Our comprehensive portfolio of protection technology enables reliable grid availability in the voltage ranges of 10 kV to 110 kV. The protective and control devices can be used in, for example, single and double busbar applications, as well as radial, looped, and meshed grids. They can also be used in insulated, compensated, rigid, and low-resistance grounded grids.

The front panels of the protective relays offer numerous options for interaction and for visualizing the current states.
The displays can be configured as needed and offer sufficient space to show system graphics, tables of measured value, and virtual LEDs.
Numerous navigation and operating keys allow easy control on site. The USB service interface on the front enables easy connection to the protective relay.
The operating software makes device configuration quick and easy. For example, during step-by-step commissioning, dependencies between entered settings are taken into account and grayed out.
In addition to the general device settings, the interfaces to the primary technology and the protective functions are also configured.
In addition to I/O matrices, editors for creating the logic and visualization also provide support during the configuration.
Direct communication to a control system or a higher-level control engineering system is possible via various communication options.
With our comprehensive service portfolio, we help you digitalize and optimally adapt and expand your grids. By using highly available and technically mature products and solutions, we optimize the reliability of the supply. We provide you support from the planning phase through to implementation.
The protective relays of the KOMBISAVE+ product family are perfectly suited for use in the distribution grid. Motors, transformers, cables, and lines can be protected in switching devices with single or double busbars.
The devices include a large range of functions, from overcurrent protection through to QU protection, distance protection and line differential protection, synchro check, and automatic reconnection.
POWERSAVE is a compact and powerful protective relay with a
full range of protection, control, and measurement functions. With the optional integrated power management for direct triggering of the circuit breaker, the device solution is independent of the external power supply.
The combination of energy management and distance protection functions makes the protective relay indispensable as blackout protection.
In just a few steps, identify the right system for you for reliable protection technology.
