Engineers often come across complicated issues related to power distribution. When a device or machine does not work to its optimum or a circuit keeps tripping under load, one of the suspects when the usual possibilities are ruled out is the quality of the signal.
Power quality analyzers from Fluke or other manufacturers are used to study various electrical parameters such as flicker, inrush current, imbalances between current and voltage. These devices are also excellent tools to measure harmonic currents, voltage value swells and dips, amperage and most importantly the voltage. The huge amounts of data collected by the technician will help him point to a cause of the problem and take necessary remedial steps.
Power Quality Analyzers from Fluke are usually inbuilt with several safety features. Vendors such as Tridinamika have an excellent selection of analyzer devices for all kinds of use and serve most of Indonesia.
There is a lot of planning involved before the actual analysis is undertaken. An experienced engineer will usually make a sketch of the circuit and mark out the measurement points. The data need to be read and interpreted accurately; else the entire exercise will be futile. Usually the data can be transferred to a device such as laptop for a detailed analysis later. The latest generation of power quality analyzers come with several inbuilt features that help the engineer identify many issues immediately. It is important that the technician exploits all the features of the device to get the best analytical result.
