A Mavowatt from GOSSEN METRAWATT in use<\/div><\/div><\/div><\/div>\n

Introduction<\/h2>\n

One automotive related factory has repeatedly complained about the tripping of overvoltage protection and power outages in some production halls. In order to find the cause and locate the fault, power quality measurements were carried out on production machines on the low voltage side. For measurements and analysis was used a three-phase network power quality analyzer Mavowatt 270.<\/p>\n

Firstly were carried out measurements on the main electrical distribution cabinet in the plant and there were registered frequent complaints about power outages. After that, in a duration of seven days was conducted the measurement of power quality.<\/p>\n

Analysis of measurement data<\/h3>\n

Measurements on the electrical cabinet show that voltage values oscillate at the limit (Un + 10%). At one point, there is a sudden voltage increase, then a short-term voltage interruption and again a voltage increase \u00a0which lasts for more than an hour.<\/p>\n<\/div><\/section>\n
