Using Potential Transformers – Continental Control Systems, LLC - Ccs elements the wattnode meter rated as much as 600 vac and present day transformers rated to be used on circuits as much as 600 vac. Ccs does not supply capacity transformers, fuses, or cts rated to be used on medium voltage circuits, so you will need to discover different suppliers for these components. In this internet site we advise many pictures approximately modern-day transformer wiring diagram that we have accumulated from diverse websites from many image suggestion, and of direction what we advise is the maximum remarkable of picture for wiring diagram for four 20ma modern transformer . If you like the photograph on our internet site, please do now not hesitate to visit again and get inspiration from all of the houses inside the image of our internet image. Continental manage structures does now not promote cts rated to be used over six hundred vac, so ratio cts rated for 5 kv or better ought to be used. Those cts output five amps at their full scale rated cutting-edge. For instance, the secondary winding of a 500:5 ratio cts will output five amps whilst 500 amps flows through the ct’s primary, which is the conductor being measured. The 5 amp output of the ratio ct is then measured the use of one among our cts which will convert the five amp ratio ct’s output to a zero.333 vac signal:. If you are the usage of a wattnode® for lonworks® meter, we offer choice pt, which adds a configuration assets ucptptratio which configures the ratio of the outside pt, allowing the meter to routinely scale the voltage, strength, and power readings. For other fashions, you may also use pts, however you'll want to scale the meter measurements by means of the pt ratio for accurate effects.
Wattnode meters are available in seven voltage tiers as much as 600 vac line-to-neutral. For carrier voltage above six hundred vac, capacity or voltage transformers (pts or vts) are used to step down the voltage to a decrease variety in an effort to paintings with a wattnode meter. Pts are most normally used for 2400/4160 vac or higher electric services, however also once in a while for 575-600 vac three-section 3-twine delta circuits. Adding capability transformers has the impact of reducing the measured line voltage through the pt ratio (allow’s say 35:1 for this case). So a voltage of 4200 vac will become 120 vac. Since the meter sees one hundred twenty vac, many of the measurements it reports can be low by using a issue of 35 unless they may be scaled up by using 35.
