Connection
To safely use of CSPF-100, it is important that people installing or handling it, follow the usual
safety precautions.
•
Care must be taken with the capacitors, which may be charged and may discharge even after
voltage is removed. Ensure that the capacitors have had time to discharge.
•
The current transformer (CT) to be installed at a point where all of the load currents to be
corrected plus the capacitor current are passing. The CT must be installed in any one of the
three phases (Refer Connection Scheme).
•
The device must be connected to a power supply circuit and capacitor bank connections
protected with fuse of suitable rating.
•
Make sure that correct discharge resistors are fitted to capacitor bank terminals for safety
reason. They are required for discharging capacitor voltage.
