A breakdown (collapse) in an electrical energy supply network causes large fi nancial losses for both the network operator and the consumer. Therefore, it is essential to detect a threat as early as possible so that measures can be taken to prevent such a breakdown.

The new CPR-D Collapse Prediction Relay can help to detect network breakdowns at the earliest possible stage. Collapses in electrical supply networks can be explained using the theory of non-linear dynamics, bifurcation theory and deterministic chaos.

The main use for Collapse Prediction Relay technology is in high voltage and extra-high voltage networks.
Various methods are available for the early recognition of critical network situations, which can be used sequentially, simultaneously or independently of one another.
