Simulator Of A Power Transmission Line Didactic Equipment Electrical Engineering Lab Equipment

Item No.: SEL-2
SEL-2 Simulator Of A Power Transmission Line Didactic Equipment Electrical Engineering Lab Equipment
Description
SEL-2 Simulator Of A Power Transmission Line Didactic Equipment Electrical Engineering Lab Equipment

The simulator reproduces a 130-km long power transmission line of 77 kV.
TECHNICAL CHARACTERISTICS:
• Desk-type box of chemically treated sheet steel, painted with epoxy coats.
• Side handles for easy transport.
• Fore panel of insulating material, with screen silk printed diagram of the components.
• All safety terminals ø 4 mm.
The simulator operates with Un: 3 x 220 V and it reproduces a 130-km long power transmission line of 77 kV, with the following characteristics:
• Rated voltage: 77 kV
• Rated current: 100 A
• Rated power: 13 MW
• Equivalent resistance: 3.5 Ω
• Concentrated equivalent capacitance: 10 µF
• Loop earth impedance: 0.8 Ω
The transmission line is protected against overload and short circuit by quick blow fuses.
COMPONENTS INSTALLED ON THE PANEL:
• Model of line: concentrated parameters, PI cell
• Simulated Un: 77 kV
• Operating Un: 3 x 220 V, 50 Hz
• Simulated Pn: MVA
• Simulated In: 100 A
• Operating In: 0.5 A
• Distributed equivalent R: 3 x 1.5 Ω or 3 x 23 Ω, selectable.
• Distributed equivalent L: 3 x 10 mH or 180 mH, selectable.
• Capacitors of line start and end: 3 x 2 µF or 3 x 0.22 µF, selectable. They may be connected in star, delta confi guration, or earthed.
• Earth loop impedance: 0.8 Ω selectable.
• Three-pole switch of connection of the line.
• Fuse-holder with fuses: 6 x 30 In: 1 A
Possibility of using the line separately, or more lines series/parallel connected.
Dimensions: 415 x 400 x 150 mm
