EDP V: Transformers

Transformers

Product Details


Introduction to Transformers

The LN training system EDP V provides practice-oriented measurements and fault finding in the area of transformers. The main components here are the three single-phase transformers (500VA). Measurements are conducted in various vector groups (star, delta) with respect to the neutral point (floating, direct or via a neutral earthing coil), under normal loading conditions and for faulty connections. Also included is a three-phase experiment transformer which is used to assemble various forms of single and three-phase networks. By combining both types of transformers parallel circuits of single- and three-phase transformers can be examined. Scott transformers and a Kuebler circuit can also be examined with this LN training system. Loads for the transformers are in the form of resistive, inductive and capacitive loads, each selectable in 14 stages for simulating various operating conditions both in single- and three-phase operation. The loads are designed so that they are suitable for generator exercises up to a rating of 1 kW. The system is part of the modular LN product group, "Electrical Power Engineering" and can be extended by the addition of other modular components (e.g. digital protection relays for transformers).
