El estandar “sagrado”
La instalación eléctrica dentro de los hospitals esta regulada por el
estandar IEC 60364-7-710. Esta es una aplicacion, no un
estandar de producto.
Siendo que un estandar IEC es aceptado y aplicado en casi todo
el mundo, cada país puede tener el suyo propio lo que es una
traduccion local y puede implementarse con algunas desviaciones
de “menor Atencion”
A veces podría haber también guías técnicas que son
herramientas de apoyo, pero no son leyes, solo sugerencias!

Recintos médicos
Recintos utilizados para
propositos como diagnostico,
tratamiento, monitoreo y
cuidado de pacientes.
Los recintos Medicos son mas
riesgosos que los recintos
communes porque los
pacientes pueden estar bajo
tratamiento medico que puede
implicar el uso de partes vivas
de equipamiento electrico
Pasillos, entradas, salas de
espera no son consideradas
como recintos medicos,
incluso si están dentro de un

Protección
Introducción al Sistema IT
Sistema IT: Este sistema no tiene un punto de conexión directamente a tierra,
estando aterrizadas solo las masas de la instalación. En este sistema, la corriente
resultante de la falla fase-masa no debe tener intensidad suficiente para provocar
aparición de tensiones de contacto peligrosas.
Debido a la alta impedancia entre fases y tierra la corriente residual es muy baja
para hacer actuar a un diferencial. Pero si hay una fuga de otra fase en relación a
la tierra, ahí será considerado un corto circuito haciendo que el dispositivo de
protección actúe.

May 14, 2015 | Slide 32
Protección
Introducción al Sistema IT
Este sistema es utilizado en instalaciones donde la continuidad de
servicio es fundamental, como por ejemplo salas quirúrgicas de
hospitales. En este sistema el interruptor diferencial no se utiliza.

Protección
Transformador de Aislamiento IT Médico
El sistema IT-Médico se obtiene por un Transformador de
separación monofásico.
El transformador de Aislamiento garantiza que en caso de una
primera falla a tierra o incluso un corto circuito entre fase y tierra
el sistema continuará operando normalmente.

Por qué el sistema IT-M es la solución?
Proteccion en apaatos electrodomesticos
Usualmente en aplicaciones domesticas se utilizan dos metodos
de protección:
Doble aislacion
Desconexión de alimentación (MCBs, RCDs)
La desconexión de la alimentación previene daños a las personas,
pero las cargas no funcionan.

Equipamiento Hospitalario
Por qué el sistema IT-M es la solución?
Proteccion en salas quirúgicas
Las fallas son amenzas a la vida delos pacientes porque las
partes vivas son utilizadas durante las operaciones.
La continuidad operacional es mandatorio porque la seguridad del
paciente depende del equipamiento electrico destinado a
tratamientos vitales.
El disparo de un diferencial no permite la continuidad de servicio.
El Sistema IT-M es la unica solucion que entrega protección y
continuidad de servicio.

Sistema IT-M, requerimientos
An IT-M system, provided by the mean of an insulating transformer
for medical use, must supply all the devices belonging to patient
environment
Insulating transformer for medical use: it provides separation
between upstream and downstream circuits and supplies
loads inside the surgery room
Insulation monitoring device: it monitors when a first fault to
earth occurs
The IT system assure continuity of service: in case of first fault to
earth medical personnel is able to complete medical treatments
An insulation monitoring device is required in order to constantly
measure the insulation to earth and signaling when a fault to earth
occurs

Sistema IT-M. Cómo funciona
Veamos que pasa en condiciones normales…
TI are ungrounded
Loads and extraneous masses are earthed to equipotential
bonding. This way all masses have the same potential which is
given, thus there are no risks while touching two contuctive
elements at the same time
Loads are working correctly

May 14, 2015 | Slide 39
Equipamiento Hospitalario
Sistema IT-M. Cómo funciona
Let’s see what happens during first fault…
Having a very high leakage resistance IT-M system may be
considered as an open circuit in parallel to the system
capacitance.
There is no current flowing through PE because neutral is
insulated from ground, thus both loads are working
© ABB Group
May 14, 2015 | Slide 40
Equipamiento Hospitalario
Sistema IT-M. Cómo funciona
Let’s see what happens in case of second fault…
The fault is like a phase to phase short circuit
Current is flowing through PE so protection can not be assured.
Patients are exposed to risk of electrocution in the time frame the
overcurrent devices take to trip
MCB must disconnect the network.

Escogiendo el Dispositivo Diferencial
Tips
Some examples
are uninterruptible
power supplies
(UPS), personal
computers,
printers,
electromedical
equipment etc
Algunas cargas incorporan circuitos electrónicos que, en caso de
falla a tierra causa Corrientes con componente continua que
pueden comprometer la operacion normal de un diferencial tiupo
AC.
Es por esto que las salas del grupo 1 y grupo 2 están obligadas,
dependiendo del tipo de corriente de fuga el uso de diferenciales
tipo A, que también puede intervenir con Corrientes yulsantes de
fuga o diferenciales tipo B también capaces de intervenir en caso
de Corrientes pulsantes uniderecioneles y continuas de fuga.
En el caso de una UPS de tres fases es obligatorio utilizar
diferenciales tipo B.

