AUROW
AUTOMATIC POWER FACTOR CONTROL SYSTEM
SPECIALLY DESIGNED FOR POWER INDUSTRIES
GERMAN TECHNOLOGY
|
AUROW POWER SYSTEMS is an electrical term used to rate the degree of the synchronization of power supply current with the power supply voltage. This term is often misunderstood
By ourselves or simply ignored.
|
It is important that we clearly understand the meaning of "POWER FACTOR" and its effects in the electrical supply systems are given below :
- A low power factor can increase the cost of power to the user
- A low power factor can increase the cost of power transmission equipment to the user
- A customer may request assistance in selecting equipment to correct the low power factor
- Over correction of power factor by the addition of capacitance is sometimes dangerous to motors and the driven equipment
Penalty and excess demand charges due to low power factor
