How to calculate current transformers by load power?
Hello, I have 250 kW, can I use the 4 * 150 sip, the input av 400, and which CTs do I need to connect to the electricity meter?
Hello! With such knowledge and questions, I recommend contacting an electrician. Well, on the issues:
- Will there be a 4 * 150 SIP cable from VLEP? Is grounding already at the facility? This section is enough.
- AB 400 - yes, it is also possible, according to current it is power up to 262 kW.
- TT - I don’t know which, what meter, what maximum current is it designed for? Rather, this: nominal primary current ITT - 400 Amps; rated secondary current of ITT - 5 Amps; transformation ratio - 80.
