ASPEN Relay Database™ is designed to be a repository of relay information for electric utilities and industrial facilities. The Relay Database is unique in its flexibility. You can customize the database for any relay type, including, but not limited to, overcurrent relays, distance relays, differential relays, and voltage relays. The database is capable of handling electromechanical relays with just a few setting parameters to modern microprocessor relays with hundreds of parameters. You can store one or more sets of setting parameters. Some of these can be historical. Others can be emergency or pending settings. You can also store test results.

You can even customize the labeling on the forms. This feature gives you the flexibility to change the data identifiers. It also lets you change the labeling from English to the language of your choice.

In addition to relays, the database lets you store information on circuit breakers, transformers, current transformers (CTs), potential transformers (PTs), communication equipment, and three user-defined objects.

The program comes with many commonly-used reports for your convenience. You can generate a report from within the data forms and from the Report Gallery. You can customize any of the reports or create new reports with the powerful build-in report designer.

Security is built-in. The database administrator can control access to the database on a form-by-form basis. The robustness and security of the database have been proven with many installation-years of constant use. The largest installation of the Relay Database contains over 10,000 relays and a million setting parameters. Other advanced features include:

• Ability to store files as binary objects within the database tables. With this feature, you can store in the database manufacturer's relay and test files, as well as drawing files and trouble reports.
• Ability to create links between different objects.
• Ability to link external files and web addresses to objects in the database.
• Ability to transfer relay-settings data in both directions between the Relay Database and an SEL-5010 file.
• Ability to transfer relay-settings data in both directions between the Relay Database and an SEL-5030 AcSELerator file.
• Ability to import relay-settings data from GE, AREVA, ABB and other relay vendor software.
• A web interface is available at no additional cost.
• Data backup and restore (Client/Server version only.)
• Detailed audit trail for all changes (Client/Server version only.)
• Briefcase mode (Client/Server version only) which enables a user to take a subset of the data on his or her laptop and work off-line. The user can synchronize the main relay database with his changes to the briefcase file at a later time.
• Ability to work with languages other than English.

Three versions of the Relay Database are available: the Unlimited Version using Access tables, the Client/Server version with Oracle and the Client/Server Version with Microsoft SQL Server. In all cases, the Relay Database runs on PCs under Microsoft Windows XP, Vista and Windows 7. The database is network ready and is designed to let many users access and modify the information simultaneously. There is no practical limit on the number of simultaneous users.

The ASPEN Relay Database is written by relay engineers for relay engineers. It is a turnkey solution for relay engineers who need a relay database but do not have the time or in-house expertise to create one. It is also an attractive solution for those who want to move their data from mainframes to the PC platform.
