Abstract
Using 1 kV as an intermediate voltage level in low voltage (LV) networks can be used to decrease the loop impedance and increase the power capability. 1kV systems are especially suitable when the voltage on existing cable can be raised from 0.4 kV to 1 kV. This is possible for most modern low voltage cables. This paper describes practical limitation and transformer parameters that can be specified when buying 1 kV transformers. The parameters have been optimized in cooperation with several transformer suppliers.
