The main features of the line of blocks and plugs of 14 circuits in TSB SaTECH range are the
following:
14 circuits, versatile selection, with different configuration (trips, voltages and
currents, contact type 1, 2, A and B, with the alphabetical designating currents). 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, and any field connection is located on safety connectors.
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.
Avoid errors in the maneuver: Using the cover plugs available in the plug:, User
errors are avoided blocking access to field voltages and currents.. (plug odd
terminals in case of model 14, terminal pairs in the case of model 14RC) in type
contacts 2, A and B, and / or avoiding the injection of other power sources in type 1
contact. Cover plugs are compatible for all test plug terminals.
Type 1 contacts are referenced to circuits that open in the first phase (trips, signals and
protection power supply).
Type 2 contacts are referenced to circuits that open in the second phase (voltage).
Type A contacts correspond to the current circuits with automatic short-circuited.
Type B contacts are referenced to current circuits with automatic short-circuited, indicating the
end of the shot-circuit group.

installation.
Chapter 4. Principle of Operation
Test Block Cover
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. . This
construction guaranteed that you will never be in direct
contact with active parts of the system.
Type of circuits
In the test block there are different types of circuits,
they can be classified as trip, voltage, current or circuits
type contacts 1, 2, A and B respectively.

In the front of the block will be identified by two tag (upper and lower) and in the back will be
associated with the front by Labels with the same legend, where those that are within a circle
will correspond to the field part and those not to the relay part. As a mnemonic rule, the idea of
© circle Field can be used.
Closed Circuit
In normal state the test block circuits are closed contacts.
While the field terminals (identified by numbers inside
circles) connected to transformers and the equipment
(Protection) terminals connected to the equipment.
Open Circuit
The opening of circuits is achieved inserting the
test plug inside the test block. With this
maneuver the field and protection circuits are
pull apart.
Opening sequence (Test Plug Insertion)
During the insertion of the test plug the circuits are ready to be able to test the protection relay,
according to the next ordered sequence:
1. Opening of the trip circuits and signal.
2. Shorting current transformers circuits
3. Open voltage and current circuit.

Current Circuit
It is not required externally short-circuit of the
current transformers in the test plug. 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, also
from identification shown on labels frame. This identification is visible even when the test plug
is inserted.
Lock & Unlock Test Plug
Once the test plug is inserted, it can be locked to
prevent involuntary extractions, turning the black buttons
of the test block.
For test plug removal is necessary to unlock it, turning
the two buttons and unlocking the retention
mechanism.
Signal Injection
Once the Test Plug is fully inserted tests signal
injections can be performed with bananas by the
Test Plug. With Test Plug inserted the field
elements are automatically isolate, shorting
current transformers and opening voltage / trip
circuits.
Closing sequence (Test Plug Extraction)
The retention system force to do the extraction of the test plug, with the following sequence:

1. Connect current and voltage circuits
2. Open current transformers short circuit
3. Unlock Test Plug
4. Connect trigger circuits.
Stabilization system in the extraction
In the test plug extraction, before trip circuit
connection, it is necessary to stop and press the
two buttons to unlock the latching mechanism.
This operation will allow voltage and current values
to stabilize after transients during the connection,
and will avoid unwanted tripping during the trigger
circuit connection.
Guided and poka-yoke
The test plug includes a guides and a poka-yoke
system(Prevents improper connections), 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.
During test plug insertion and extraction there are not bounces that could
damage current transformers.

During test plug insertion and extraction maneuvers care should be taken to align and insert
properly the test plug in the block, one uniform movement should be done to avoid
misalignment between plug and block.
Reference lines
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
the plug. Once they are aligned with the framework of the block, they will help us to check
visually whether the plug is properly inserted or not.
Banana Connection
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.
In cases where a multiple plug banana connection in series is required, the

use of bent bananas is necessary to avoid the handle of the test plug. From our experience we
recommend using the security strap of the Stäubli Electrical Connectors Multi-Contact Right-
angle adapter XWA-4/19 Ref. 66.9694. Page 71.
Plug Covers
A set of plug plastic covers is supply with the test plug, which is
recommended to place in the plugs where you want to avoid banana
connections. These covers are compatible for all the plugs.
It is advisable to place covers on the circuits that are used for
protection supply, to avoid errors in the protection power supply.
These can be removed if in the protection a new power supply is
required.
These plug covers must be removed or put by qualified personnel.
