Maximum safety for people and machines – with RITTER protection technology. 

Minimise the risk of equipment and network incidents, avoid lengthy and costly outages, and maximise the safety of operating personnel. Our protection for high, medium and low voltage networks provides optimum safety for humans and technology in the areas of energy, water, industry, transport and buildings. For us, strong protection begins as early as the planning stage.

Whether it is switching fault protection concepts or protection concepts for different power grids: we offer professional engineering and ensure a transparent project process, comprehensively defined and listed in technical requirements, specifications and tender documents.

Protection of switchgears and sensitive data - also for projects involving high voltage.

Our range of services includes the manufacture and supply of switchgears – including relevant protection technology. With our solutions for projects, including those that involve high voltage, we reduce the risk of interruptions and protect sensitive data. Our devices will be tailored to your needs after testing your system. We can also take over the regular maintenance of the protective components for you.

In the video we will inform you about our complete range of services in the field of protection technology. 

Plans, tables and audit logs - all your data at a glance.

Do you want specific figures? We calculate short-circuit currents, load flows and voltage drops, as well as protective setting values, for different power grids. We will gladly create graduated schedules or protection setting tables using NEPLAN, the professional software from ABB.

In addition, our portfolio includes the parameterisation of protection relays for busbar, transformer and line differential, motor, overcurrent and distance protection devices of different makes. The computer-assisted secondary and primary testing of the activated protection functions is carried out by means of Omicron test equipment – test protocol included.
