Polyteck Building Services electrical testing will help you to save money.Â You pay your electrical bills as the sum of all kW you use times the hrs you run your appliances. (kWh)
Mathematically it is:
- PÂ =Â VrmsÂ IrmsÂ cosÂ Ï†
- PÂ Â Â Â Â Â is the real power in watts [W]
- VrmsÂ is the rms voltage = Vpeak/âˆš2 in Volts [V]
- IrmsÂ Â is the rms current = Ipeak/âˆš2 in Amperes [A]
- Ï†Â Â Â Â is theimpedance phase angle = phase difference between voltage and current.
- PFÂ = |cosÏ†|Â (PF=Powerfactor)
So the kWh you pay for depend linear on the â€œPowerfactorâ€. The power factor PF is equal to the absolute value of the cosine of the apparent power phase angleÂ Ï†(also impedance phase angle).
The Powerfactor normally is bigger than 0,9. But if it is below, you lose more than 10% of the power that you pay for.Â Polyteck Building Services has the powerfactor analyser tools to check the powerfactor of your installation.
Polyteck Building Services will adjust the power factor to save your money with power factor correction
With Power factor correction Polyteck Building Services adjusts the electrical circuit in order to change the power factor near 1. The result is that the reactive power in the circuit is reduced and most of the power in the circuit will be real power. Normally the power factor correction is done by adding capacitors to the load circuit, when the circuit has inductive components.
