Research of TVR electromagnetic field

Thyristor voltage regulator (TVR) is a 6 kV electrical installation which is being developed by NNSTU. The article is devoted to the study of the electromagnetic field (EMF), created by the TVR operation. The features and the principle of the TVR operation are described. The techniques for estimating the intensity of EMF exposure, developed by the authors, are presented. The dependences of the electric and magnetic field strengths on the voltage and the power of TVR for various calculation points have been obtained. It has been established that the intensity indices of EMF exposure do not exceed permissible norms, and the operation of TTR will not produce a negative impact on the personnel and on the secondary control and protection circuits. The results of the studies will be taken into consideration when choosing a rational arrangement of TVR elements.
