ISKRA MC 760 Network Analyzer
The MC 760 network analyzer is used for permanent analysis of electric voltage quality in compliance with the SIST EN 50160 standard. Records are stored in the internal memory for the period of the last 7 years. Moreover, more than 170,000 deviations of the measured quantities from the standard values are stored, which enables finding of eventual reasons for the problems on network. Optional limits and required quality in a monitored period can be defined for each monitored characteristic.
The meter 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
Features:
