I am having difficulty in understanding the curve settings of the above relay. I no longer have an image of this relay to understand the settings in the block.If somebody could post an image of the front panel aswell will appreciate it.
Hi guys
Can somebody help me with cable calc.
Our company tends to use the Amtech software which I'm trained in but it does not help with any HV cable calcs. I need a formula for this. The voltages that we use are generally 6.6,11,33 and 132kv.
So a common formula would help alot.
Thanks
how do you calculate the voltage drop on an hv cable, as we use the Amtech software to find the correct cable required for LV, there is no facility on the software to calculate the voltage drop in a HV cable.
Hi Guys
Can somebody please advise me as to what voltage can a SGB 33/6.6 kv transformer be tested at during a pressure test?
I would normally test any 33kv transformer at abt 15kv dc between phase and earth as it will be working voltage, but phase to phase i'm not sure abt. I'm using a T&R...
Guys, I would like to know if a Solkor relay can be used for transformer protection. I understand that the Solkor relay is used for zone protection but I came across 4 transformer feeders today that have Solkor relays connected to it. Thanks.
