SELF-PROTECTED TRANSFORMERS
Single-phase or three-phase transformers which have protection elements against
overloads, external short circuits in the low voltage network and surges. They also
have oil immersed fuses in the high voltage side to insulate them from the electrical
network in case of internal faults.
Available for single-phase applications in capacities ranging from 5 KVA through
167,5 KVA and for three-phase applications in capacities ranging from 15 KVA
through 500 KVA with secondary voltage of 220 V and capacities of up to 1000

The visual inspection is not enough to know what is the
general condition of the transformer, for this reason the
electrical tests are required as a complement to know the
condition of the solid insulation of the transformers, as
they inevitably will deteriorate over time and its condition
will show how much remaining lifetime has the equipment.

SPECIAL DEVELOPMENTS:
We have venture in the development of special developments or custom made
products such as:
Current Limiting Bobbins:
Used to limit the fault currents
to 3 KA, during 2 seconds in
medium voltage (rating
through 15 KV) lines, BIL 95
KV and current ratings of 50,
100, 150 and 400 A.
Anti-theft covers (MAGLOCK):
High technology and high reliability
covers with a specially designed
stainless steel lock which provides total
adjustment between the cover and the
manhole, and avoids movement.
To remove the lock is necessary a
special tool, with a unique code
assigned to each utility company.
MAGLOCK helps to protect the
infrastructure of the utility companies
against theft, vandalism and accidents;
Round Type MAGLOCK: Covers available in polypropylene, metal and
polyconcrete.
Rectangular Type MAGLOCK R-1: Covers available in polypropylene.

Advantages:
Dust and moisture resistant.
Do not require electricity.
Do not require civil works or locksmithing for its installation.
Avoid vibrations between the cover and the ground (Less noise pollution, higher
lifetime of the cover because the material supports less fatigue stresses).
Oil immersed combined measurement transformers:
Manufactured with high class accuracy for measurement (0,2% or 0,5%) and
Voltage rating through 15 KV.
It has a front enclosure to install the
energy meter, the terminal board and
the wireless modem (If a remote
measurement system is required).
Useful as measurement equipment for
medium voltage in single or threephase applications, by means of three
or two elements method (As required
by
the
client)
using
current
transformers (CT) and potential
transformers (PT).
Current transformer (CT) specifications: Capacities ranging from 2.5VA through
15VA and current ratings ranging from 50/5 A through 4000/5 A.

or absence of energy in the 13,2
KV transmission lines and
transmits the events via GPRS or
RADIO to a SCADA platform or a
WEB application.
Auto-transformers:
Equipment specially designed to raise the voltage in specific
situations where, by regulation, the voltage drops are high and
do not allow offering the required voltage to the user.
