Latest Blog Posts for Power Quality In Electrical Systems
- EFFECTS OF HARMONICS ON CAPACITORSThe Effects of Harmonics on Capacitors include additional heating - and in severe cases overloading, increased dielectric or voltage stress, and unwanted losses. Also, the combination of harmonics and capacitors in a system could lead to a more sever...
- STATIC SYNCHRONOUS SERIES COMPENSATOR (SSSC)Static Synchronous Series Compensator (SSSC) is a modern power quality FACTS device that employs a voltage source converter connected in series to a transmission line through a transformer. The SSSC operates like a controllable series capacitor and s...
- FERRORESONANCE PREVENTION TUTORIALSFerroresonance Prevention Tutorials deal with strategies that electric utilities and end-users could implement to minimize occurrence of the power quality phenomenon. These practices are based from the fact that ferroresonance usually happens with li...
- FERRORESONANCE AND TRANSFORMER CONNECTIONSFerroresonance and Transformer Connections are related as such that the latter is a significant factor to the occurrence of the former during loss of phase or open phase conditions. There are certain transformer configurations that are more susceptib...
- POWER QUALITY BASICS: FERRORESONANCEFerroresonance is usually described as an irregular and chaotic type of resonance. This phenomenon occurs because of the nonlinear characteristic of iron-core (saturable) inductors - ferromagnetic material such as a transformer. Ferroresonance is oft...
- POWER QUALITY BASICS: VOLTAGE NOTCHINGVoltage Notching is described by IEEE as a recurring power quality disturbance due to the normal operation of power electronic devices (i.e. rectifier), when current is commutated from one phase to another. Conventionally, the current waveform is use...
- EFFECTS OF HARMONICS TO ELECTRONIC EQUIPMENTThe Effects of Harmonics to Electronic Equipment are experienced in various ways depending on the type of device - from slight to serious consequences. Ironically, it is a known fact that most electronic equipment is prone to misoperation due to harm...
- DELTA CONVERSION ONLINE UPSon Nov 2, 2011 in PQ Devices UPSDelta Conversion Online UPS is a modern innovation that eliminates the disadvantages of the traditional double conversion online UPS. The enhancements are based on having a delta inverter and allowing bidirectional power flow. Today, this design is t...
- MOTOR-GENERATOR (M-G) SET FOR IMPROVED RIDE-THROUGHMotor-Generator (M-G) set is basically a combination of a motor and generator, although it is physically different from an ordinary electric motor that is attached to a separate generator. It has many practical functions that generally involve conver...
- EMTP-RV: REFERENCE FOR POWER SYSTEM TRANSIENTSEMTP-RV is a powerful and dedicated software for the simulation and analysis of transients in power systems. It provides an extensive variety of system modeling capabilities covering electromagnetic and electromechanical oscillations ranging in durat...
