Handling instructions
Every effort has been made to ensure that the TRCP models are as
robust as possible. To achieve such an extremely thin Rogowski coil
the probe is necessarily delicate.
To prolong the life of the coil please observe the following handling
instructions.
The free end of the coil is unclipped in the direction shown. While the
illustration below is specifically related to the TRCP0300, Similar
handling instructions apply for the TRCP0600 and TRCP3000.
6 TRCP0300, TRCP0600, TRCP3000 User Manual
Tektronix Rogowski Current Probe
When clipping or unclipping the coil, hold the ferrule as shown in this
image.
WARNING. Never force the free end of the coil into the ferrule. This
could damage the coil insulation.
WARNING. Do not apply force to the cable attached to the coil. This
could damage the coil.
NOTE. When not in use, return the probe coil to the protective case it
was shipped in.
Safety and pre-use checks
WARNING. The transducer does not protect you from electric shock
while applying or removing the probe from hazardous live conductors.
Additional protective means are necessary to avoid electric shock from
hazardous live conductors which cannot be de-energized.
If hazardous live voltages are present and accessible in the
installation, appropriate protective equipment must be used.
WARNING. The Rogowski coil must not be used if the coil outer layer is
damaged or in any way compromised.
TRCP0300, TRCP0600, TRCP3000 User Manual 7
Tektronix Rogowski Current Probe
WARNING. The probe must only be used in conjunction with properly
grounded test equipment.
If the probe is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
The Rogowski coil
WARNING. The integrity of the insulation around the Rogowski coil
itself must be visually inspected before use, and the probe must not be
used if there are signs of damage.
WARNING. When bending the flexible coil around a conductor, avoid
tight bends and sharp edges that could damage the coil.
WARNING. The voltage rating (safe PEAK working voltage) is clearly
labeled on the cable adjacent to the coil. For the TRCP0300,
TRCP0600, and TRCP3000, see the coil insulation and voltage rating
in Specifications. Never use at voltages greater than this value.
WARNING. Voltage ratings are only valid if the free-end of the coil is
fully inserted into the socket, and remains fully inserted during use.
The coil has a friction fit, the coil is fully inserted when you feel that
you can ease the free end of the coil into the ferrule no further.
WARNING. The voltage ratings are appropriate for intermittent use of
the probe as a test instrument and not for continuous use in a
permanent installation.
For permanent installation the coil should be situated such that
corona, which will eventually damage the coil insulation, cannot occur.
For information regarding permanent installation of TRCP models on
high voltage equipment, please consult Tektronix.

The integrator
WARNING. The probe must only be used with oscilloscopes or
monitoring equipment that have their BNC inputs properly grounded.
Power options
The probe can be powered by an external DC source or by a battery
option.
External supply
The probe can be powered by an external DC supply. The DC voltage
must be 12 V (±10%) using a center positive connector. When the DC
supply is present a RED indicating LED adjacent to the socket is
illuminated.
Standard alkaline batteries
Healthy batteries are indicated by the Green Status Indicator LED. If
the LED is Red, the batteries are delivering less than 2V and must be
replaced.
When the DC voltage is present the batteries are inoperative.

Using your Rogowski Probe
Replacing the battery
Low battery is indicated by a red LED located near the power switch.
To replace the battery, remove the probe from the test circuit, switchoff the transducer, remove the battery cover, and replace the used
batteries with appropriate batteries for your transducer type (standard
or rechargeable).
Make sure the probe is removed from the test circuit before replacing
the batteries.
Switching on
CAUTION. Make sure you've read the following sections before
switching on the transducer: Safety and pre-use checks on page 7 and
Handling instructions on page 6.
WARNING. The probe may be used only with oscilloscopes or
monitoring equipment with properly grounded BNC inputs.
1. Connect the BNC output of the transducer to your grounded
oscilloscope or current monitoring equipment.
2. Visually inspect the Rogowski coil ensuring that the insulation is
intact. If you see an abrasion or tear, use a different probe.
3. If the coil passes the inspection in the previous step, un-clip the
coil and wrap it around the de-energized conductor under test.
4. Insert the free-end of the coil fully inside the ferrule.
5. Re-energize the conductor.
6. Use the Power button to switch the transducer On by pressing and
releasing the button. Turn the transducer Off by pressing and
releasing the button when the transducer is on. The transducer is
on when the Status Indicator LED is Green.
TRCP0300, TRCP0600, TRCP3000 User Manual 11
Using your Rogowski Probe
After using this procedure, the transducer may require a settling period
of up to 2 minutes before providing a correct current measurement. The
settling period is dependent on warm-up time and the low frequency
bandwidth.
Obtaining the best measurement
The Rogowski coil should be positioned so that the conductor under
test is encircled by the coil but is not adjacent to the cable attachment
(see picture below). The diagram shows the direction a positive current
should pass through the coil loop in order to obtain a positive output
voltage. The Rowgowski Current probe has been calibrated with the
conductor near the center (position A), and this is the ideal position for
accuracy.
For the best high frequency performance the center of the current
should lie on the line shown A to B, where B is half way around the
circumference of the coil.
Sensitivity to external currents and voltages
The sensitivity of the TRCP to currents that are outside the closed loop
of the Rogowski coil is very small, provided that the external currents
are less than the current rating of the probe or that such currents are
relatively distant from the coil. In the vicinity of a multi-turn conductor
the effects are far stronger than from a single conductor carrying the
same current, and such positions should be avoided.
If there is a surface with a high voltage very close to the coil and the
voltage is subject to high rates of change (e.g. 1kV/µs) or high
frequency oscillations in the MHz range, then measurement error can
arise due to capacitive coupling to the coil.
12 TRCP0300, TRCP0600, TRCP3000 User Manual
Using your Rogowski Probe
To check for any unwanted response to adjacent fields, it is
recommended to quantify the output of the probe when close to (but
not encircling) the conductor under test. This will reveal the magnitude
of any unwanted responses to currents close to, but outside, the coil.
Output cables
Your probe includes a 500 mm BNC to BNC output. It is possible to
use longer cables; these should be 50 ohm, single screened co-axial
cable.
Extension cables can be used if necessary. Consideration should be
given to routing very long extension cables.
Cleaning and decontamination
To prevent surface contamination the Rogowski coil and cable should
be inspected regularly.
To clean the coil and cable use a mild detergent and water to remove
any contamination, wipe with clean water to remove the detergent and
dry thoroughly with a clean cloth. The probe must be disconnected
from any external circuit and turned off prior to cleaning.
Returning your probe for recalibration or repair
To return your product for repair or recalibration, please contact
Tektronix in advance for shipping instructions (refer to Contacting
Tektronix for contact details).
