When a small hydroelectric power plant is coupled to the public power grid, the power inverter must be equipped with a grid and system protection device that continually checks the grid quality and immediately decouples the system when a fault is detected. In this way, unintentional isolated operation is prevented, thereby avoiding a dangerous situation for maintenance p...

When running several electrical consumers simultaneously, such as machines with hot-water boilers or building heating systems, it is important to avoid overloading the power grid. Solution The TELE E1IM10AACL10 load shedding relay switches off subordinate consumers as soon as one of the other consumers is switched on. The relay measures current with precision and rel...

Solution: The use of load monitors alone is not possible because the loads vary depending on the temperature and the medium, and the load monitors would have to be continuously reconfigured. The analogue signal from the G2BA400V12A combined with the temperature and medium type allow the customer to create a profile in the PLC and to thereby provide dry running protection...

Solution: If the phase sequence is connected incorrectly when the system is started up, the monitoring relay prevents the screw conveyor from starting. The rotary field could also change at a later point in time, which would cause the screw conveyor to run in the reverse direction and which would cause blockage and possible damage to the system. The monitoring relay also...

If currentless travel tak...

Application The brown-out detector from TELE reliably detects power fluctuations. It detects brown-outs / short interruptions of at least 10 ms, whereby the reaction time of the short-term interruptions is adjustable between 10 ms and 40 ms via potentiometer. Using the brown-out detector prevents undefined states from occuring in switching and control equipment. Sh...
