EHIGHWAY. At 28. and April 29, the two rectifier substations were inspected and cleaned as part of the scheduled first maintenance measure.

Employees of Nahverkehr Schwerin GmbH took some of the substations completely off the grid in order, for example, to be able to clean the dust from the 30kV transformers. During the functional tests of the safety equipment, particular attention was paid to the circuit breakers of the line feeders, which de-energize the overhead contact line in the event of a fault or hazard.
