hello,
we have a substation equipped with multilin 1000 CCU from GE and an HMI with GE power software 5.8.0. we need to install an other HMI for remote operation. is it possible to export/ import the current settings of the existing HMI? we are thinking of VPN connection to the CCU.
cheers
hi everyone,
we are going to implement a temporray solution to connect three substations to a central location for control and monitoring. the substations are equipped with CCU GE multilin 1000. i am thinking to use GE D400 gateway and use the internet as a communication channel. do i need to...
hello,
we have a 36kV power transformer with on load tap changer, 36kV switch-gear. we have load on 40kms from the substation. shall we procure higher voltage cables rating (20.8/36 max 42kV instead of 18/30 max 36kV) to allow the tap-changer compensate the voltage drop? or we should use...
we are designing 4 X 33kV line of about 30km long. according to the Etap simulation, reactive power is generated in the line on light loads. it is considerable amount of mvars. how can i reduce this amount of reactive power?
cheers
hello everybody,
i am working on specifications for 33kV and 22kV grid. i want to specify the power factor correction capacitor banks. what is better for the internal connection of the capacitors? Delta or wye? Ive read that as per standard IEEE Std 1036-1992; Delta connected capacitors are...
hello,
we have HV/ MV power transformers. we've installed capacitors on the MV side of the transformer. is there any chance that the capacitor affect the HV side by increasing the voltage or its only affecting the MV side of the transformer?
regards,
hi all,
while I was looking to a single line diagram of a substation, I noticed the following line in the protection table:
( GE F650( O/C & L/R & W/R)). I've checked the datasheet of GE F650 but i couldn't find any kind of protection called L/R or W/R. and I don't think it is the decaying...
hello,
I am in the stage of taking over a 36KV switchgear feeding transmission lines. I've noticed that the model number of the CB from ABB is starting with HX/B-E.....the name plate is saying its an SF6 CB, but what i know that ABB has the HD4 CB. i searched google for that number but i find...
