Single-phase ultra-insulation transformer for galvanic separation of circuits or machinery, dry type, with electrostatic screen between primary and secondary. With a metal layer that offers a degree of protection IP23.

This ultra-isolation transformer provides separation between primary and secondary circuits through a safety electrostatic screen that filters and conducts unwanted signals and disturbances to ground. Referenced to ground it can generate neutral in two-phase installations. The degree of effectiveness of this screen depends directly on the quality of the installation's grounding. For the generation or referencing of the neutral it is necessary to ensure an efficient ground connection.

They are supplied in a metal box that provides an IP-23 insulation degree, connection through terminals. It does not incorporate any overload protection circuit.

Manufactured with low loss magnetic sheet providing high performance.

Question

Buenas tardes. Le explicó lo que tengo y lo que necesito a ver si me puede ayudar a saber cuál transformador me funcionaria mejor. En casa tengo línea 230v monofásico. Al testear: Neutro y fase me da 237v. Neutro y tierra 137v Fase y tierra 137v El cargador del coche eléctrico que es donde tengo el problema(Renault zoe) , no me funciona por la falta de neutro. El transformador sería solo para este cargador. Buscando en los foros he encontrado que el ZOE necesita que la instalación eléctrica sea de 230 Voltios entre fase y neutro (se afirma que si los 230 Voltios son entre fase y fase no funciona), que entre el conductor de tierra y el neutro la tensión no supere los 10 Voltios y que la resistencia de tierra no supere los 150 Ohmnios.

Answer

Buenos días.

Si usted tiene una instalación monofásica, cuando realiza las mediciones Neutro y fase 230 Vac, Neutro y Tierra 0 V o muy próximo a él, Fase y tierra 230 Vac.

Entre neutro y tierra no puede medir 137 V. la única posibilidad que se nos ocurre es que usted no tenga una instalación monofásica con neutro y fase, sino una instalación bifásica sin neutro pero con tierra, entocen al medir entre fases tiene 230 Vac, al medir entre Fase y tierra tiene 125 Vac aproximadamente.

Ebn una instalación para saber cuál es el neutro se mide con respecto a tierra, la medición entre neutro y tierra tiene que ser 0 V , como en una instalación tierra está claro cuál es, pues el otro cable será el neutro.

Si tiene dudas, lo mejor sería que contactase con un servicio profesional.

Una vez que tenga claro el tipo de instalación que tiene se puede analizar cuál sería el transformador que necesita.

Saludos
