AUTOMATIC POWER FACTOR CORRECTION RELAY
This document contains the latest technical information about Automatic Power
Factor Correction Relay Newton+ which is a micro-controller based KVAR controller.
The product, Newton+ is sophisticated electronic equipment and, the user is advised
to read this User’s Manual carefully before attempting to install or operate the
equipment.
General
The relay is meant for flush mounting in a panel for connection to the electrical
system.
The relay is the `intelligence' which controls the automatic system for correction of
the power factor. It senses the power factor by taking the ratio of the true rms KW
and KVA of the system, for any one phase of the three phase electrical system .
NEWTON+ provides auto phase sequence and polarity detection in programming
mode. So same or different phase can be use for voltage and current inputs. For
correct operation of relay, however, there are some minimum system requirements
to be met. Unless the various points in the system which are mentioned below are
correctly setup, proper operation of the relay cannot be expected.

Operational Details
There are two types of Modes in this unit such as Programming Mode and Run
Mode. Once the unit is supplied power 240 V AC to the Single phase supply, the unit
enters into Run Mode.
Press
key for about 4 to 5 seconds continuously and then the unit will enter into
Programming Mode showing “PROG MODE PRESS^”, now press key and it will
show first programming mode parameter “MCT_PRI” and “P” starts blinking which
indicates unit is in programming mode. Set “>” by using and to desired
parameters which need to modify. Press key. Immediately “>” starts blinking, it
shows that the parameters can be changed. Set the parameters by pressing key
and key according to your desire and then, press key to confirm the setting.
To set for all the programmable parameters, press key or key to receive the
desired parameters and set such as steps before. To exit the programming Mode
and return into Run Mode, press for about 4 to 5 seconds continuously. However,
key operation is not being done for about one minute, the unit returns into Run
Mode.
Backlight will be dimmed after 5 minutes. On any key press event LCD will have full
brightness.
The Programming Mode contains the following programmable parameters.
1. MCT_PRI
In order to give actual current values in your system, the Main CT Ratio between the
primary and secondary current should be set. The Main CT primary can be set from
5A to 5000A.
2. MCT_SEC
In order to give actual current values in your system, the Main CT Ratio between the
primary and secondary current should be set. The Main CT secondary can be set to
1A or 5A.
3. PT_RATIO
The unit has PT Ratio on the basis of HT PT installations in between primary and
secondary voltages. PT Ratio is selectable from one of the following values: 1,
3.7727, 4.000, 6.2727, 30, 60, 100, 200, 300, 600, and 1200.
NOTE: If PT Ratio selected other than ‘1’, unit considers it as HT sensing.
4. CONTROL
For PF correction, there are four types of Control action such as FIFO , VAR,
BINARY and Straight FIFO (SFIFO) which are also selectable at site. In case, the
CONTROLactionis selectedtoVAR, capacitorCTand AUTOSENSING parameters
are applicable at site. However, both the two parameters will not be applicable in
case of FIFO, Straight FIFO (SFIFO) andBinary

5. CAP_CT_ENB
NEWTON+ supports VAR control action with/without capacitor CT. However it is
recommended to use capacitor CT. In VAR control action mode, using capacitor CT,
proper Bank KVAR can besensed.
CCT_PRI (Capacitor CT Primary) and CCT_SEC (Capacitor CT Secondary) will be
enable in case of CAP_CT_ENB is set to YES.
6. CCT_PRI
In order to sense proper capacitor KVAR based on capacitor CT, the Capacitor CT
Ratio between the primary and secondary current should be set. The capacitor CT
primary can be set from 20A to 2000A.
7. CCT_SEC
In order to sense proper capacitor KVAR based on capacitor CT, the Capacitor CT
Ratio between the primary and secondary current should be set. The Capacitor CT
secondary can be set to 1A or 5A.
8. SET_PF
The desired PF can be set to either Lead or Lag side according to your requirement
In case of LAG, the PF could be set from 0.800 to 1.000. In case of LEAD, the PF
could be set from 1.800 to 1.999. e.g., the PF to be set for 0.998 LEAD should be set
as 1.998.
9. SWITCH
In case, Normal (Contactor) OR Fast (Thyristor) switching is site selectable.
10. STAGE
NEWTON+ supports up to 8 capacitor bank Stages. For user’s system requirement,
thenumber of Stages can beselected from 2 to 8soas to operate the KVAR control.
11. OPERATION (OPER.)
If you have Solar panel installation at your site, select Solar else select Normal mode
for proper controlaction.
NOTE: This is optional feature.
12. SCROLL
The Run Mode displays freeze by default which starts displaying system PF and is
also freely programmable from 5 to 12 seconds so as to scroll to each parameter on
a cyclic basis. If the SCROLL is set to 0, the displaywill freeze.
13. TIME DELAY
This is one type of digital dead band in case of VAR control action. Time Delay is
freely programmable from 1 to 10 in Fast (Thyristor) and from 40 to 180 in Normal
(Contactor) switching.
14. ON DELAY
In case of FIFO or Straight FIFO (SFIFO) control action, On Delay is freely

