NAME

Medium Voltage Laboratory

DESCRIPTION

This is a Medium Voltage laboratory that has two independent test spaces, each with a useful test development area of over 50 m2 and an independent control office to have visual contact with the test area to avoid any risk to people.
Laboratory capacities:
-Direct connection to the 30 kV distribution network
-Development of 4 MVA with (1) 15 Vac levels between 690 V and 4780 V, and (2) Vdc between 930 V and 6450 V.
-2MVA and 3MVA VRT generators.
-2MVA motor and drive converter.

MOST OUTSTANDING EQUIPMENT AND COMPONENTS

690 Vac VRT generators between 2 MVA and 3 MVA +

LVRT capacity up to 0 pu of 2 MVA and HVRT capacity up to 1.5 pu of 3 MVA

A drive motor with power converter to regulate the driving torque +

2 MVA power motor to regulate the driving torque

Electromechanical protection and switching systems +

Three cells (600 A/30 kV) in SF6, three ac switches (one 1200 A/12 kV in SF6 and two 1200 A/ 690 V), eight contactors (five 600 A/4000 V and three 200 A/4000 V)

Several ABB dry transformers +

Dyn11 of powers between 1 MVA and 2.6 MVA at 30 kV/690 V

Two Alkargo silicone transformers +

2 MVA 30 kV/2x690 V open D-secondary (two independent open D-secondary windings at the secondary). Together with a busbar cabinet, they are used to generate the 15 voltage levels mentioned in the description.
