The HV Diagnostics HVA120 VLF High Voltage Insulation Test Set is a powerful 0.1 Hz VLF cable test system for testing of medium voltage cables, 0 – 120 kV peak, 0 – 85 kV rms.READ MORE >>
Diagnostics of medium and high voltage cables provides the opportunity for early detection of weaknesses and preventative maintenance work to be carried out before the cable fails in service. Partial Discharge diagnostics (PD) allows a precise analysis of cables and their joints and terminations. Tan Delta diagnostics (TD) provides a clear statement about the overall dielectric condition of aged polymeric cables.

Transformers can sometimes experience significant physical stresses whenever they are moved from one location to another, such as when they are initially shipped from the manufacturer. Once they have been placed into service transformers can also experience tremendous stresses related to being in the path of fault currents when something goes wrong in the electrical system. The combination of mechanical and electrical stress can cause the transformer to prematurely fail. Symptoms may not be obvious until the damage is already extensive. Performing sweep frequency response tests can be used as an early identifier problems that occur as a result of physical changes within the transformer.READ MORE >>

Vanguard's EZCT series of current transformer testers are designed to be rugged and portable, ideal for industrial and field applications. They can perform the CT excitation, polarity and ratio tests. These testers allow you to test current transformers in their field-mounted configuration. This reduces the need to remove the CT from the host electrical component.READ MORE >>
Locating cable problems through visual inspection, continuity and insulation resistance testing can be difficult and time-consuming especially on long installations. To help you save time, effort and money in troubleshooting cables, consider using a Time Domain Reflectometer. This diagnostic tool is very efficient and accurate because it can help localize the fault from where you are in a matter of seconds. After prelocating the fault, you can then run other diagnostic techniques to verify the defect. Time domain reflectometry is not only effective in finding faults in electrical cables. It can also be used for various installations for cellular, telephone and cable TV installations.

A ground is a crucial component in any electrical system. It routes electricity to the Earth when electrical insulation fails. Ultimately, it provides a definitive path in theses instances and prevents the electrical path from including anyone or anything else. Additionally, enclosures for electrical apparatus as well as radial conductors for cabling are often grounded in order to provide shielding from electrical noise or radiated interference.READ MORE >>
Power factor testing is a diagnostic test that is commonly performed to quantify and trend characteristics of electrical insulation. A regular testing and maintenance program that includes power factor testing can aid in determining the health of electrical insulation as well as where it is in its life cycle and how to plan for taking it out of service.READ MORE >>
