ct pt connection diagram

This means that unlike self-contained services the customer’s power is not interrupted when the meter is removed. You will be better off if you meter each tenant separately. Why Does it Seem Like my Power Bill Keeps Going Up? The short answer is yes but I have sent you an email. Thanks a lot!. Enough about CT’s, let’s talk about PT’s.

Would it be 2 CT’s and 3 voltage connections or 3CT’s? Meter multipliers are used when meters are installed in transformer-rated installations. So I know that the CT ratio is 500:5 and it’s a 3 phase 4 wire supply 3 x 230/400V. If they found that the multiplier was incorrect and have now corrected it then yes your bill could double in this case. For example, some utilities require anything over 480v to be transformer-rated. Read why you should be using PT’s here. I know that I said before that you should consult with the engineer and you should but the formula that we use for current transformer sizing for a single phase transformer is:


However, you can still connect the meter with potential transformers. If ct ratio is 600/5 and meter ratio is /5. The transformation ratio of the current transformer is always remained high, whereas for the potential transformer its remains low. 9S Wiring Diagram (4 WIRE WYE) 3 PH, 4 WIRE (3 PT, 3 CT) GLEMS would like to thank and acknowledge the use of the following meter connection diagrams from Dr. Bill Hardy, TESCO.

This means that there is a hole in the middle to pass the wires through.

Thank you , for this great review . Typical ratios are 200:5, 400:5, 600:5, 800:5 and so on. You will need the measuring instruments having higher range, which literally mean huge instruments.


Close, it would actually be $2880. (adsbygoogle = window.adsbygoogle || []).push({});

In the above diagram i shown three ammeters current transformers, in the above CT wiring diagram i common a wire of all CT s, my means that i connect CT one connection with one another. (adsbygoogle = window.adsbygoogle || []).push({});

This section describes the most common service types and PT circuits encountered. Typical CTs for this application include: We call this technique piggybacking. For example, 4200 / 120 = 35. I have sent you an email with the details. amzn_assoc_enable_interest_ads = "true";
The utility might have a tariff requirement that they obtain an actual reading at least once a year or at least once every 12 months. Hey, I will need some more information from you. Hi, I have a customer who employs a old CT revenue meter and wants to have it upgraded, I know our local supply company supplies the revenue meter but the consumers wants to order a new enclosure with three CT’s etc, can you please recommend any NZ or Aussie suppliers.

This can actually be desirable depending on the rating factor of the CT. If there are any other questions that you may have please let me know.

The short answer is yes. Generally, current transformers are expressed in their primary to secondary current ratio.

You do not want to overdrive the meter by placing more than 20 amps in the meter base because you sized the CT’s incorrectly. I sent you an email. For example if a service has 200:5 CT’s and 2.4:1 PT’s, the multiplier will be 96. My running load is around 110 HP and my bill comes very high compared to other plants who have the similar machines. If your PT has a different secondary voltage, you will need to make sure the WattNode meter’s voltage rating matches the secondary voltage. However, the reported power, reactive power, and power factor for the two individual phases may appear imbalanced, even if the actual load is balanced, so in this configuration, only the power and energy sums are meaningful. Adding potential transformers has the effect of reducing the measured line voltage by the PT ratio (let’s say 35:1 for this example).
