History of the ACVGD® Ross Meter®

In Memoriam


Mr. Herman B. Ross Jr., 75, of North Chesterfield, Virginia, passed away on November 12, 2014. After graduating from Columbia High School in Columbia, South Carolina he served in the U.S. Air Force and attended the Air Force Electronics School in Denver, Colorado. Afterwards he attended the University of South Carolina and received a B.S. degree in Electrical Engineering in May of 1965. In June of 1965, he began to work for VEPCO in Hampton, Virginia. He retired from Dominion Virginia Power in Richmond, Virginia, having worked there for 30 years. He was an electrical engineer, supervisor, district manager and project manager. He was also the inventor of the ACVGD® Ross Meter® and owner of the HB Ross Manufacturing Company. He is survived by his family and friends. Memorial services were held at 2 p.m. Saturday, December 13, at Southside Church of the Nazarene, 6851 Courthouse Rd., Chesterfield, Va. 23832.

First Published Article


In May 1965, Herman B. Ross, Jr. and R.E. Alley, Jr. jointly published this article in The Physics Teacher while each were attending the University of South Carolina. Experiments that they conducted and documented within this article consisted of a Rectifier experiment, a Voltage Doubler/Tripler/and Quad circuit experiment, Diode Clipper circuit experiment, Single Stage Transistor Amplifier experiment, a Wien Bridge Oscillator experiment, a Free-Running MVBR experiment, a Peaking Circuit experiment, and a Linear Sweep Generator experiment.

The Concept


In an effort to become more productive, time effective and efficient, H. B. Ross, Jr. designed and developed the passive process to locate direct buried secondary cable faults in 1973. Like most inventions, the ACVGD® Ross Meter® began as a passing thought and Mr. Ross maintained that it was a God given inspiration which later produced this original concept drawing in 1974.

The Prototype


From concept to prototype, the unit you see here was put into the field for testing by linemen in September of 1974. Valuable feedback was received which included physical characteristics that needed improvement to make it more rugged and functional in the user environment. Field tests continued through 1975 when the HB ROSS MANUFACTURING COMPANY was formed.

First Production Unit


Here is a recent photo of one of the first units that went into production at the HB ROSS MANUFACTURING COMPANY. This particular unit was used by VEPCO linemen in the Virginia Beach, Virginia area for a few years then taken out of service in July of 1978. VEPCO by name has changed many times over the years, but it is now known as Dominion Energy.

The ACVGD® Today

Over the past 40 years, the ACVGD® Ross Meter® continues to have a 98% capture rate on faults due to damaged or degraded sheathing. It continues to prove its worth by locating the faults within 15 minutes or less. And it always provides a safer work environment for operators since no additional equipment is required to be connected to the customer's service.
