Abstract (en)

[origin: EP1022749A1] An electrostatic capacitive divided-voltage transformer, basically includes: a conductor (2); an inner semiconductive layer (3); a main insulative layer (4); an outer semiconductive layer (5), the conductor being enclosed with the inner semiconductive layer, the main insulative layer, and the outer semiconductive layer in this sequence; a first metallic layer (6), the first metallic layer enclosing the outer semiconductive layer; an auxiliary insulative layer (7) arranged on the first metallic layer; and a second metallic layer (8) arranged on the auxiliary insulative layer, a divided voltage from a whole voltage between the conductor and the second metallic layer being enabled to be led between the first metallic layer and second metallic layer. The electrostatic capacitive divided-voltage transformer is applicable to a voltage detector together with a digital meter or digital relay. <IMAGE>
