Why do I need a Vector Diagram?
Modern reference standards and calibration devices have usually a graphical function to show the relationship between the voltages and the currents. -
What are harmonics ?
Generally a harmonic is a integer multiple of the fundamental frequency (nominal fn). When we have a fn of 50 Hz, the 3rd harmonics is traveling with 150 Hz. We... -
Calculating Apparent Power
There are two commonly used methods to calculate the apparent power (VA). The traditional method is the vectorial calculation.
Vectorial vs Arithmetic Method -
What is Maximum Demand Measurement?
Demand is a measure of average power consumption over a fixed time interval. Maximum (or peak) demand is the highest demand recorded over the billing period. -
Technical vs Non-Technical Losses
Technical losses are coming from current flowing in electrical installations. They can not be avoided, but reduced by proper installation. Technical losses can be calculated.
