Why Power Transmission Cables & Lines are Loose on Electric Poles & Transmission Towers?

Why Power Transmission Cables & Lines are Loose on Electric Poles & Transmission Towers?

INTRODUCTION Transportation of people, goods and services today is no longer a problem as technology is fast growing. Distance is neither a barrier nor a problem. Just as people, goods and services are easily transported across a distant destination, ELECTRICITY is no different. Electricity can be transported over a long distance. But unlike goods, electricity requires a medium through which …

Causes of low Power Factor

  Causes of low Power Factor The main cause of low Power factor is Inductive Load. As in pure inductive circuit, Current lags 90° from Voltage, this large difference of phase angle between current and voltage causes zero power factor. Basically, all those circuit having Capacitance and inductance (except resonance circuit (or Tune Circuit) where inductive reactance = capacitive reactance …
