CAPACITIVE LOAD Description and Specifications for Lab Tenders
CAPACITIVE LOAD
It must consist of a single or three-phase capacitive step-variable
load. Housed in a metallic box.
MECHANICAL FEATURES
The load shall be composed of a rugged metal
structure and on the front panel all the controls, the protections, theoutput
terminals and a clear synoptic diagram shall be collected. This item must be
provided also with fuses protection.
ELECTRICAL FEATURES
The load shall be composed of capacitors, with possibility of star,
delta and parallel connection, controlled by three switches.
As a function of the switch position, there shall be the following phase
values (at 50Hz):
Position Capacitance Max power per phase
1 2 uF 30 VAR
2 3 uF 45 VAR
3 5 uF 76 VAR
4 8 uF 121 VAR
5 10 uF 152 VAR
6 13 uF 197 VAR
7 18 uF 275 VAR
Max reactive power in single-phase or three-phase connection 825 VAr.
Rated voltage in star
connection must be 380V, in D connection must be 220V, in single-phase must be
220V. 4 mm. safety terminal included on the front panel for the electrical
connection..