programmable from 1 to 10 in Fast (Thyristor) and from 10 to 20 in Normal
(Contactor) switching. Either target PF is set on LAG side and system PF falls below
target PF or if target PF set on LEAD side and system PF goes above target PF in
LEAD side, the unit checks whether the switching capacitor could be persistent or
no. If target PF isnot achieved, the relayswitches on thecapacitor bankaccordingly.
15. OFF DELAY
In case of FIFO or Straight FIFO (SFIFO) control action, Off Delay is freely
programmable from 1 to 10 in Fast (Thyristor) and from 10 to 20 in Normal
(Contactor) switching. Either target PF is set on LAG side and system PF falls below
0.980 PF LEAD or if target PF set on LEAD side and system PF falls below
OFF_SET parameter in LEAD side, the unit checks whether the switching capacitor
could be persistent or no. If target PF is not achieved, the relay switches off the
capacitor bank accordingly.
16. REF_BANK
The unit will switch ON and OFF the bank number selected by user in REF_BANK,
in order to detect phase sequence of inputs.
NOTE: Make sure to connect three phase capacitor bank on selected
REF_BANK number.
17. CHECK_SEQ
This feature can use todetect phasesequence error and correct all values according
to detection. In order to this feature works, the load current should have a value
greater than zero. The unit will switch ON and OFF the bank selected by user in
REF_BANK, in order to perform auto correct. If load is nonlinear or too many sudden
changes occur in the load during this process, it may not be able to correct the
connection. In this case, user must disable non liner load temporarily and repeat the
process or can manually enter the phase sequencevalue.
18. PHASE_SEQ
User can manually enter phase sequence value if above features fails to recognize
phase inputs due to certain conditions of nonlinear load and etc. phase sequence
value can be set from 0, 60, 120, 180, 240 and 300.
19. MIN. BANK
In case, the need KVAR exceeds 75% of the minimum capacitor bank, the relay
switches the minimum bank on. Hence, the parameter can also be set to 100%
according to your desire.
20. AUTO SENSING
In case, the Autosense is set to YES, the unit switches on all relays one by one. The
bank sizes will also display as they get sensed one by one and the user must
therefore be patient and wait for about 4 to 5 minutes while the autosense is in
progress. This process is vital for the smooth operation of the relay. Once all
capacitor bankscouldbe sensed, the relaywill restartfor control action after a while.

21. M_OPR
This parameter is used to set minimum current required to start control action in
FIFO, SFIFO and BINARY mode. If this parameter is set to "Sensitive" it will do
control action until current goes below 1% of Main CT Primary. If this parameter is
set to "Normal" it will do control action until current goes below 5% of Main CT
Primary.
22. OFF_SET
This parameter can be used to switch OFF banks in FIFO, SFIFO and Binary mode.
If target PF is set on Lag side it will switch OFF banks if PF goes below 0.980 lead. If
Target PF set on the lead side, it will switch OFF banks when PF goes below this
parameters value. Value of "OFF_SET" parameter can be set to 1.780 to
(Target_PF-0.2).
