Trichel Pulse Analysis: Physical Calculation and Validation by Using Broadband Measurements

Partial discharge measurement is part of the monitoring of equipment in power engineering systems. It provides important information about the condition of the equipment and in particular the condition of the insulation components. This information serves to take necessary preventive measures at an early stage to avoid failures of the affected energy system and thus ensure a high level of energy supply security. Possible causes of partial discharges in energy technology equipment include high field strengths at edges with small radii or defects within insulation materials itself. Depending on the location and extent of the occurrence, partial discharge events may cause lasting damage to components of equipment. In order to be able to interpret the measurement results of partial discharge monitoring with regard to the exact cause and, if necessary, to evaluate them automatically, a precise understanding of the physical phenomena that occur during a partial discharge is necessary. The physical replication of a partial discharge pulse helps to better understand, evaluate, and interpret measurement results and thus create a synergy between measurement data and model-based results.

Analisis Sistem Akuntansi Persediaan Bahan Penolong Terhadap Pengendalian Internal CV Bumi Nusantara

The study aims of analyze and evaluating the accounting system for component inventory and internal control of CV Bumi Nusantara. This type of research is qualitative research with a case study method, through direct observation and structured interviews. Data analysis is performed is an analysis of component inventory systems and analysis of internal controls related to organizational structure in separating duties and responsibilities, authority systems and procedures of enumeration as well as healthy practices that cannot be separated from competent employees. The results showed that the procedures in the accounting system for component inventory carried out by CV Bumi Nusantara has run well but there are still weaknesses and shortcomings in the documents, records and functions related to the system and procedures. There is still a dual role in the function carried out with no separation of duties in the procurement and warehouse division, some documents are not in the company, do not record in the journal. In addition, the physical calculation system that is carried out needs an evaluation because it is only done by the warehouse. A good component inventory accounting system is very influential in improving the internal control of CV Bumi Nusantara because the network of procedures, documents, records and functions will affect the running process of an existing internal control, with the completeness of documents, records, and functions related to the supply of component will facilitate the internal control of CV Bumi Nusantara and improve the level of reliability of accounting information.

IMPROVING THE EFFICIENCY OF THE UNIT OF THE ZAPORIZHZHIA NPP WITH A WWER-1000 REACTOR

Improving the efficiency of the unit of the Zaporizhzhia NPP with a WWER-1000 reactor, by reducing the water temperature at the inlet to the condenser. The work describes the description of the NPP and the nuclear power reactor WWER-1000, by reducing the water temperature at the inlet to the condenser. Detailed neutron-physical calculation of the nuclear power unit with WWER-1000 reactor with a turbine installation K-1000-60/3000. The influence of the temperature of cooling water on the input to the capacitor and the load on the efficiency of the turbine installation and the flow of steam and heat to the turbine installation is established.

Effects of different nuclear evaluation data on the RMC keff calculation

Neutron cross section data is the basis of nuclear reactor physical calculation and has a decisive influence on the accuracy of calculation results. AFA3Gassemble is widely used in nuclear power plants. CENACE is an ACE format multiple-temperature continuous energy cross section library that developed by China Nuclear Data Centre. In this paper, we calculated the AFA3G assemble by RMC.We respectively used ENDF6.8/, ENDF/7 and CENACE data for calculation. The impact of nuclear data on RMC calculation is studied by comparing the results of different nuclear data.
