Using Bare Conductors on the overhead distribution lines in forest and wild life sanctuaries resulting fatal accidental death of several wildlife animals and big birds due to electrocution. - Manish Patel

Supercapacitor also known as electric double layer capacitor is emerging as a new energy storage device. Due to its high power density, wide thermal operating range, low cost, and long cycle life, it bridges the gap between battery and conventional capacitor. However, it has lower energy density than batteries. Electrode material plays a key role for improving the capacitance, and hence energy density of supercapacitor. In leading research and development organisations in the world, research works are going on in search of new electrode materials for improving the capacitance of the supercapacitors. This article presents a new approach to synthesise activated carbon from leaves of trees as an electrode material for supercapacitors. Activated carbon obtained by such process can be cost effective and also environmental friendly...- Gaurav Shekhar,Ashutosh Phatak, Dr PB Karandikar,Prof Swati Shirish More

The most common solution to harmonic problems involves the application of harmonic filters. Capacitors and the system short-circuit impedance combine to create resonances that can magnify harmonic levels to well above accepted limits. What is the solution? - Dr L Ashok Kumar

Ultracapacitors have large energy densities – up to 1/10th of battery or even more, but their strengths lie in high power delivery... - R P Deshpande

Capacitors mostly start getting damaged due to repeated voltage fluctuations (exposure to higher voltage)…

Supercapacitors and ultracapacitors are one and the same. The difference in the nomenclature can be attributed to the Europeans and the Americans. Europeans call the same device supercapacitor while the Americans know it as ultracapacitors... - Dr P B Karandikar, Dr N R Kulkarni,  Seema Mathew

Reduction of heat transfer from outside to inside of a building lowers the cost of (electricity) cooling during summer days...

Power factor is the ratio between the KW and the KVA drawn by an electrical load. Where the KW is real power to load and KVA is the apparent load power. It is the measurement how an electrical equipment getting current in actual. A load with power factor of 0.85, results much higher losses in supply system and consumer has to pay higher bill… - Anuraj Kumar

In previous publications, authors have reported about the performance of the single-phase inverter topology based on controlled charging of the capacitor. The dynamic performance was not available. This article presents the dynamic performance of the inverter for various types of load, which includes leading, lagging and unity power factor, and analysis for 'total harmonic distortion' has been included... - K.Vijayakumar, S.Kannan and S.Ponnayira Sundaravel

It is also an important factor for selecting the type of cable. It is to be kept in mind that the cost of the cable should not be such large that it causes loss and another cable may fetch the same results in low cost and loss…- Jignesh Parmar

The combination of Active Front-End Converter and variable frequency drive gives accurate speed control and dynamic braking.

In the recent past battery and fuel cell technology are undergoing rapid advancements. The supercapacitor technology has to overcome these devices in economy, performance and utility to make itself a viable option. Thus the challenges faced by this technology are unique.

This will form part of the portfolio led by Mark Kempton, the company's Business Unit Director for Semiconductor Devices.

The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…

Mitsubishi Electric Corporation revealed that it has developed a 6.5 kV full silicon carbide (SiC) power semiconductor module that is believed to offer the world's highest power density (calculated from rated voltage and current) among power semiconductor modules rated from 1.7 kV to 6.5 kV.
