The sensors should be mounted in dry, indoor conditions without excess ingress of dust and corrosive gases. The sensors shall be protected against unusually heavy deposits of dust or similar pollution, as well as against direct sunshine.

The sensors are designed for standard ambient temperature between -25°C and +80°C (storage and transportation temperature between -40°C and +80°C). The altitude for mounting should be lower than 1000 m above sea level. The sensors may also be used at higher altitudes when agreed upon with the manufacturer.

For sensor dimensions see dimension drawings at the end of these instructions. Interface of KEVA

24 C10(c) sensor (dimensions of sensor cone) is compatible with CENELEC EN 50180 & 50181 type

Safety instruction

Always ground the sensor grounding terminal.

Installation conditions

The sensor should be installed in dry, indoor conditions. The temperature during the assembly shall be between 0 and +40°C. The sensor cable shall not be moved or bent if the temperature is below 0°C.

Mechanical installation

The sensors can be mounted into the multiple types of cable connectors according to the used type according Tab. 1. The mounting position for voltage sensor is shown in Fig. 5. The sensor is screwed into the cable connectors. Proper mounting is ensured by the tightening hex nut of size 24 mm which is part of the grounding cover (recommended tightening torque.

—

06

Before mounting of sensor remove dust from the surface of sensor using a paper towel. Then a mounting grease (Nexans-Euromold: Novagard

G687 or PE 1352 WT; or any other recommended by producers of cable connectors) must be used on the contact surface between the sensor and the cable connector to avoid the formation of air bubbles. The mounting grease contributes in making interfaces watertight and easy to install, see Fig. 6. Use a brush or a glove for lightly lubricating of the mounting grease.

Secondary cable, secondary connections

The secondary cable is a special shielded cable designed to give maximum EMI shielding. The secondary cable is inseparable part of each sensor and cannot be additionally extended, shortened, branched, modified, withdrawn or changed due to the guarantee of accuracy and performance of the sensor.

The cable shall be connected directly (or via a connector adapter if needed - for more information about connector adapters and coupling adapter refer to Doc. No. 1VLC000710 - Sensor Accessories.) to Intelligent Electronic Device (e.g. protection relay). The electrical shielding of cable is connected to connector shielding and shall be earthed on IED side. The cable shall be fixed close to metal wall or inserted inside of metal cable tray far from power cables! The minimal bending radius for the secondary cable is 35 mm. The cable cannot to be moved if the temperature is below

0°C. If cable, connector or connector grommet is damaged please contact the manufacturer for instructions.

Connection to the IED

The sensor cable is terminated by shielded RJ45 plug connector that shall be connected to the inputs of the IED.

See Appendix 1. in case IED is not complying with the same input impedance as defined by IEC

61869-11 standard (2 MOhm / 50 pF).

—

12

Note: It is recommended to use a cable tie to fasten long sensor cables approximately 10 cm from the RJ45 socket.

The sensor plug connector pin’s assignment is shown on Fig. 11. (Front view).

Voltage

Sensor wires connected acc. following assignment:

PIN 7 - a

PIN 8 -

Other pins remain unused

A cable not connected to the IED can be left open or short-circuited without any harm for the sensor. Nevertheless it is a good safety practice to earth cables not connected to the IED.

RJ45 plug connector has 8 contacts and locking latch coupling. The sensor connector plug shall be inserted properly with the IED matting receptacle before completing the coupling with the bayonet lock. Take care and do not use excessive force to plug-in and plug-out these connectors.

The used RJ45-type connectors (EIA/TIA 568A

Standard) are screened and designed to guarantee low resistance shielding; they are particularly adapted to applications where electromagnetic compatibility (EMC) is important. The connectors are robust but it is necessary to be careful during their assembly – do not use force!

Grounding terminal

The sensor grounding terminal is located on the same side as the sensor secondary cable and shall be connected to the ground during the sensor operation. To ground the sensor the grounding wire

(length 0,5 m) with the cable eye M8 is used.

5. Instructions for maintenance

Excessive dust or other kinds of pollution must be brushed off the sensor. Polluted sensors can be cleaned with spirit or petrol. Otherwise, during normal use the sensors do not need any additional maintenance.

6. Transport and storage

—

14

4. Instructions for use

The permissible transport and storage temperature for sensors is -40°C...+80°C. During transport and storage the sensors shall be protected against direct sunshine. The sensors are delivered packed into paper boxes or transport pallets. The conical surface must be protected against damage.

7. Recommended procedure for disposal of the sensor

The voltage sensors are used:

• To convert large voltages in the primary circuit of the network to the appropriate signal for the secondary equipment (e.g. IEDs);

• To insulate primary and secondary circuits from each other;

• To protect secondary equipments from harmful effects or large voltages during abnormal situations in the network.

The sensor does not contain environmentally hazardous materials. For disposal of the product after it has been taken out of use, local regulations, if there are any, should be followed.

The use of a sensor for other purposes than those described above is forbidden.

Routine test report

The routine test report includes following tests: a) Verification of terminal marking; b) Power-frequency withstand test on primary voltage terminal; c) Partial discharge measurement; d) Test for accuracy.

Correction factors are measured separately for each sensor during routine testing and are marked on the rating plate. The use of correction factors is required condition in order to achieve the declared accuracy class.

Appendix 1.

Offset factor

If the voltage sensors designed according to IEC 61869-11 standard are used with IED which is not complying with the same input impedance as defined by IEC 61869-11 standard (2 MOhm / 50 pF), the “Off set factor” shall be used to compensate input impedance matching error. The final amplitude correction factor („Adjusted CF

U

“) shall be then set to IED and shall be calculated in the following way.

Example:

1.0017

X = Adjusted CF

U

CF

U x

1,0017 x

Offset factor = Adjusted CF

U

0,99671 = 0,99840

Where:

• CF

U

is an amplitude correction factor mentioned on sensor nameplate or in Routine test report

• Offset factor is an unique factor for each IED type calculated to compensate impedance matching error between Sensor rated burden (2 MOhm / 50 pF) and IED input impedance – see the table below for IEDs

• Adjusted CF

U

is a final amplitude correction factor which shall be set to IED
