Brand: EDIBON | Category: Scientific & Laboratory Equipment

Shows what voltage transformers do in a protection scheme and which parameters govern the choice of a suitable unit. Students wire the transformer to the protection devices and measure the secondary quantities under different primary conditions.

A protection relay application reproducing the arrangement used in real electrical substations. Students set the relay characteristics, apply test quantities and observe the tripping behaviour, gaining experience with substation protection practice.
A high voltage laboratory built from a base unit and optional test kits for AC, DC and impulse voltage testing. The kits supply the test transformer, connecting bars, electrode sets and measuring capacitors needed to assemble each test configuration.
Shows the functions of current transformers in protection schemes and the parameters that decide which unit is suitable. Students connect the transformer to protection devices and measure the secondary current against the primary quantity.
