Abstract

Inventia se refera la un dispozitiv pentru com pensarea electronica, automata a erorilor transformatoarelor de curent. Dispozitivul de compensare automata a erorilor transformatoarelor de curent, conform inventiei, utilizeaza un amlificator electronic de putere mica, asociat cu un transformator de curent auxiliar care furnizeata integral puterea sarcinii, el poate fi aplucat tuturor transformatoarelor de curent, fara modificari constructive, deoarece semnalul de intrare al amplificarorului este preluat direct de la bornele înfasurarii secundare a transformatorului ale carui erori sînt compensate automat, iar iesirea amplificatorului este conectata direct la bornele înfasurarii secundare a transformatorului auxiliar.The invention relates to a device for automatic, electronic fault compensation of transformers. The automatic transformer error compensation device according to the invention uses a small power amplifier associated with an auxiliary current transformer which provides the full load power, it can be applied to all current transformers without any constructive modifications, since the signal of the input of the amplifier is taken directly from the transformer secondary termination terminals whose errors are automatically compensated, and the output of the amplifier is directly connected to the secondary auxiliary transformer terminals.
