CSPF-100 : Power Factor Controller
If the system is not put into service immediately, it must be stored in a dry location at a temperature
0 0
between -10 C to +70 C
Please check the phase & polarity while inserting the CT wire, Wrong polarity or phase can cause the
wrong result (may cause wrong power factor measurement)
On receipt of the device check that it has not been damaged during delivery and the model supplied is
the same as the one ordered
For the safe use of CSPF-100, it is vital that those persons installing or handling it, follow the usual
safety procedures as well as specific warnings contained in the QRG
Installation, maintenance and inspection of the product should be performed by the qualified staff
Verify that voltage range for the device supplied matches the mains voltage where it is to be installed
Do not install CSPF-100 near to source of heat and do not expose to a excessively humid atmosphere
Verify correct terminal connection when wiring. Wrong connection may cause damage to the product
Check that the secondary windings of external CT is short-circuited when they are not terminated to
CT terminals of CSPF-100. An open secondary windings of a loaded CT may cause dangerous over voltage.
Turn off the all power sources connected to the device, before installing or services to prevent
Bear in mind that when the device is in operation, the terminals may be dangerous when touched
electric shocks, injury or damage to persons or property

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.

Note: C/k ratio will not be calculated properly or can be miscalculated when load is unstable and varies quickly,
This may cause improper compensation. The better option is to disconnect the load and then start this process.
C/k will be calculated and stored in the memory. The calculated value can be viewed in C/k ratio setting ( ) under
programmable parameters.
In Auto C/k setup C/k value will be calculated based on first capacitor step rating. This capacitor is the smallest
size among the all capacitor steps connected.

1. CT polarity need to be checked.
2. Refer the section connection scheme and
verify the phase angle to be set for various wiring.

Target Cos phi is within
limit Conn.scheme is not
as per phase angle set
All the capacitor steps
were switched On. But
target cos phi was not
achieved
1. Verify the set target cos phi.
2. Set the phase angle as per the connection
scheme.
1. Check whether installed rating of capacitor
sufficient for present load and target cos phi.
2. Refer the C/k ratio value in basic setting in
page 8.
Trouble Shooting Points
No capacitor
steps are
switching
though
present load
is inductive
CSPF-100 is in Manual
Mode / Loose
Connection to capacitor
contactors / Target cos
phi is within defined limit /
wrong setting of C/k
value / A parallel
connection from CT
secondary is connected
to any ammeter installed
1. In Manual mode Auto/Manual Led will be ON
in Manual mode user has to press up/down key
to connect/disconnect capacitor bank(with
ON/OFF delay). If Manual mode operation is not
required switch to Auto mode.
2. Correct if it is loose connection.
3. Check the target cos phi and C/k value set
under programmable parameters.
4. Verify whether connected capacitor power
ratio is as per selected program selection or not.
5. Check that if set phase angle value is correct
for present connection.
6. All measuring instruments in current path
must be in series.
