Abstract
CIRCUITO PROTECTOR PARA VARISTORES DE OXIDO DE ZINC. EL VARISTOR (10) COLOCADO EN PARALELO CON EL CONDENSADOR (11) DE UNA LINEA DE TRANSMISION AL QUE PROTEGE, TIENE ACOPLADO UN TRANSFORMADOR DE INTENSIDAD (CT 14) DE FORMA QUE CUANDO LA ENERGIA QUE DISIPA EL VASTIDOR (10) ES EXCESIVA, EMPIEZA A CONDUCIR EL ELEMENTO DE RESISTENCIA VARIABLE (Z), DISPARANDO EL DISPOSITIVO DE ENTREHIERRO (12), QUE LLEVA UNA BOBINA (13) PARA LIMITAR LA CORRIENTE.
