Final answer:
A meter multiplier is a ratio used to convert electrical measurements from PTs and CTs. To find the meter multiplier, divide the number on the PT or CT nameplate by a specific value.
Step-by-step explanation:
A meter multiplier, also known as a transformer ratio, is a ratio used to convert electrical measurements obtained from potential transformers (PTs) and current transformers (CTs) into actual voltage and current values. To find the meter multiplier for a PT, divide the number on the PT nameplate by 120. In the given example, the PT has a meter multiplier of 20. For a CT, divide the number on the CT nameplate by 5. In the given example, the CT has a meter multiplier of 20.
