Hello everyone,
Nowadays I am dealing with the following problem.
Assume an MV connection meshed grid with known configuration and technical characteristics, connecting many distributed generators through a unique "exit" at one bay of an MV/HV substation.
We are metering the energy produced...
Hello everyone
I have in stock 30kV/50MVAr reactors used for reactive power compensation and connected to the tertiary winding (30kV) of autotransformers (400kV/150kV/30kV T/F) of my transmission system.
Do you think that I could connect such a reactor to the tertiary winding (11kV) of a...
Where can I find specs and special requirements for designing an air-insulated transmission (say 50MVA) power substation situated at an altitude of 1000m (or more) above sea-level?
I need to estimate the reactive power generation of medium voltage (e.g. 20kV) underground cables at nominal-load and no-load.
Can anyone help by pointing to reliable technical info sources?
It seems that a high transformer (HV/MV)impedance protects the MV busbars from short-circuits in the HV Grid by limiting the short-circuit current.
Accordingly a high impedance value should be desirable in all cases.
What are the parameters influencing the increasing of a transformer's...
