Cable Testing & Diagnostics
High voltage cable test equipment is an easy-to-operate test solution for your cable testing needs and helps save companies and utilities significant money, reducing unnecessary outages, and optimizing maintenance planning/budgets.
Partial Discharge Test Equipment
Partial Discharge (PD) testing is a proven diagnostic method for non-destructive cable testing for many years. Using partial discharge measurement with source localization, direct allocation of partial discharge activity on cable segments, joints or cable terminations is enabled allowing for optimal asset management and planning of maintenance.
Tan Delta Test Equipment
High-precision tan delta/power factor measuring equipment are used for measuring very low dielectric losses in high voltage apparatus. Tan Delta / Power Factor is a precise and non-destructive method to provide important information on the extent of ageing in insulation systems. Tests are conducted during periodic maintenance and inspection of high voltage equipment such as power transformers, instrument transformers, bushings, capacitors, motors, generators, power cables, etc.
Test Bay Equipment
HV TECHNOLOGIES, Inc. specializes in providing High Voltage Test Systems for the generation of AC, DC, and Impulse voltage and current sources to meet your factory, laboratory, and on-site test requirements. Our product innovations and expertise provides your company with a solid return on investment.
Impulse Testing
Impulse testing systems are designed to generate impulse voltages that simulate lightning strikes and switching surges. HV TECHNOLOGIES has a long tradition of supplying impulse voltage generators for HV applications as well as impulse test systems for the EMC, avionics, and military industries.
Transformer Testing
Power and distribution transformers are among the most important and cost-intensive equipment in electrical power transmission and distribution. Therefore, their operation must guarantee a continuous and error-free power supply over decades.
Whether you need quality assurance testing following production or routine transformer testing, HVT has a solution for you.
Instrument Transformer Testing
Instrument transformers are important high voltage electrical devices that isolate and transform currents or voltages from higher magnitudes to lower magnitudes to provide safety of an end user and to protect a measuring device being used, such as a current or voltage measuring bridge, ammeter, or voltmeter. High currents are transformed using a current transformer (CT) and high voltages are transformed using a voltage transformer (VT), otherwise known as a potential transformer (PT).
Haefely / Tettex has a long-standing tradition of providing highly accurate instrument transformer test systems used to precisely measure current/voltage ratio errors, phase displacement, and excitation.
Calibration Equipment
HV TECHNOLOGIES, Inc. supplies various different calibration equipment for your high voltage testing needs with excellent results in accuracy and reliability.

What is Partial Discharge (PD) testing, and why is it important?
Partial Discharge testing is a diagnostic method used to detect localized dielectric breakdowns within insulation systems. Identifying PD activity is crucial for preventing insulation failure and ensuring the longevity of electrical equipment.
What is Tan Delta testing, and what does it measure?
Tan Delta testing measures the dielectric losses in insulation materials. A higher Tan Delta value indicates increased energy dissipation, which can be a sign of aging or degradation in the insulation system.
Can your equipment be integrated with existing test setups?
Yes, our equipment is designed with compatibility in mind. We offer integration services to ensure seamless operation with your existing test systems and infrastructure.
What safety features are incorporated into your hv test equipment?
Our hv test equipment includes multiple safety features such as interlock systems, emergency stop buttons, protective enclosures, and grounding mechanisms to ensure safe operation during testing.
How can I obtain technical support for your hv test equipment?
Technical support is available through our Support page, where you can submit a request or contact our support team directly at service@hvtechnologies.com.
How do I prepare my equipment for high-voltage testing?
Preparation involves:
- Ensuring the equipment is de-energized and properly grounded.
- Inspecting for any visible damage or wear.
- Verifying that all connections are secure and meet the test requirements.
- Consulting the equipment’s manual for specific preparation steps.
Proper preparation ensures accurate test results and maintains safety.
What is the role of tan delta testing in insulation diagnostics?
Tan delta testing measures the dielectric losses in insulation materials, providing insights into the condition and aging of the insulation. A higher tan delta value indicates increased energy dissipation, which can be a sign of insulation degradation.
