RIK V
0-5V/0-10V Rogowski Coil Integrator
Chapter 1: Overview
1.1 Overview
The Rogowski Integrator (RIK V) is designed to provide users with an easy to install, plug and
play, retro󳆂t solution that can be used with any power meter or equipment with either 0-5Vdc
and 0-10Vdc current input from a Current Transformer(CT). The flexibility of the Rogowski
Coil CT's reduces the complexity and allows it use to be used for a variety of applications and
con󳆂gurations where special constraints may limit the use of other CT solutions. The RIK is a
con󳆂gurable unit that can measure current from 2.5-60000A making it ideal for any system that
operates at both 50Hz and 60Hz further adding to its 󳆃exibility.
1.2 What's Included
The Rogowski Coil includes either the single channel or three channel integrator unit which
contains the seven con󳆂gurable CT ratios for each channel. The integrator unit can be surfaced
mounted or mounted on a standard DIN rail.
Rogowski coils that will measure the current and the 24Vdc power supply to power the
integrator are sold separately.

RIK V
0-5V/0-10V Rogowski Coil Integrator
The installation of the RIK V integrator requires the user to simply connect the Rogowski coil CT
(sold separately) to the integrator and wire the 0-5/0-10V output to the power meter or electrical
equipment which will receive the signal. If the system is single phase or there are two phases
only the phases that need the CT will need to be connected to the input of the integrator.

RIK V
0-5V/0-10V Rogowski Coil Integrator
Input:
The provided Rogowski coils are the input to the integrator. Connect the Rogowski coil leads
to the input channel on the integrator. The white leads of the CT are the positive wire and the
brown lead is the negative wire.
• Connect the white lead to ‘IN+’ or ‘RCT+’ and the brown lead to ‘IN-’ or ‘RCT-’. The Shield of
the Rogowski coil should be left 󳆃oating. Open the coil by pulling apart the black connector
of the CT.
• Open the coil by pulling apart the black connector of the CT.
• Install the CT around the conductor to be measured. Arrow on the Rogowski coil connector
should be point to load.
• Re-attach the coil together.
• Repeat above steps if using more than one CT.
Ensure that the CT connected to each channel of the integrator is around the correct phase/line
voltage.
Output:
Connect each output channel to the meter or equipment with 0-5V/0-10V input.
• 'OUT+' is to be connected to the positive input terminal of meter.
• 'OUT-' is to be connected to the negative input terminal of meter.
Power Supply: (Sold Separately)
The RIK V requires 24Vdc power to operate. There is a 100-240Vac (50/60Hz) power adapter that
is included to provide this power.
• Connect the input power supply that is between 100-240Vac to the 'L' and 'N' terminals of
the power supply.
• Connect the DC output of power supply to the RIK's '24V+' and '24V-' terminals.

Chapter 2: Hardware Overview
2.3 Conguration
One or three sets of dip switches are used to con󳆂gure corresponding current ranges with
output ratings.
When the dip switch is in the up position the dip switch is considered to be O󳆁. When the dip
switch is in the down position the dip switch is considered as On.
Con󳆂gure each channels dip switches to output the desired range. Dip Switches 1 and 2 will
determine the output signal of that channel.
Note: Dip Switch #3 is not used.
For example to measure current rated for 1000A with a 0-5V output signal dip switches 1 and
2 will be con󳆂gured in the 'ON' position whiles dip switches 4 through 8 for the three channels
must be con󳆂gured to be 'OFF', 'ON', 'OFF', 'ON' and 'OFF' respectively.
• Enter this current ratio into the meter or equipment so it can read accurately from the
integrator.

2.4 Measurements
For each current range the integrator will be able to measure the current from 0.5% up to 120%
of the rated current. That is when the integrator is con󳆂gured to measure a current rated for
1000A it will measure the current from 5A to 1200A. The integrator will output 5A at the rated
current of 1000A and will output its maximum of 6A at 1200A.
The table below provides all the ranges of current that can be measured for each range.
Primary INput (ARMS) Sensing Range (A) Output
500 2.5 to 600 0-5V or 0-10V @500A
1000 5 to 1200 0-5V or 0-10V @1000A
2500 12.5 to 3000 0-5V or 0-10V @2500A
5000 25 to 6000 0-5V or 0-10V @5000A
10000 50 to 12000 0-5V or 0-10V @10000A
25000 125 to 30000 0-5V or 0-10V @25000A
50000 250 to 60000 0-5V or 0-10V @50000A
