Safety instruction

All activities for installation, commissioning and maintenance

of this current transformer must be performed by qualiﬁed

personnel that have the knowledge of applicable safety

precautions. This guide assumes that the reader of this

document has suﬃcient electro-technical knowledge to

understand the content of this document.

General

The split-core is a current transformer (CT) and can only SC

be used for measuring electrical alternating currents. The SC

is suitable only for mounting on insulated primary conductors

in a weather protected and dry location.

Explanation of symbols

This product is designed according to the

EN-IEC 61010-2-032:2012 standards and therefore

this product meets the requirements of the Low

Voltage Directive 2006/95/EC.

Do not apply around or remove from UNINSULATED

HAZARDOUS LIVE conductors, which may render

electric shock, electric burn, or arc ﬂash.

Read the installation guide before mounting the

product. Unprofessional work activities on electrical

installations may result in a threat of danger to the life

and health of human beings and livestock!

Under no circumstances the secondary circuit of the

CT may be opened when the CT is closed and

current is ﬂowing in the primary circuit. High voltages

may appear on the secondary leads when this circuit

is left open.

RoHS Directive 2011/65/EU

GMC-I Messtechnik GmbH states that they only uses

qualiﬁed component in their products from

manufacturers, whose speciﬁcations meet or exceed

the requirements of the European Directive for the

Restriction of use of certain Hazardous Substances.

WEEE Directive 2012/19/EU

The 'crossed out wheeled bin' symbol indicates that

the equipment should not be disposed as unsorted

municipal waste. Contact a qualiﬁed recycler for

disposal.

Always avoid working on live parts of an installation.

Mounting instruction

No special tools are required to install a Current Transformer

( ) of the CT SC series. To connect the CT to the meter

correctly, please consult the installation guide of the meter.

Assembly

Under no circumstances the secondary circuit of the CT may

be opened when the CT is closed and current is ﬂowing in the

primary circuit. High voltages may appear on the secondary

leads when this circuit is left open.

1. Ensure a safe working area during assembly,

maintenance and inspection of the CT. If necessary,

disconnect the power of the primary circuit and make sure

it can not be enabled unintentionally.

2. Find the power direction of the cable you want to

measure. is recommended to mount P1 side to power It

source and P2 side to power consumer. If the CT is

installed like this, the arrow on the CT will indicate the

direction of the power ﬂow.

3. Open the CT and mount on the cable by using cable it

ties. Attention Do not close the CT. Otherwise high :

voltages may appear on the open secondary leads!

Attention

Do not touch the core surfaces by hand: skin acid may

damage the core. Avoid dust on the core surfaces.

4. Connect the secondary leads (S1 S2) to the low ,

impedance current input of the measurement instrument

(e.g., an ammeter or current input of kWh-meter).

5. Close the CT only when you are sure that the secondary

leads are connected to the current input of the

measurement instrument. The CT is properly closed when

you hear a ‘click’.

6. Enable the primary circuit if necessary.

7. Check if the is mounted and closed properly. CT

Check if the secondary leads are connected properly and

ﬁrmly.

Maintenance and inspection

 Check whether the secondary leads are connected ﬁrmly.

 Check whether the CT is closed properly.

 Check whether the CT is mounted ﬁrmly.

 Remove severe pollution on the casing. Contact with

moisture, especially with the core, must be avoided.

Attention

Do not touch the core surfaces by hand: skin acid may

damage the core.

Temporarily disconnecting the CT

The secondary leads of the CT always have to be connected

to a low impedance burden such as an ammeter. When

during maintenance, no burden is available to connect to, the

secondary leads of the CT (the two secondary terminals)

must be short-circuited.

Problem solving

e.g. unexpected values incorrectly values , reversed power, ,

 Check the settings of the meter by using the installation

guide of the meter.

 Check whether the CT is mounted on the intended cable in

the right direction.

 Check if the CT is closed properly.

 Check the value of the secondary burden (sec. leads length

/ diameter and meter impendent). See product/data sheet

for the max. burden value.

 If previous points did not solve the problem:

Check carefully whether there is dust or other pollution

present between the two parts of the core.

In case of pollution, the core surfaces can be cleaned with a

lint free cloth and then protected with an extremely thin

layer of acid free petroleum jelly (Vaseline).

Attention

Always follow the disassembly instructions when reversing

the CT.

Disassembly instruction

Tools are only required for removing the cable ties of the CT.

1. Ensure a safe working area during disassembling the CT.

If necessary, disconnect the power of the primary circuit

and make sure it can not be enabled unintentionally.

2. Open the CT.

3. Disconnect the secondary leads from the measurement

instrument.

4. Remove the cable ties. Pay attention not damage the

insulation of the primary conductor when removing the

cable ties. Remove the CT.

5. Enable the primary circuit if necessary.

Recycling

When the product has reached ‘end of life’, it must be

recycled. Do not dispose this product as unsorted municipal

waste. Contact a qualiﬁed recycler for disposal.
