.

2001

Wohlen AG Headquarters
The office building in Wohlen AG moved to Bremgarterstrasse 54. The headquarters were relocated to Wohlen. Start of the development activity on the numerical protection relays

1999

NSE GmbH
On 06/30/1999, NSE GmbH was entered as a cooperate entity in the Swiss Commercial Register. The focus was on design work/engineering services in medium-voltage and the modernization of substations.

1998

Engineering Office
The freelance engineering services of Andreas Aebersold MEng in Dottikon/AG at Luegetenstrasse 1 were taken on.