La finalidad del Isoltester es monitorear la red de las salas
quirúrgicas y las salas de UTIs que en caso de alguna falla
tanto por Aislación, como por elevación de temperatura en
el transformador de separación, o incluso en caso de una
sobre corriente; señalizar al equipo médico y al equipo de
mantención (a través de una señal sonora y una señal
visual) , para que ambos puedan tomar las devidas
precauciones antes de que ocurra una segunda falla en la
red.
Estas señales son emitidas a través de un anunciador de
alarma (QSD), que en caso de Salas Quirugicas deben ser
utilizados un QSD dentro de la sala y otro en la Enfermeria
y en caso de sala UTIs la norma exige solamente uno en la
Enfermeria.

signal into the IT-M network
V is the voltage
applied in direct
current
I is the measured
signal
The direct current signal overlaps
with the sinus value of the
alternated current, without changing
the electrical parameters of the IT-M
network
Measuring constantly the direct

Detección de falla
Procedimiento de prueba de rutina
Una fuga a tierra es detectada por el monitor de aislación
ISOLTESTER
La deteccion de falla es activada por medio de un botón en el
teclado del dispositivo. Esto ayuda a prevenir el funcionamiento no
intencionado.
El relé logico hace que todas las lineas de alimentación sean
abiertas por medio del mando motor instalado en cada MCB
S200.
El relé logico hace que cada mando motor reconecte uno por uno.
Luego de la operacion de reconexión el ISOLTESTER mide el
nivel de aislacion.
Tan pronto como la linea de falla se reconecta, ISOLTESTER
detecta la fuga a tierra.
La informacion de la falla de la linea es llevado al al relé logico por
medio de los relés de salida del dispositivo de monitereo de
aislacion.
Finalmente el display grafico indica que la linea de falla tiene que
ser mantenida.

Fault detection
Operational continuity it’s a key issue in operating theatres.
If a ground fault happens, the surgeon is able to bring to an
end the medical treatments thanks to the continuity of
supply granted by the IT-M system; but when the surgery is
finished the fault has to be located and recovered as soon
as possible.
Operating theatres have nowadays more and more medical
equipments that are supplied by different feeder lines. In
case of fault thus, it’s not trival to locate quickly which line
out of the many is involved.
Thanks to ABB command devices it is possible to automate
a fault detection system without any specific infrastructure.
The fault detection routine test is managed by a logic relay
with graphic display which allows total customization
according to the specific needs of each environment

Inspections and maintenance
Procedure
Measurement of
the current in the
alarm circuit can
be carried out in
conditions of dead
short earth fault
by inserting the
milliammeter in
series with the
conductor that
connects the
device to the
equipotential
node and
connecting one of
the conductors of
the isolated circuit
directly to earth

Measurement of the current in the alarm circuit
Purpose of the test: the circuit does not exceed the value of 1 mA
d.c. even in the case of a malfunction
Instrument: milliammeter
Hospital equipment
Inspections and maintenance
Procedure
After
disconnecting the
loads, each
conductor of the
circuit is
connected - one
at a time - with
the equipotential
node using the
rheostat
Fault simulation is
implemented by
reducing the
resistance of the
rheostat to a
value R < 50 k .
This must cause
the optical and
acoustic alarm
system to trip.
By increasing R
up to values
higher than 50
, the alarm can
be deactivated
automatically.

Trip test
Purpose of the test: to check that the insulation monitoring device
is functioning correctly, in other words, that the alarm signal is
activated when the insulation resistance value drops below 50 k .
Instrument: rheostat.
Hospital equipment
Inspections and maintenance
Functional test of signaling systems
Purpose of the test: to check that the optical and acoustic alarm
systems are functioning.
The test is performed by assessing, by means of a visual
inspection, that the following prescriptions have been respected:
Presence of the signaling indicator light, lit up green, indicating
normal operation
Presence of the signaling indicator light, lit up yellow, which comes on
when the alarm device intervenes
Impossibility of switching off the yellow indicator light; it must switch
off only after the signaled fault has been eliminated
Presence of an acoustic signal that starts to function when the alarm
device is tripped; the signal must be audible in the rooms of the
department where medical personnel are expected to be present

Inspections and maintenance
Procedure
Earth leakage of
the secondary
winding is
measured with
the transformer
powered with no
load at the rated
voltage, with the
insulation
monitoring device
deactivated and
by connecting the
milliammeter
between the
equipotential
node and each
pole of the
transformer one
at a time
The earth leakage
on the casing is
measured on the
accessible metal
parts that are not
connected to
earth, and on the
insulating parts by
applying a metal
sheet on these

Measurement of the leakage currents of the TI
Purpose of the test: To check that the earth leakage current of the
secondary winding and the casing of the insulation transformer is
not higher than 0,5 mA
Instrument: milliammeter
Hospital equipment
Inspections and maintenance
Procedure
The terminals of
the instrument are
connected on one
side to the
equipotential
bonding bus bar
and on the other
to the conductive
part or extraneous
conductive part.
The pins must be
located both on
the equipotential
bonding bus bar
and on the
conductive part.
In the presence of
a subnode, the
measurement
must be
performed
between the
equipotential
bonding bus bar
and the
conductive part or
extraneous
conductive part

Measurement of the supplementary equipotential
connections
Purpose of the test: to check that each connection between the
equipotential node and the earth of the plug sockets, the earth
terminal of fixed user devices and any extraneous conductive part
has a resistance no higher than 0,2
Instrument: four terminal switchgear, with a no-load voltage
between 4 and 24 V a.c. or d.c. providing a current of at least 10 A

Identification of extraneous conductive parts
Purpose of the test: to assess whether a metal part is an
extraneous conductive part by measuring resistance to earth. It is
considered to be an extraneous conductive part if the resistance
value measured is less than 0,5 M in group 2 medical locations
Instrument: ohmmeter or appropriate tool equipped with a plug
socket to be inserted in a socket of the system and with a sensor
to be placed in contact with the possible extraneous conductive
part.
