The obtained C and tan δ values interruption test system with current rating of 32 Amps.” for its bushings and windings were found to be satisfactory. Today, most of the electrical and electronic equipment may be 5.2 Research and Development Projects completed: affected by voltage dips, short interruptions or voltage variations of power supply. These voltage dips and short Following R&D projects were completed recently - interruptions are caused by faults in the network, in installations or by a sudden large change of load. In certain 5.2.1 “Development of Polymer Nanocomposites with cases, two or more, consecutive dips or interruptions may Nano carbon for Shielding of Electromagnetic Radiation.” occur. Voltage variations are caused by continuously varying loads connected to the network. Hence, the voltage dips and Most of the electrical and electronic devices generate interruption testing of any electrical or electronics product is electromagnetic (EM) radiation, for example laptops, mobiles, necessary as per IEC 61000-4-11 standard & this project was energy meters, etc. Electromagnetic radiation may interfere taken-up to ful ll the requirement for 3-phase supply. with functioning of electronic equipment and needs to be eliminated by means of proper shielding materials. Therefore shielding materials play an important role in functioning of electronic devices. Traditionally, metallic materials are used for EM shielding which functions as a Faraday Cage. Metallic conductive material distribute and dissipate external electric charge thereby reducing the EM radiation. However, metallic materials have limitations like high cost and weight. Therefore, polymer composites are often used in shielding applications. However, these composites contain high ller content to obtain the required EM shielding property. Such high ller ratio could adversely affect the properties of composite material making it brittle. Nanocomposite offers a new avenue to develop materials for electromagnetic shielding. ERDA has developed polymer nanocomposite with Nano carbon to attenuate the EM radiation in frequency range of 1 GHz to 18 GHz. EM radiation level detected before and after shielding with nanocomposite material is shown in Fig 5.2.1 (ii) Developed Voltage Dips and Interruption test panel Fig 5.2.1 (i)Un lled polymer sheet (left) and nanocomposite sheet (right) Fig 5.2.1 (ii) Level of electromagnetic radiation(a)Electromagnetic radiation generator is open Captured Voltage dips waveform across (not covered) (b) EM radiation generator source covered with sheet of polymer nano composite output terminals of Designed Panel 6

Induction motor acoustic waves, emit light and produce chemical (IM) is a well-established technology and mostly used in decomposition of insulation materials; these physical and industrial application due to its robustness and simple chemical effects can be detected by various diagnostic realization. However, induction motor works with lower power methods and appropriate sensing elements (sensors). Besides density and ef ciency when compared to other motor the so-called 'conventional', electrical method described in IEC technologies. Synchronous reluctance motor comes with 60270, it is possible to detect and measure PDs with various standard AC stator and salient type rotor works on the principle 'non-conventional' methods. There was a special need to give of reluctance variation with rotor position. There are no rotor recommendations for the two used non-conventional winding or bars which not only eliminate rotor losses and methods, acoustic and electromagnetic ones and this project heating but also provide a better dynamic response. is the rst step in this direction. Major challenge faced in design of synchronous reluctance motor is to achieve a higher saliency ratio (Ld/Lq). This ratio is Gas-insulated switchgear (GIS) have been in operation for a vital parameter in achieving higher torque/ampere and power more than 45 years and it shows a high level of reliability. factor of motor.

The design of motor is taken from a 2.2 kW IE4 induction motor Ultra-High Frequency (UHF) measurement method, which was developed by ERDA. introduced in the late 1980's for PD detection can be used by utilities for continuous monitoring in service. The UHF method 7 is less sensitive to noise, so easier to handle in comparison with the conventional method. This project collected the available experience and described its practical applications for GIS. A detailed description of the procedure was given; supported by proper sensor placement at site. Guidelines will help utilities for the effective application of the UHF method for online PD detection on their GIS systems. 5.2.4 “Development of Synchronous Reluctance Motor with drive for automobile application.” Current research on electrical rotating machines, concentrates to develop motor technology to reach IE5 class ef ciency.
