Electrostatic discharge is a familiar interfere. Repeatability of discharge current is poor. Transmission line pulse (TLP) is used in study of immunity of a microcontroller. A TLP generator is first manufactured with the rise time of output pulse less than 1ns. Then couplings by electric field probe, magnetic field probe and direct injection are presented. And immunity test of a microcontroller is done by using the TLP generator and probes. Results show that the tested microcontroller is more sensitive to magnetic field interference; reset pin and crystal oscillator pin of the chip are more sensitive than other pins under action of direct injection interference.

Abstract The paper describes a semiconductor picosecond pulse generator that can be used to calibrate capacitive high voltage sensors of MV range. The generator is designed as a base unit, to which external pulse converters are connected. In the base unit, semiconductor devices – first a semiconductor opening switch (SOS) and then a semiconductor sharpener (SS) – generate an output pulse with a rise time of 220 ps and a subsequent flat-top of 2 ns in duration. The pulse amplitude is around 1 kV across 50 Ω load. An external diode sharpener generates a pulse with 120 ps rise time and 500-ps flat-top at the amplitude of 850 V. To switch the semiconductor sharpeners to the conducting state, the shock-ionization wave mode is used. Additional pulse converters make it possible to generate output pulses across 50 Ω load with the rise time of 70-150 ps, the pulse duration of 135-310 ps, and the amplitude of 130–480 V. The electrical diagram of the generator and waveforms of the output pulses are presented. An example of the calibration of capacitive sensors of a multi-gigawatt picosecond generator is also shown.

Human population and power consumption keeps on growing with each year. In order to satisfy electricity demand, more electrical energy has to be supplied, resulting in higher magnetic field level radiation. In rapid urbanization country, lack of space will force civilization to be built near overhead transmission line that sparks public concern on adverse health effects due to the magnetic field radiation. A new UTHM hostel residential area was built near OTLs that shared the same concern. Thus a proper planning to conduct magnetic field level measurement was done to examine the maximum magnetic field level radiated that covered the hostel residential area. The results were far from reaching the maximum permissible magnetic field level proposed by ICNIRP. Though, the steps taken and the methods used might be suitable guidelines for others that encounter similar situations.

With rapid industrial and commercial growth and flourishing population, power demand is increasing rapidly. Modern methods of UHV transmission lines are important to transmit bulk amount of power more efficiently in comparison to earlier methods of transmission. 1200 KV UHV transmission line is India future and therefore forthcoming project to tackle this situation. However as line to line voltage level increases, complexity of the transmission line increases. But, with higher level of line to line voltage, complexity of transmission line increases. ROW is one of the major concerns with transmission lines. Many parameters need to take care in designing; one of them is a magnetic field distribution at surroundings of transmission line. India has initiated to expand its UHV range to 1200kv. Paper suggest magnetic field of three configurations of the 1200KV line. Horizontal and vertical configuration test lines have been installed. Analysis has been done by two methods finite element method and (Method of images) analytical method. FEM is used to solve partial differential equations. Results from both methods have been compared. 3D electric field analysis of configuration also performed. Plotted results are compared with ICNIRP standards and safety limits defined. Adverse effects of excess magnetic field is also discussed. Biological effects of electromagnetic field on people, animals and plants are also discussed. Thus paper aimed at magnetic field calculation and verification with respect to standard. It also helps to utilize less right of way. The subject is under broad development due to its advantages over lower voltage levels and holds significance in future as well.
