The UMT 560 multi transducer and analyser is used for a permanent analysis of electricity supply quality in compliance with the SIST EN 50160 standard. Records are stored in the internal memory for the period of the last three years. Moreover, more than 100,000 deviations of the measurands from the standard values are stored, which enables finding eventual reasons for the problems in network. Optional limits and required quality in a monitored period can be defined for each monitored characteristic.
The transducer measures and records the following characteristics:
- Frequency deviations
- Voltage deviations
- Voltage clips
- Voltage interruptions
- Voltage unbalances
- Over-voltages
- Fast voltage changes
- Flicker intensity
- THD
- Harmonics
