| <WRAP half column> Look at the indirect power measuring transformer (1 transformer connected to each phase) and find a ratio (e.g. 150A/5A). Use the result of this ratio (30 in this example) in the formula (10 000/30). Fill in the whole formula (i.e. 10000/30) into relevant box in SM2-RM menu [[..:..:web_zarizeni:vstupy_a_mereni|Inputs & Meters]].\\ | <WRAP half column> Look at the indirect power measuring transformer (1 transformer connected to each phase) and find a ratio (e.g. 150A/5A).
