2 The rangeincludes a number of options to overcome these electrical equipment consists of nonlinear deviceswhich generate harmonics. Examples of thesedevices include the following:- Arc furnaces- In certain cases, transformers, reactors and rotating machines- Domestic appliancesHarmonics are not only found in industrial networks, they can also spread into the distribution networkand cause problems for other power users. Common problems that harmonics can produce include:- Overloading of capacitors , leading to malfunctioning and premature aging- Increased losses, eg.

3 Machines will operate at increased temperatures- Resonance problems between the inductive and capacitive parts of the network- Malfunctioning of control systems- Interference with telecommunication and computer equipment- Disturbances in ripple control systems- High currents in neutral conductorsHarmonics distort the sine wave (50 Hz or 60 Hz) sign which becomes apparent when a distorted sinewave mathematically Equipment containing electronics that control other apparatus. Eg. variable speed drives, soft starters,static compensators, rectifiers, BankQc/Sn > 15% the customer specifies automatic startup or shutdown for the capacitor bank (controlled byrelay).

4 The reactive power of the capacitor bank is split into steps with the possibility of starting orstopping more or fewer steps. The reactive power corresponds to the change in load BankQc/Sn < 15% the reactive power of the capacitor banks is constant and they are started up or shut downwhen a predetermined KVAr value is reached.
