Do you know how (and why) to force neutral current through your protective relay systems?</SPAN></B></P>
<P STYLE="Text-Align : Center"><B><SPAN STYLE="Font-Size : Medium"><BR>
Can you predict the amount of neutral current flowing?</SPAN></B></P>
<P STYLE="Text-Align : Center"><B>All of the answers, and more, are available from this site. The software and
training that we offer can help you become a better Power Systems Protective Relay Technician.</B></P>
<P STYLE="Text-Align : Center"><B>This site will introduce you to some software tools that should be a part of
your protective relay maintenance tool kit. If you have a laptop PC running Windows<SPAN STYLE="Font-Size : XX-Small">(TM)
</SPAN>then these programs will help you in the field or in your training sessions. Imagine, finally being able
to calculate the many needed values that you encounter when testing complex protective relays.</B></P>
<P STYLE="Text-Align : Center"><B>The calculations that you will learn can be applied to generation (symmetrical
components) and transmission protective relays (apparent impedance). The confidence that you gain as a result is
immeasurable!</B></P>
<P STYLE="Text-Align : Center"><B>In addition to offering software for sale we can provide instruction at your
site. We will present lectures, give tests and load and demonstrate our software in your PC's. We attempt to take
the mystery out of relay testing. If you have basic trigonometry, an intro to power system protective relays and
a desire to understand more about what you are testing then we can help.</B></P>
