Hi Guys,
Can anybody help me with the Thermostat and Hygrostat setting calculation and recomendations . One of our end clients wnat us to submit the setting calcuation for Thermostat and Hygrostat for Protection cubicles.
Note: This is for middle eastern Region.
Thanks,
Hi,
While using Interposing Current Transformer , should we have to check the adequacy like that of Main Current Transformer
Ex: Main CT is 600/1A, Class: PX, Vk: 300V and Imag : 30mA @ Vk
If 300V is suitable for the Requirement wrt Main CT.
Interposing CT is 600/1/1A , Should...
Hi,
Can anyone suggest Two Phase Under Voltage relay? I am looking for a auxilary relay which can be mounted on DIN Rail and I have only Two Phase(R and Y) of VT as input.
Thanking you in advance.

Hi All,
In Hi-Z diff Protn we calculate Vpeak and if its greater than the Impulse Voltage rating of the TRM we go for Non-linear Resistor.
I wanted to the physics behind , How High voltage is generated in Hi-Z differential Protection during internal faults? Can anyone explain...
Hi,
This is wrt Hi-Z REF Protection.
The Phase CTs and Neutral CT parameters are same except the Rct Value. On Phase CTs the Rct(Ph) = 5 Ohm, On Neutral CT Rct(N) = 4 Ohm.
As the Rct Values are different there would be a Spill Current as the Dynamics are not Balanced.
