Description
The windings are impregnated by vacuum VPI technology, so the transformer is dry, without oil, and can be installed inside a building. The Imprego Standard series covers isolating and single-phase transformers at 400/400 V, as well as autotransformers. The 400/231 V version reduces the line voltage of 400 V to the phase voltage of 231 V. For networks with non-linear load and harmonic distortion there is a version that takes the K-factor into account. The Imprego Medigo series is intended for medical rooms. The standard stock covers three-phase transformers of 8–400 kVA, and the whole range reaches 1250 kVA. Single-phase versions are also part of the program.
How to choose
First determine the type. An isolating transformer of 400/400 V is needed where the consumer must be separated from the network, and an autotransformer of 400/231 V where it is enough to change the voltage level. For hospital rooms, Imprego Medigo is taken, and for networks with harmonics the K-factor version. For power, use the three-phase 8–400 kVA from stock as a guide, and clarify larger ratings up to 1250 kVA in the inquiry.
