The ASPEN Relay Database is designed to store the physical and electrical data of relays and related equipment (including breakers, CTs, PTs, and communication equipment). By physical data we mean the actual knob and dip-switch settings of the older relays and computer settings of modern digital relays. This is in contrast to the electrical data required by OneLiner for short circuit simulation and relay coordination. Examples of the electrical data of a distance relay are the reach, characteristic angle and time delay of each zone.
The ASPEN Relay Database is ideal for keeping settings and maintenance records of relays and breakers, but it is not necessary to run OneLiner. For this reason, the Relay Database is not a standard part of OneLiner and must be purchased separately.
If you have OneLiner and the Relay Database software installed on the same computer, you can enable a direct, bidirectional transfer of electrical and physical data between the Relay Database and OneLiner.
Several versions of the ASPEN Relay Database are available, including an Unlimited Version that utilizes MS Access tables as storage media, and two Client/Server versions that utilize Microsoft Sql Server and Oracle engines.
