INDUCTIVE LOAD Description and Specifications for Lab Tenders
It must consist of a single or three-phase inductive step-variable load.
Housed in a metallic box.
The load shall be composed of a rugged metal structure and of a front
On the front panel all the controls, the protections, the output
terminals and a clear synoptic diagram, shall be collected.
The load shall be composed of inductances, with possibility of star,
delta and parallel connection, controlled by threeswitches.
This item must be provided also with fuses protection.
As a function of the switch position there shall be the following phase
