Settings Transfer Utilities
The easy way to share settings
Digital relays today are powerful and flexible, but you pay the price of working with more settings than you ever dreamed. Fortunately, CAPE models all digital relays with their named settings and helps you compute and store the setting values. Now, how do you move them to the relay, send them to your field technicians, or share them with your asset management software? Electronic transmittal with the help of the CAPE Settings Transfer Utilities is the way.
Our solution is centered on a small number of data tables, simplified in design, implemented in a near-universal database product (Microsoft Access), and collectively known as the Neutral Interface. "Neutral" really means "product neutral." Any user or third-party vendor is free to write software to link to this Access database file. Better yet, use our Settings Transfer Utilities. Either way, you can share relay settings of all kinds with whomever you wish.
Creation of a Neutral Interface database file is done with a few mouse clicks in the Database Editor. This capability is available to all CAPE users. The electronic file produced is a simple Microsoft Access ".mdb" file. It may contain as little as the settings for a single relay with one setting group or as many as your entire database. You may make as many such Neutral Interface files as you like.
The objectives and benefits of the CAPE Neutral Interface are:
Promote utilization of CAPE protection data elsewhere in the company
Simplify electronic transmittal of protective device settings
Give safe, controlled access to settings for relay testing
Be a stable format for interchange with third-party software, e.g. asset management and GIS systems
Client Access Program (CAP)
A field engineer or technician has full access to the settings in a Neutral Interface file through the CAPE Client Access Program (CAP). CAP is an easy-to-use mini database editor. Settings may be viewed, annotated, and modified. For most SEL relays, CAP will connect to the SEL5010 database for direct settings transfer, export or import. (The CAPE Database Editor also supports similar links to relay setting files for some Areva, Basler, General Electric, NxtPhase, Siemens relays, and for SEL relays supported by the SEL5030 product.)
Comparison and Upload Program (CUP)
Typically, field personnel will return Neutral Interface files to the protection engineering group. The annotations, tester's initials, and dates are valuable information that belongs back in the CAPE database. It may not be typical, but setting adjustments may have been made. This data cannot be blindly returned to the CAPE database; it ought to be reviewed first. This is the function of the Comparison and Upload Program (CUP), in concert with a protection engineer. The engineer selects a relay from the Neutral Interface and CUP highlights all changes for review and possible correction prior to optional upload. This same utility is an excellent tool for uploading relay data for the first time when the data originates from some other database that the new CAPE user has maintained previously.
Neutral Interface - a standard MS Access file of relay and recloser settings that is easy to create and transport.
Client Access Program (CAP) - a compact Neutral Interface file editor for field engineers and technicians.
Also interfaces with settings files supported by many vendors.
Comparison and Upload Program (CUP) - a tool to compare settings in a returning Neutral Interface file with those in the CAPE database before you upload them.
