Chapter 1: Introduction
1.1 Overview
The Relay-Class 1AR Rogowski Integrator Kit (RIK) is designed to provide users with an easy-to-install, plug-and-play solution that can be used
with any protection relay, power meter, or device with a 1A nominal current input. The exibility of Rogowski Coil CTs reduces installation
complexity and is ideal for a variety of applications or unique congurations where spatial constraints may limit the use of rigid-body CT
solutions.
The integrator kit is rated for class 5P20 (IEC 61869-2). This means that if the primary current is 20 times the rated primary current of the
1AR, it will be able to sense and measure the current with an accuracy of 5%. The 1AR is user-congurable and can measure current from
0.25A to 100kA. Additionally, it can be used on systems that operate at both 50Hz and 60Hz further increasing its utility across industries.
1.2 What's Included
The Rogowski Coil Kit includes a single-phase integrator unit with ve, congurable CT ratios for the current input channel and a 24Vdc power
supply to power the integrator. The integrator can be surface-mounted or DIN rail mounted; the power supply is designed to be mounted on
DIN rail. One Rogowski coil (model RCTxx-1000; available in sizes from 16” to 47”) is required to measure the current and is sold separately.

2.2 Installation
The following steps outline the installation process:
1. Connect a Rogowski coil CT (model RCTxx-1000 in any length) to the integrator
2. Wire the 1A output to the protection relay or power meter which will take the signal
The diagram below illustrates how to connect the integrator.

Input
The Rogowski coil provides the input to the integrator. Connect the Rogowski coil to the input channel on the integrator. Be sure to observe
the correct wire polarity: the white lead is positive (+) and the brown lead is negative (-).
• Connect the white lead to 'IN+' and the brown lead to 'IN-'. The Shield of the Rogowski coil should be left oating.
• Open the coil by pulling apart the black connector of the CT.
• Install the CT around the conductor to be measured. Verify the CT is installed with the CT facing the same direction as the current ow
direction as indicated by the arrow on the black connector.
• Connect the coil back together.
Output
Connect the output channel to the protection relay or the 1A current input on the power meter.
• The 'OUT+' is to be connected to the positive current terminal of the relay/meter.
• The 'OUT-' is to be connected to the negative current terminal of the relay/meter.
Power Supply
The RIK requires 24Vdc power to operate. The power supply requires a 100-240Vac (50/60Hz) input and outputs 24Vdc to power the
Integrator.
• Connect the input power supply that is between 100-240Vac to the 'L' and 'N' terminals of the power supply.
• Connect the V+ and V- of the power supply to the +24Vdc and GND terminals of the Integrator.

2.3 Conguration
The face of the integrator has a set of dip switches that are used to congure the current range for the current channel. When the dip switch
is in the up position, the dip switch is ON. When the dip switch is in the down position, the dip switch is OFF.
Congure the channel dip switch to output the desired range. For example, to measure current rated for 500A, the dip switches 1 through 5
must be congured to 'OFF', 'OFF', 'ON', 'OFF', 'OFF'. The table below outlines the position of the dip switches for the desired current ranges.
Table 1 - Current Ratio Table
12345
50:1A ON OFF OFF OFF OFF
200:1A OFF ON OFF OFF OFF
500:1A OFF OFF ON OFF OFF
2000:1A OFF OFF OFF ON OFF
5000:1A OFF OFF OFF OFF ON
2.4 Measurements
For each current range, the Integrator will be able to measure the current from 0.5% up to 2000% of the rated current. When the integrator
is congured to measure a current rated for 500A, it will measure the current from 2.5A to 10000A.
The table below provides all the ranges of current that can be measured for each range.

2000 10 to 40000 1A @ 2000A 20A @ 40kA 2000:1A
5000 25 to 100000 1A @ 5000A 20A @ 100kA 5000:1A
