For technical reasons there is a download limit ofrecords per data query, but there is no limit on the number of data queries a user can do. This limitation will be relaxed further, as the technical computing capacity is expanded. For background information, please read the full announcement. Access trade data through API. Build your own trade data applications! Enter country name, commodity or year and this data mining tool will give an instant overview of data you are looking for.
Thereafter, you can dig for more refined data. This is a repository of background information on UN Comtrade.

This is only applicable to subscribers. Nevertheless, all users should understand the limitation of trade data. Read Data Disclaimer.Devastating meaning in punjabi
For data, you can enter only commodity code or text, partner or reporter code or name, and related commodity trade variables. The output would yield several pages with the results in tag clouds. For example, the search term could be the name of the country, the country's abbreviation, a commodity key word or a year. Examples: "aircraft" or "aircraft engine".
The tag clouds appear as years for which the commodity selected is available. The first result shows that year has the largest value for that commodity. The system will search the latest available data. You can search for commodities within the commodities tab. Within the reporters tab you can select one or more reporters from the drop down list or choose your customized country groups or my favorite reporters.
The latter two options are available to UN Comtrade subscribers only. It is the same for partners tab also. You can select years depending on your need in the years tab.Inquilino significato per bambini
The others tab allows the user to filter trade data by value and also allows the user to choose a preset sort order. After choosing all the appropriate options for your query you can save your query for future use. You can also allow for batch notification. Batch notification will send a notice to your email address once the query execution is completed.
Please note these two options are also limited to subscribers of the UN Comtrade database only. It too has all the features of the Basic Selection query but in a more compact window. For commodities, you have the option to choose individual commodities or just chapters.

Thanks to the powerful math on the recorded voltage and current signals, Wavewin is able to calculate the fault location and the fault resistance, giving valuable information to the relay engineer on how to optimize the relay settings with the experience gained by the transient recording of the power system faults. The software is a specialized, high-resolution graphic interface designed for universal management, display and analysis of digital fault records.
Standard CSV format is also supported which also allows for trending of periodic load measurements over long periods of time. Wavewin supports additionally a long and growing list of proprietary disturbance recorder file formats. The product is recognized for its effectiveness in reading various implementations of the COMTRADE standard from various producers of intelligent electronic devices IEDs such as numerical relays, digital fault recorders, and disturbance monitors.
It provides fast sort and query engines, smart copy, move, and delete methods, and it allows for appending and merging of multiple records. The product is loaded with analysis features including waveform plots, phasor diagrams, sequence of events reports, harmonic tables, software channels, circular charts, and is equipped with an array of calculators for calculating frequency, sequence components, and fault location both single and double ended algorithms are provided.
Such errors hinder the analysis process and are difficult to find manually. Imagine trying to find one extra comma among hundreds of analog and digital channels. We tested at 10 major beta sites and the latest version can detect over 80 types of errors.
CCC also now comes with waveform plotting. It includes drivers for reading proprietary formats from various IED producers. It provides macros for creating inputs to short circuit simulation and modeling applications. It is also equipped with expert system modules for ranking fault records based on targets, magnitude, and durationand for trending periodic load measurements over long periods of time based on overload, imbalance, and efficiency.
Provides calculated channels for modeling of missing phases, sequence components, fault resistance…Creates combined event sequences from various types of digital fault records.
