• EFFECTS OF HARMONICS ON CAPACITORS
  on Jun 17, 2012 in Capacitors Power Quality Harmonics
  The 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)
  on May 31, 2012 in PQ Devices SSSC FACTS Devices
  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 TUTORIALS
  on Apr 30, 2012 in Ferroresonance Overvoltage Single-Phasing
  Ferroresonance 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 CONNECTIONS
  on Mar 24, 2012 in Ferroresonance Power Quality Overvoltage Transformers
  Ferroresonance 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: FERRORESONANCE
  on Feb 29, 2012 in Ferroresonance Power Quality Overvoltage
  Ferroresonance 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 NOTCHING
  on Jan 29, 2012 in Power Quality Harmonics Voltage Notching
  Voltage 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 EQUIPMENT
  on Jan 1, 2012 in Electronics Power Quality Harmonics
  The 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 UPS
  on Nov 2, 2011 in PQ Devices UPS
  Delta 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-THROUGH
  on Oct 30, 2011 in PQ Devices Motors Generators
  Motor-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 TRANSIENTS
  on Oct 27, 2011 in Transients Software EMTP-RV
  EMTP-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...
