Title: Method of determining fault location of cable and overhead power transmission lines
Inventor: Kucheriavenkov Andrei Anatolevich
IPC: G01R31/08
Filed: 2020-03-31
Granted: 2020-10-07
Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to electric power industry, namely to methods intended for determination of electric network damage point. Essence: instantaneous values of current and voltage are measured at frequency of 50 Hz and frequency of 10 kHz of current and voltage by sensors located at the ends of power transmission line. Instantaneous values of current and voltage are compared in high-frequency range for determination of direction of single-phase ground fault as per mutual phase of said parameters. Instantaneous values of current and voltage are compared in low-frequency range to determine fact of single-phase or phase-to-phase short-circuit on power transmission line. When wave processes occur in the monitored line, the lines of voltage values controlled at both ends of the line are oscillographed by analogue-to-digital conversion with sampling frequency of 1 MHz with accurate referencing to common astronomical time using global satellite positioning system and with subsequent calculation of distance to point of power transmission fault by difference of arrival time of wave front to each of power transmission line ends. 
     EFFECT: technical result is higher accuracy of determining point of faults of power transmission lines due to combined application of wave analysis of processes occurring in electric networks, and wave method of double-sided measurements.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to the field of medicine, namely to thoracic and cardiovascular surgery, and can be used to close extensive defects of the anterior chest wall in order to stop and prevent the recurrence of the infectious process. To do this, a flap is formed from the greater omentum by isolating and crossing the gastroepiploic artery. The flap between the gastroepiploic artery and the large curvature of the stomach is mobilized. The flap is moved to the anterior chest wall in the anterior mediastinum. During the formation of the flap, the right gastroepiploic artery is isolated and crossed, followed by dissection of the greater omentum from right to left, after which mammary-gastroepiploic autovenous bypass surgery is performed between the right gastroepiploic and internal thoracic arteries. When dissecting the greater omentum, the right gastroepiploic artery is isolated and crossed along the large curvature of the stomach in such a way that the artery becomes part of the omentum flap.   
     EFFECT: method reduces the risk of rejection or necrosis of the flap of the greater omentum when closing extensive defects of the anterior chest wall by ensuring adequate blood supply to the distal parts of the displaced flap from the greater omentum.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to surgery, transplantology. The donor's duodenum is sutured on both sides, and arterial reconstruction of the splenic and superior mesenteric arteries is performed using a donor Y-shaped vascular insert. The recipient has an extraperitoneal approach from the symphysis laterally and upwards parallel to the inguinal ligament on the right. An area of ​​the small intestine with a length of 20 cm along Roux is turned off from digestion. An incision is made in the peritoneum with a size corresponding to the transverse size of the small intestine. Through it, the small intestine, turned off from digestion, is brought out into the wound so that its free end recedes from the peritoneum by 4 cm. A pancreatic graft (PG) is placed in the right iliac fossa along the wing of the ilium in an inverted position with the head downward, with the dorsal surface anteriorly. A venous anastomosis is formed between the PG portal vein and the recipient's right iliac vein. An arterial anastomosis is formed between the Y-shaped vascular insert and the recipient's right common iliac artery. Between the prepared duodenum of the donor and the free end of the recipient's small intestine, a side-to-side interintestinal fistula is formed. The surgical site is drained with two silicone drainage tubes placed above and below the pancreatic graft. 
     EFFECT: method allows preserving PG in case of its necrotic changes; allows to increase the duration of the functioning of PG and thereby increase the survival rate of patients with insulin-dependent diabetes mellitus, as well as reduce the number of insulin injections or completely abandon its intake; allows you to safely remove PG with minimal trauma in case of its dysfunction or necrotic changes, without requiring re-entry into the abdominal cavity.
