A prototype of a pulsed plasmatron containing semi-open cylindrical chamber with electrically exploding
copper conductors of large cross-section creating pulsed toroidal magnetic field, as well as electrically
exploding thin wires to create dense plasma being installed has been created and researched. The principle
of operation of the plasmatron is based on excitation of an induction discharge during the decay of magnetic
field in plasma created by electric explosion of thin wires. The authors have shown that in this case, autonomous
plasma formations with anomalous afterglow (about 60 ms) are formed. The aim of the work is to create
a pulsed plasmatron with an inductive discharge, as well as to experimentally estimate the parameters of
device prototype.

Key words: pulsed plasmatron, metal electric explosion, pulsed magnetic field, induction discharge,

long-lived autonomous plasma formations.

The effect of helium, neon, argon, and hydrogen additions on the average radiation power level and the
maximum pulse repetition rate in a low-pressure nitrogen laser pumped by a longitudinal discharge is studied.
It was found that the introduction of helium, neon, argon, and hydrogen into the active element of a nitrogen
laser with a partial pressure of 5 Torr at an optimal nitrogen pressure of 18 Torr promote an increase
in the average radiation power level by 20 – 30 % and does not affect the maximum pulse repetition
rate. The addition of neon or argon to pure nitrogen does not lead to noticeable changes in the average radiation
power and the maximum pulse repetition rate. In an active element made of beryllium ceramics
300 mm long and 4 mm in diameter, the maximum values of the average radiation power of up to 115 mW
were achieved in pure nitrogen (РN2 = 18 Torr), 120 mW when using nitrogen with the addition of hydrogen
in the ratio РN2 : РH2 = 18 : 5 Torr and 140 mW when using nitrogen with the addition of helium in the ratio
РN2 : РHe = 18 : 5 Torr at the maximum pulse repetition rates of 500 – 600 Hz.

Key words: low pressure nitrogen laser; average radiation power; radiation energy in a pulse; the duration

of the radiation pulse; longitudinal discharge; metastable states; pulse repetition rate

Microgrid based on renewable energy sources is widely used in many power supply systems of small
communities. Solar power plants and wind turbines are often used to generate electricity. For the stable operation
of a microgrid, it is important to ensure its operational management and the ability to monitor energy
consumption. The microgrid control system based on things solves the problems of collection and processing,
object management.
The purpose of this work is to study the use of IoT technologies in microgrid management. Regarding
the work of a microgrid based on a solar power plant and a wind generator in Central Europe, Russia. Conducted
research on the possibilities and ways of using IoT technologies to control and manage microgrids
based on renewable energy sources.

Key words: Internet of Things, microgrid, solar energy, wind energy.

The problem of determining the factors affecting mechanical strength of uncontrolled high-pressure
spark gap-sharpeners designed to generate voltage pulses with an amplitude of up to 500 kV with rise times
of a fraction of a nanosecond is considered. The aim of the work is to determine by calculation and by direct
testing the structural strength of a spark gap-sharpener with working pressure of up to 120 technical atmospheres
(kgs/cm2). It was found that when preparing uncontrolled sealed-off high-pressure spark gapsharpeners
in metal-ceramic versions of RO – 48, RO – 43, RO – 49 series with optimal geometric dimensions,
from the viewpoint of ensuring necessary electrical strength, when manufacturing a 12H18N10T stainless
steel case with wall thickness of 2 mm and high–voltage cone-shaped insulator made of aluminum oxide
ceramics of VK94-1 (22HS) type with wall thickness of 3 mm, they can be filled with working gases up to the
pressure of 120 technical atmospheres.

Key words: spark gap-sharpener, mechanical strength, ceramic insulator, operating pressures, argon

arc welding, metal-ceramic soldered joint.
