Safety symbols:
The following symbols are located on different parts of the equipment and this manual:
Paragraphs marked with this symbol contain information which, if not properly
followed, may cause damage to equipment and / or installation.
Paragraphs marked with this symbol contain information which, if not properly
followed, may cause personal injury or even death.
General Safety instructions:
The installation and operation of the products described in this manual can be
made only by trained personnel who have expertise in substation protection,
automation and control.
Do not disassemble the test block or test plug. Correct installation of internal
parts is critical to warrant the isulation and avoid internal arcs.
The ARTECHE guarantee ceases when, without express authorization of
ARTECHE SMART GRID S.L, external personnel to ARTECHE SMART GRID
S.L. makes any changes or reparation in the product. There are not included
the failures by normal use out of the guarantee period, neither by inappropriate
use, carelessness or negligence of the user.

Chapter 2. Cautions
1º-. It’s absolutely necessary to connect the equipment to earth according with the information
defined on chapter 5.
It’s absolutely necessary to connect the equipment to earth according with the
information defined on chapter 5.
2º-. To guarantee the correct operation of the test plug and extend his useful life it is
recommended to clean the fingers periodically for possible metal deposition in the plastic zone
of disruption, which may bring on to a reduction of electrical rigidity and insulation.
3º-. In the case that the customer wanted to make a new dielectric verification , these were
carried out according to point 10.6.4.3.7 of the IEC60255-27 standard (2014), 75% of the value
of dielectric strength established.
4º-. The test blocks are electrical equipment. Therefore, wrong installation or wrong
connection can lead to malfunction or permanent equipment failure, therefore it is
recommended to follow the instructions listed below:
The assembly of the test block should be done with wires which are not
energized.
The test block must be connected rigidly to the ground.
Check that the secondary windings of the current transformers are grounded
through one of its terminals.
Check that the connections are correctly tightened and that the contact
surfaces are clean.
Check the correct polarity of the connections.
Check the correct external wiring. The secondary of the current transformers
must be wired to intensity terminals: A and B.

ATTENTION. All secondary of a current transformer that is not loaded should
be short-circuited; otherwise, the voltage between open circuit and secondary
terminals can reach dangerous levels, even to destroy the equipment.
Chapter 3. Main features
The ARTECHE saTECH test block allows testing the protection relay, safely and easily,
completely insulating the protection relay from the field elements and eliminating any risk to the
user.
The main features are the following:
14 circuits with different configuration (trigger, currents and voltages). This
configuration should be defined prior to the order, because afterwards this
configuration can’t be modified.
Safe for the user, the user will never have access to live parts during insertion or
extraction of the test plug.
Safe insertion sequence, (make before break). The trip circuits are opened in the
first place, avoiding undesired operation and later on, the voltage and current circuits
are opened, ensuring that transformer circuits are shorted before opening the current
circuits.
Safe extraction sequence, the defined extraction sequence assures to have
enough time to stabilizing the system. The first step connects the voltage and the
current circuits, later on, the user must act specifically on the test plug before being
able to extract it completely.
Unique test plug for different test block configuration for the same number of
circuits (14).
Installation Orientation, there are two options: vertical and horizontal, the user is
able to choose the installation orientation.

Chapter 4. Applicatión
saTECH TSB
The test block saTECH includes 14 circuits, which can be accessed by removing the front
cover. The front cover guarantees an IP50 and its removal allows access to the internal
circuitry to enable testing operations.
All of these circuits include a contact that is normally closed when the protection relay is in
service.
The circuits can be classified into: trigger, voltage or current.

On the back side of the test block the circuits are identified by numbers and the numbers
surrounded by a circle corresponding to field.
The circuits include a mechanism for ensuring the short current transformers before proceeding
to open the corresponding contact test block. Arteche offers the possibility to select from
various types of shorted, depending on the application. On the front side of the block, you can
see which of those circuits are shorted, apart from identification shown on labels frame. This
identification is visible even when the test plug is inserted.
The user will define what kind of circuit (trigger, voltage or current) wants in each position at the
moment of ordering the test block saTECH TSB-14-H/V. The user should specify also the type
of short circuit required according to the selection table on page 10 models.
During the insertion of the test plug the circuits are ready to be able to test the protection relay,
according to the following sequence:
1. Opening of the trip circuits and signal.
2. Shorting the circuits of the current transformers.
3. Open the circuit of voltage and current.
Once the test plug is inserted, the protection relay is ready for testing; it will not affect the rest
of the system, because it has been insulated.

The field elements are automatically insulated through shorting circuits and opening the voltage
circuits and tripping.
saTECH TSB-14-P-H/V
The test plug TSP-14-P-H/V includes a guides and a poka-yoke system, to make easier the
insertion into the test block in the proper position and ensuring the opening of all contacts, of
the same type simultaneously. Once the test plug is inserted, it can be locked to prevent
involuntary extractions, turning the black buttons of the test block.
There are 28 banana plugs in the test plug, which allow the use of safety banana plugs: 14
banana plugs of 4mm are used for the test injection of the relay protection, and the other 14 to
provide access to field elements.
All the banana plugs of the test plug are identified by a number that corresponds to the same
number in the test block.
When the test plug is inserted into the test block, the user should push it until there is no gap
between the test block and the test plug, in order to guarantee that the retention system is
working during the safety extraction operation. To verify this, two lines have been arranged in
