WebOct 31, 2024 · The following steps will help when reading an electric meter: Take a pencil and paper out to the meter and stand in front of it, as close to eye level as possible. Draw five circles on the paper ... Another example with PTs and CTs.Say you have a 480v three phase three wire service with 200/5 CTs and 4/1 PTs. What is the watthour meter multiplier? 200 divided by 5 equals 40. 4 divided by 1 equals 4. So, 40 x 4 = 160. Thus, the watthour meter multiplier would be 160. When you divide out the CT ratio … See more CT’s and PT’sare used to step down current and voltage in a metering circuit to a safe and measurable level. But this leaves us with a little bit of math to do to … See more Let’s say for instance that you have a 120/208 three phase 4 wire wye service that is using 400/5 CTs. How would you determine the watthour meter multiplier? … See more So, there you have it. To calculate watthour meter multipliers first you need to determine whether there are CTs and PTsor only CTs in the circuit. Next, divide out … See more rose print bum bag

WebThere are a couple of ways to determine the resistance value of the multiplier. One way is to determine total circuit resistance using Ohm’s Law in the “total” column (R=E/I), then subtract the 500 Ω of the movement to arrive at the value for the multiplier: ... This is how practical electrical meters are designed and used: a sensitive ... WebJun 21, 2024 · The multiplication factor represents how much these current and voltage values have been scaled down. For instance, if your meter's current transformer scales down current readings by a factor of 10 and its voltage transformer scales down voltage readings by a factor of 4, your MF would be 10*4 = 40.
