Area of application Power Quality Measuring and monitoring the electric power quality (EPQ) is a crucial tool for energy producers, grid operators and consumers alike to document supply reliability and voltage quality on the one hand and to prove compliance with emission limits on the other hand. But also to analyze and thus avoid downtimes and failures. Your benefits at a glance > Characteristics according to the standard IEC 61000-4-30 class A > Reducing energy costs > Assuring supply > Documenting voltage quality > Observing emission limits > Analyzing faults > Meeting quality...

With the modular ibaPQU-S system, it is possible to record data from the plant together with the calculated quality characteristics and measured raw values centrally in ibaPDA. This enables users to thoroughly evaluate all data, recognize contexts and thereby determine the root-causes of faults or quality variations. Moreover, the data provide important information about the dimensioning of the plant and its optimal operation. Consumers are obliged to quality Electricity consumers influence the grid quality for example by power electronic devices, e. g. for frequency-regulated drives. Grid...

The iba system provides a wide range of functions to monitor and optimize electrical power facilities: continuous monitoring of the power quality in energy grids, use as digital fault recorder (transient fault recorder) and integration of the protocol standard IEC 61850. The possible applications complement each other and can be operated in parallel. Proving electric power quality in line with standards Electrical power quality (EPQ) is defined by characteristics such as frequency, height, curve profiles and symmetry of the supply voltage. It is adversely affected to an ever greater extent...

ibaPQU-S High voltage 110 kV Example of monitoring of the power quality using ibaPQU-S in the iba system Analyzing fault causes The process data acquisition system ibaPDA connects ibaPQU-S into the overall plant and process monitoring. Thanks to ibaPDA‘s broad connectivity, it is possible to acquire the measured values from various sources and sample them synchronously. Using special mechanisms, the grid synchronous measured energy values are harmonized with the time synchronous process values. So the electric power quality parameters can be correlated with the plant’s operating mode. The...

Examples for measurement and display with ibaPQU-S The following examples show measurements with ibaPQU-S. The display of the characteristic values in ibaPDA allows to draw conclusions about certain events or a possible failure and its cause. Phasor and Spectrum View In the phasor view, voltages and currents are displayed according to magnitude and phase position. So the user recognizes the current load situation. The spectrum diagram shows how much the consumers are burdened with harmonics. Both diagrams allow conclusions on the consumer structure. Power Quality Monitoring with ibaPQU-S...

Example: commutation notches Commutation notches are caused, for example, by power converters. For the peaks being very steep but in fact also very brief, the effective value is only marginally changed. But nonetheless, other consumers can be interfered in their function by this effect. Thanks to the high-resolution (raw) values, this event is also recognized as an error and recorded by ibaPQU-S. Example: voltage drop The signal trend shows a voltage dip and the reaction of the effective values of the conductor currents to this event. Further analysis allows to derive statements on the...
