Improve the Power Factor
◆
Connecting an AC Reactor
AC reactors decrease surges in current and improve the power factor on the input side.
Connect an AC reactor to the input side (primary side) in these conditions:
•
To decrease harmonic current or improve the power factor of the power supply
•
When there is switching of phase advancing capacitor
•
With a large capacity power supply transformer (600 kVA or more).
Note:
•
When you connect a thyristor converter (for example, a DC drive) to the same power supply system, use an AC reactor for all power supply
conditions.
•
The main circuit terminal block and the terminal block for the AC reactor have different shapes. The bypass has a European-style terminal
block and the AC reactor has a circular terminal block. Use caution when you prepare the ends of the wires.
A - Power supply
B - MCCB
C - AC reactor
D - Bypass
Figure 3.26 AC Reactor Connection Example
Note:
When you connect an AC reactor to the output side (secondary side), set
C6-02 = 1 [Carrier Frequency Selection = 2.0 kHz]
