Distribution transformer plays the important function of providing isolation between secondary and primary voltage and it also helps in stepping the voltage down to the level that could be safely used in home and offices.
It is not directly a power loss, but results in inferior voltage regulation causing the secondary voltage not to be directly proportional to the primary voltage, particularly under heavy load transformers are therefore normally designed to have very low leakage inductance
Young Engineer Berba instructed the company engineers to reverse the connections on the primary voltage side, after which all the voltages on the secondary side came out balanced.
The phase difference between primary voltage and secondary, homologous, is in the clock-hour figures of the vector group 6.
Heavy Electrical Complex (HEC), one of the industrial units of State Engineering Corporation, is engaged in the manufacturing of power transformers of different types (total annual capacity 3000 MVA) with primary voltage rating of 66 and 132 KV.
Each lamp was read at rated primary and [+ or -] 10 percent rated primary voltage for a total of72 readings per lamp type.
A switch on the back panel provides convenient selection of primary voltage.
From the two running tests we found that at high values of the primary voltage the current is deformed and at small values the current has a perfectly sinusoidal shape, the primary voltage is dephased by 180[degrees] before the primary current.
The system also displays the highest demand available based on the coil type and primary voltage.
A primary monitor IC can be connected to measure input voltage, detect primary-side OV/UV conditions and monitor the input fuses, using resistor dividers to reduce the primary voltage to a suitable level for the monitor IC.
0 [micro]A rms drive current, generated by primary voltage source signal P and an auxiliary (drive) transformer, passes through: coaxial cable on the High (H) side of the bridge to drive port Dr(H) at external "star" connector Y; QHR device ac1 (connected in quadruple-series between external stars Y and Z; coaxial cables between out ports Ot(H) and Ot(L) on the High and Low (L) sides of the bridge; reference resistor 12.
