The normal life of a transformer is well above 25 years. The economical operation of the distribution system has its roots in the equipments being used. The economy being such, that it is financially advantageous to replace transformers with more than 15 years of service in the second perennial market. Testing of transformer is required, as its an indication of the extent to which a transformer can comply with the customers specified requirements and the respective standards (IEC 60076-3). In this paper, induced over voltage testing on transformers using enhanced Z source inverter is discussed. Power electronic circuits are now essential for a whole array of industrial electronic products. The bulky motor generator set, which is used to generate the required frequency to conduct the induced over voltage testing of transformers is nowadays replaced by static frequency converter. First conventional Z-source inverter, and second an enhanced Z source inverter is being used to generate the required voltage and frequency to test the transformer for induced over voltage test, and its characteristics is analysed.

We consider the output feedback event-triggered control of an off-grid voltage source inverter (VSI) with unknown inductance-capacitance (L − C) filter dynamics and connected load in the presence of an input disturbance acting at the inverter. Due to uncertain dynamics and unmodeled parameters in the L − C filter connected to the VSI, we use an adaptive observer to reconstruct the system's states by measuring only the voltage at the output. The control mechanism is constructed based on an impulsive actor/critic framework that approximates the cost, the event-triggered controller, and the worst case disturbance and generates the desired AC output with the least energy dissipation.We provide rigorous stability proofs and illustrate the applicability of our results through a simulation example. KEYWORDSactor/critic structures, event-triggered control, output feedback, VSI, zero-sum game INTRODUCTIONGrowing concerns about fossil-fuel reserves, energy security, and global warming have drawn a lot of attention to renewable energy resources. 1 The increasing use of such resources 2 with intermittent generations requires "smarter controllers" for balancing power consumption and generation, often through energy exchange. In an electrical utility grid, batteries exchange energy in the form of direct current (DC) electricity. Although there are different applications that can use DC directly, various types of applications require a voltage source inverter (VSI) to convert a DC voltage to an AC voltage. The VSIs are widely used for various high performance applications, such as AC motor drives, uninterruptible power supply systems, electric vehicles, reactive power compensators and active power filters, AC power supplies, and grid connected schemes. 3,4 Recently, many researchers have focused on high performance control of VSI (see the works of Vamvoudakis and Hespanha 5,6 and the references therein).
