Delta Metering Wiring Diagram

This configuration of voltage sources is characterized by a common connection point joining one side of each source.

Delta metering wiring diagram. Open delta transformer connection diagram let s pretend that while in service the b phase of a standard three phase delta transformer failed this is the winding located between the b and c connection. Wye delta voltages and line current phasor diagram. The gamma xl also has other interfaces for example can bus and wi fi connections. The only difference is that it is larger.

A delta connected relay doesn t see the wye voltages so we ll remove them in figure 6 9 which is a good representation of what the test set thinks is happening using delta voltages and wye currents. The drawings that i am using are from book 2 of the meterman s bible which we. Delta voltages and line current phasor diagram. The new solenoid driven metering pump gamma xl is the enhancement to our proven gamma x and covers a capacity range from 8 80 l h at 25 2 bar.

Be aware that these are general diagrams using standard test switches which may not match some utility standards in their configuration and are for reference only. This allows the gamma xl to network with all systems devices and platforms. Notice that we are going to be metering a single phase three wire service. The delta is a solenoid driven diaphragm metering pump.

One of the most requested items of information that we receive is for wiring diagrams for the meters we sell. It covers a feed range from 2 0 gph at 363 psi 8 l h at 25 bar to 20 gph at 29 psi 75 l h at 2 bar. Motors loads are commonly connected to phases a b and c while single phase loads are connected to either phase a or c and to neutral. Four wire delta circuits a four wire delta 4wd electrical service is a three phase delta service with a center tap on one of the transformer windings to create a neutral for single phase loads.

With and without ct s and pt s for wye delta and network circuits. Form 4s meter wiring diagram. Metergod monday session 16. Connectivity of the 5s 35s and 45s meter on 3 phase 4 wire and 3 phase 3 wire service.

For the form 4s meter wiring diagram let s start at the bottom. Due to its wide adjustment range both the stroke length and the stroke rate can be varied this output range is covered by seven different pump sizes. Initially we explored the idea of three phase power systems by connecting three voltage sources together in what is commonly known as the y or star configuration. We have two phase wires and a neutral.
