Lasting solutions for machine output panels.

Machine output panels are the crucial link between the electrical drive and the grid connection point; they are equipped with essential components for controlling and monitoring the electrical machine.

Our connection panels ensure that the required power is always available; they satisfy the most stringent requirements for quality and reliability, and they are very low maintenance.

According to project requirements, current and voltage transformers are installed for the star-point or grid sides. Additional components can include star-point handling components or an excitation transformer. Short-circuits close to the generator can enable very high currents to flow, which entails high electromagnetic forces and thermal effects. These effects can result in damage or destruction of the affected components, which is why fault scenarios are considered in the planning, simulation, and construction of the connection equipment.
