I am not that much familiar with communication protocols. Can anyone suggest me some good reference so that I can study it from the Substation Communincation stand point.
Thanks in advance.
Do we traditionally install a Multifunction Protection Relay on a Low Voltage MCCB? Will it operate like a Power Circuit Breaker from a Protection Relay?
Thanks
I am working on a retrofit for 480 Cutler Hammer switchgear where the width of each section is 21". I have to install CTs and I need window type 3000/5A relaying CTs which can be placed side by side.Can anyone suggest me CTs with small dimensions and suitable window size (max. 3 inches) for such...
At how many times of rated current normally a metering CT saturates? I have a metering CT of 0.3B0.5, 600/5A class and want to use it with a protective relay which will pickup at 600A. Can I use this CT with the relay or I need a relaying class CT?
Thanks
While we carry the Arc Flash Analysis using SKM or ETAP, we will get the results for Incident energy, Arc Flash Boundry and PPE required for that particular switchgear. Now the results will depend upon Short Circuit and Coordination Studies.
The question I have is that now a days there are...
We are using GE Spectra Series 1600A, 380V, 3P+N+G busduct for one of our feeder. During insulation resistance tesing we found that the value of IR is in Giga-Ohms for phase to ground and phase to neutral. But for Neutral to Ground the value is in Megaohms (i.e. 400 Mega-Ohms) while for other...

We are replacing old CEE Relays with Digital Relay in one of our Project. I need the CEE Relay Manuals for the following models.
DTM 7031
ITV 7164
ITG 7201
HTG 7025
ITV 7166
I searched the internet but these models are not available, also no response from CEE to my email. Any help will be...
I have carried out the Relay Coordination for 13.8kV and 380V Electrical System. The Study has been submitted to the consultant. The Low Voltage Circuit Breaker are equipped with Electronic Trip Units. I did the Overcurrent coordination using my protective relays as we are not considering to use...
