Product description

This chapter contains an overview of the design and function of the product.

Operating concept

The monitoring system is operated by keys for parameterization and configu­ration on the front panel of the device. Alternatively, configuration is also
possible via the TAPCON®-trol visualization software.

The monitoring system is equipped with a key lock to prevent unintentional

operation. To activate or deactivate, press the and keys
simultaneously.

Manual mode

Manual mode is an additional safety feature of the monitoring system and
protects the parameters from being unintentionally changed.

The following activities cannot be performed until you have activated manual
mode:

▪ Acknowledging events

▪ Acknowledging maintenance

▪ Changing parameters

You can change the parameters regardless of manual mode via the visuali­zation software TAPCON®-trol.

To activate manual mode, proceed as follows:

► Press .

ð The relevant LED lights up.

Manual mode is activated. If no key on the monitoring system has been
pressed after more than 5 minutes, manual mode is automatically deactivat­ed.

Serial interface

The parameters for the device can be set using a PC. The COM 1 (RS232)
serial interface on the front panel is provided for this purpose. You can use
the connection cable supplied to establish a connection to your PC via the
RS232 or USB port (using the optional USB adapter).

TAPCON®-trol software is needed for parameterization via the serial inter­face. The software and the related operating instructions are contained on
the CD provided.

Mounting

This chapter describes how to correctly mount and connect the device. Note
the connection diagrams provided.

WARNING

Electric shock

Danger of death due to electrical voltage.

► De-energize device and system periphery and lock to prevent switching

back on again.

Installing and wiring temperature sensors

The following sections describe how to install and wire the temperature sen­sors for the diverter switch oil and the transformer oil.

Connecting temperature sensor for on-load tap-changer oil

A temperature sensor is mounted in the on-load tap-changer head cover in
each on-load tap-changer. You have to perform the wiring in accordance
with the connection diagram that came with the motor-drive unit. Please ob­serve the following:

Do not loop the temperature sensor connecting leads when laying because
this may cause voltage coupling and result in measurement errors.

To connect the temperature sensor for the on-load tap-changer oil, proceed
as follows:

1. Place the shielding of the sensor connecting lead on the grounding rails
in the motor-drive unit.

2. Connect the sensor connecting lead to the terminals in the motor-drive
unit as shown in the connection diagram.

3. Remove the temperature sensor cover on the on-load tap-changer head
cover.

4. Remove the shielding of the sensor connecting lead on the temperature
sensor.

5.

NOTICE! Do not place shielding in temperature sensor. Insulate tem-

perature sensor connecting leads using shrink tubing such that the
shielding is no longer exposed. If this is not done, current may flow via
the shielding and the device may be damaged.

6. NOTICE! Guide connecting leads into temperature sensor. Ensure that
the cable entry point is watertight. If not, the temperature sensor may be
damaged.

7. Wire sensor connecting lead in the temperature sensor as shown in the
connection diagram.

8. Close temperature sensor cover.

When you close the temperature sensor cover, make sure that the seal is
correctly positioned and that no connecting leads are wedged in.

9. Ground the temperature sensor housing on the on-load tap-changer us­ing the grounding cable.

The temperature sensor is connected. Please continue with the next section
to connect the transformer oil sensor.

Connecting temperature sensor for transformer oil

You have to perform the wiring in accordance with the connection diagram
that came with the motor-drive unit.

Do not loop the temperature sensor connecting leads when laying because
this may cause voltage coupling and result in measurement errors.

1. Open the transformer thermometer case.

2. Fill the thermometer case with oil until the heat conduction sensor is
completely immersed in oil.

3. Place the shielding of the sensor connecting lead on the grounding rails
in the motor-drive unit.

4. Connect the sensor connecting lead to the terminals in the motor-drive
unit as shown in the connection diagram.

5. Remove the temperature sensor cover.

6. Remove the shielding for the sensor connecting lead on the transformer
oil sensor.
