"It's like consulting a resident expert"

This computer program is a must for Communication Engineers in the Power Industry, Electrical Protection Engineers in the Telephone Industry and Tradesmen in both industries

GPR Expert pays for itself in its first use!  This long overdue computer program includes the most robust calculation program on the market for computing GPR (Ground Potential Rise) levels, 300 Volt-Point-Peak and 650 Volt-Point-RMS distances, parallel induction voltages, and total wire-line communication Stress Voltages. Complex calculations are now done in seconds.

"Having GPR Expert is like consulting a resident expert."   GPR Expert is a computer program for the beginner as well as the expert.  This CD-Rom will work with Microsoft Windows 3.1, 95 or 98.  It offers both a detailed tutorial on High Voltage Special Protection using a High Voltage Interface (HVI) and the most robust GPR calculation package on the market. This program explains not only the details of how to properly install isolation protection, but more importantly the "WHY" -- so the installers really understand the design and won't make errors that result from not appreciating certain details that are really critical.

It's a fact that people do really expert work when they fully understand the reasoning behind what they are doing. The people who do the installations need this program so they don't have to depend on engineering staff who are often too busy to attend to the "little things." In a deregulated market, more independent and knowledgeable tradesmen mean lower installation and maintenance costs and more competitive power and communication prices.
