The range includes up to 33 KV systems and as per the site requirements. A Earthing ( zigzag) transformer is a special purpose transformer with a zigzag or 'interconnected star' winding connection, such that each output is the vector sum of two phases offset by 120�. Its applications are for the creation of a missing neutral connection from an un-grounded, 3-phase system to permit the grounding of that neutral to an earth reference pointand also harmonic mitigation, as it can suppress triplet (3rd, 9th, 15th, 21st, etc.) harmonic currents, to supply 3-phase power as an autotransformer (serving as the primary and secondary with no isolated circuits), and to supply non-standard phase-shifted 3-phase power. Nine-winding three-phase transformers, typically have 3 primaries and six identical secondary windings which be used in zigzag winding connection as pictured. As with the conventional delta or wye winding configuration three-phase transformer, a standard stand-alone transformer containing only six windings on three cores can also be used in zigzag winding connection, such transformer sometimes being referred to as a zigzag bank. In all cases, six or nine winding, the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core. The second coils are then all tied together to form the neutral and the phases are connected to the primary coils. Each phase, therefore, couples with each other phase and the voltages cancel out. As such, there would be negligible current through the neutral point, which can be tied to ground. Each of the three "limbs" are split into two sections. The two halves of each limb have the equal number of turns and they're wound in opposite directions. With the neutral grounded, during a phase to ground short fault, a third of current returns to the fault current and the remainder must go through two of the three phases when used to derive a grounding point from a delta source. If one phase, or more, faults to earth, the voltage applied to each phase of the transformer is no longer in balance; fluxes in the windings no longer oppose. (Using symmetrical components, this is Ia0 = Ib0 = Ic0.) Zero sequence (earth fault) current exists between the transformer’s neutral to the faulting phase.The purpose of a zigzag transformer in this application is to provide a return path for earth faults on delta-connected systems. With negligible current in the neutral under normal conditions, providing the defective load will be automatically disconnected in a fault condition, an undersized transformer may be used only as short time rating is required (i.e. the transformer can only carry full rated current for, say, 60 s). Impedance should not be too low for desired maximum fault current. Impedance can be added after the secondaries are summed to limit maximum fault currents(the 3Io path).

It is a special – purpose transformer with a Zigzag or interconnected star winding connection, such each output is the vector sum of two phases offset by 120°.

We use superior quality material in the manufacturing of grounding transformers that help us in providing a product that is highly durable and resistive to corrosion. The delivery of these transformers is made with the stipulated time period.

We have gained expertise in delivering a quality range of Earthing Transformers with various capacities. The wide range of Earthing Transformers offered by our firm is well designed by experts in compliance with the international quality standards.   In cases where the neutral point of three phase system is not accessible like the system connected to the delta connected side of an electrical power transformer, an artificial neutral point may be created with help of a zigzag connected Earthing Transformer. This is a core type transformer with three limbs. Every phase winding in zigzag connection is divided into two equal halves. One half of which is wound on one limb and other half is wound on another limb of the core of transformer. End point of all three windings ultimately connected together and forms a common neutral point. Now if any fault occurs at any of the phases in delta connected system, the zero sequence fault current has close path of circulating through earth as shown in the figure. In normal condition of the system, the voltage across the winding of the Earthing Transformer is 1/V3 times of rated per phase voltage of the system. But when single line to ground fault occurs on any phase of the system, as shown in the figure, zero sequence component of the earth fault current flows in the earth and returns to the electrical power system by way of earth star point of the Earthing Transformer. It gets divided equally in all the three phases. Hence, as shown in the figure,    the currents in the two different halves of two windings in the same limb of the core flow in opposite directions.  And therefore the magnetic (lox set up by these two currents will oppose and neutralize each other. As there is no increase in flux due to fault current, there is no extra dcp/dt means no extra voltage induced across the winding   and no choking effect occurs to impede the tow of fault current. So it can be concluded like that, the zigzag type Earthing or grounding transformer maintains the rated supply voltage at normal current as well as when a solid   single line to ground fault current flows through it. The rated voltage of an Earthing or grounding transformer is the line to line voltage on which it is intended to be used. Current rating of this transformer is the maximum neutral current in Amperes that the transformer is designed to carry in fault condition for a specific time. Generally the time interval, for which transformer designed to carry the maximum fault current through it safely, is taken as 9 second.
