Simple Set-Up

The ACVGD® Ross Meter® takes less than 30 seconds to set-up whereas other applications and devices require 90 or more minutes to safely initiate. Faster set-up times equal faster project completion times.

Quickly Locates a Fault

The operator usually locates the fault within 10 to 15 short minutes after a brief set-up. Digging can begin much sooner than with other methods and instruments. When used properly, the meter's performance is exemplary.

Rugged, Dependable, Affordable

The ACVGD® Ross Meter® has been proven in the field and trusted by Linemen for over 30 years. It is proudly built in the United States by workers who stand behind a quality American product.

“I worked for Dominion Energy for 35 years. I am now retired. I used the Ross Meter for 30 years. If you were trained properly with this meter and use it properly, it is the best secondary fault locator on the market. It is very efficient and durable. It’s saved me a lot of time and headaches and I would not use anything else!” – Robert L.

Safety

Operators are not required to isolate the source or load because the ACVGD® Ross Meter® makes use of the existing 60 hz A.C. voltage that is still energizing the faulted cable. The Ross Meter® is passive and is never connected to the load or the cable in question.

Efficiency

Use of the ACVGD® Ross Meter® effectively results in a 90% reduction in set-up and operation time. The operator merely walks out to where the cable is buried and begins to probe along the path of the cable. The Ross Meter® does not require the operator to place a signal onto the faulted cable.

Cost Effective

The ACVGD® Ross Meter® is easy to use and its application to the job of locating the precise location of the fault can be mastered in just a few times of use. Time is money and this tool provides the user the ability to quickly locate faults which in turn reduces global costs for your company.

Conservation

With greater efficiency and no excessive energy used to troubleshoot the problem, the Ross Meter® reduces costs and saves energy. Even though energy conservation reduces energy services, it can result in increased safety for the men on site and higher cost savings for your company.

Frequently Asked Questions and Instructional Video

All cable insulation deteriorates naturally with age, especially when exposed to elevated temperature due to high loading and even when it is not physically damaged. The result is a distributed flow of current leakage. An interruption of power service may result. Many substances such as water, salt, oil and chemicals can contaminate and shorten the life of insulation and cause serious problems. Some types of insulation are subject to a condition termed 'treeing'. It has been found that the presence of moisture containing contaminants, irregular surfaces or protrusions into the insulation plus electrical stress provides the proper environment for inception and growth of these trees within the insulation material. Testing indicates that the AC breakdown strength of these treed cables is dramatically reduced. Damage caused by lightning, fire, or overheating may require replacement of the cable to restore service.
New construction or landscaping work may result in an underground cable being damaged. A previously repaired cable may have a splice that has failed. But many times the insulation can be the suspect. When at some local point in a cable, insulation has deteriorated to a degree that a breakdown occurs allowing a surge of current to ground, the cable is referred to as a faulted cable and the position of maximum leakage may be considered a catastrophic insulation failure. At this location, the insulation or parallel resistance has been drastically reduced and a spark gap has developed.
Since September of 1974, the ACVGD® Ross Meter® has been working in the field and continues to claim a 98% capture rate on faults due to damaged sheathing. The ACVGD® Ross Meter® is a passive device. Unlike other devices which locate faults, the ACVGD® Ross Meter® does not require that the buried line be isolated in any form or fashion. The power to the line does not need to be turned off. The line itself does not need to be disconnected from the transformer pad nor the service panel. No additional devices are required to be attached to the line, such as a thumper or signal generator. The operator does not need to know the cable's path. The operator of the Ross Meter® simply walks where the cable might be, watches the meter reactions to the voltage patterns in the soil and locates the fault. This translates to shorter set-up times and shorter seek times. The ACVGD® Ross Meter® quickly, effectively and efficiently identifies direct buried secondary cable faults. Whether industrial, commercial, residential or with street light applications, the Ross Meter® is the preferred device used to identify faults. And one last point, the Ross Meter® costs alot less than most devices used to locate faults. For more information, please read the user manual.
Under typical conditions and with proper use, the operator can usually locate a fault within 10 to 15 minutes after arriving on scene.
1. The Ross Meter® is sensitive only to alternating current gradients. It is self-protected for 60HZ voltages up to 300 volts RMS.

2. The Ross Meter® can take you directly to the fault. The operator need not know exactly where the service cable is buried. He or she can make an educated guess as to where the service cable runs between the transformer and the load and then choose a point somewhere in between to begin detection using the supplied probes.

3. Absolutely no connection of any equipment to the customer's service or street light cable is necessary. The operator merely takes readings of the AC Voltage Gradient flowing in the soil due to the leakage from the damaged point of the cable.

4. The ACVGD® Ross Meter® typically detects the fault from a distance of 25 feet and often times to 75 feet when the earth is damp.

5. The work required to locate the fault is a one man operation when using the Ross Meter®.

6. The Ross Meter® has a rugged design. The internal circuitry and careful wiring methods assure you years of safe and trouble free operation. The neck strap is comfortable and convenient for the operator. A tough carrying case is included to store and protect the meter.

7. Two 9 volt batteries are required to power the unit.

8. The probes are constructed to keep the operator safe at all times during operation.

9. We provide a 1 year Warranty on parts and labor except for breakage. The probes are warranted for a period of 90 days. Batteries are not covered by this warranty.

10. The price of the Ross Meter® is very affordable when compared to the cost of other commercial devices used to located faults.
Most field service men prefer using other units that place pulsed DC on the street light circuits to locate those types of faults. The ACVGD® Ross Meter® is best used to locate underground faulted services to buildings.
