Deltameter 5
The Deltameter 5 is a measuring device for indicating the voltage difference between two phases. When inter-connecting different medium voltage systems, protective devices may be actuated as a result of incorrect phase and voltage levels, although phase relationship tests with IEC 61481 phase comparators have indicated "phase coincidence". In cases like these, the Deltameter 5 can be used to supplement the phase relationship tests with phase comparators. It indicates the quantitative voltage difference between two phases on a four-digit segment display with a resolution of 10 V. Thus the Deltameter 5 provides a highly precise decision-making tool for imminent switching operations.
