In the power equipment manufacturing industry, purchasing a lightning impulse voltage generator is never a simple transaction. Enterprises not only need to calculate their current procurement accounts, but also need to calculate their operational accounts for the next five to ten years. The long-term value issues of how long a device can be used after purchase, whether the upgrade cost is high, and whether maintenance is worry free are becoming the core considerations for more and more power equipment manufacturers when making decisions.
HV Hipot Electric Co., Ltd. has been deeply involved in the field of high-voltage electrical measurement for nearly 22 years. Its HVHIPOT series lightning impulse voltage generator test device is providing power equipment manufacturers with a long-term value solution from procurement to retirement through modular design, scalable architecture, and full cycle service guarantee.
Modular design: One device, multiple uses
The product lines of power equipment manufacturing enterprises often cover multiple voltage levels, from 10kV switchgear to 110kV transformers, and different products have different requirements for impulse voltage testing. If a generator is purchased for each voltage level, the cost will increase exponentially.
The lightning impulse voltage generator of Wuhan HVHIPOT adopts a 4-stage tower modular design, supporting single-stage low-voltage testing and multi-stage parallel expansion. Taking the HVHIPOT-600kV/45kJ model as an example, the equipment has a nominal voltage of ± 600kV and an energy of 45kJ. It can output standard impulse waveforms such as lightning full wave, cutoff wave, and operation wave. More importantly, its bracket, DC charging unit, etc. have scalability, which can be extended to the 1000kV level. Modular layout also facilitates installation, debugging, and maintenance, supporting flexible parameter configuration according to testing requirements.
This means that if a company purchases a 600kV device today, with product upgrades in the future, there will be no need to replace the entire machine, only adding modules can improve testing capabilities. A set of equipment can generate multiple test waveforms, suitable for impulse voltage testing of various test samples such as transformers, reactors, transformers, power cables, insulators, and bushings. This design concept of "one-time procurement, long-term adaptation" significantly reduces the cost of repeated equipment procurement for enterprises due to product line expansion.
Scalable architecture: Protecting today's investments and reserving space for tomorrow
Equipment obsolescence is the reality that enterprises are least willing to face in procurement. The essence of these problems lies in the lack of forward-looking design of the equipment, such as insufficient voltage levels, inability to upgrade functions, and inability to adapt to new technologies.
Wuhan HVHIPOT has made scalability a core design principle from the beginning of product planning. The device supports wide temperature operation from -30 ℃ to 50 ℃, and has passed environmental testing from -20 ℃ to 50 ℃. The dustproof and waterproof rating of the shell reaches IP65. In the Qinghai Tibet Plateau project, the equipment worked continuously for 12 hours without any malfunctions in a low oxygen environment. This broad environmental adaptability means that devices will not retire prematurely due to changes in usage scenarios.
In terms of functional expansion, the equipment is equipped with a Siemens PLC fully automatic control system, which supports constant current pressure regulation, automatic ball distance tracking, continuous cycle testing, and manual and automatic modes are optional. The device software supports lifelong free upgrades, ensuring that the device functions are always synchronized with industry standards. This scalable design of software and hardware collaboration allows devices to continuously evolve with industry standards and technological advancements, rather than being eliminated by the times.
Full cycle service: continuous guarantee from installation to retirement
The procurement cost is only a part of the total cost of ownership, and the expenses for later calibration, maintenance, replacement, and consumables also need to be included in the budget. Wuhan HVHIPOT has established a service system covering the entire lifecycle of equipment. The company provides lifelong maintenance. Its service network covers the whole country.
In terms of delivery efficiency, the company has efficient delivery and service capabilities, reducing the downtime from equipment procurement to production and minimizing downtime losses caused by equipment failures.
Energy saving design: reduce every operating cost
The long-term value is not only reflected in the procurement and upgrading process, but also in every kilowatt hour of electricity used in daily operations. The lightning impulse voltage generator of Wuhan HVHIPOT is equipped with dynamic load regulation technology, which can reduce energy consumption and save operating costs for users. Its patented cooling system can effectively reduce the frequency of equipment maintenance, further reducing maintenance costs. From the perspective of the entire lifecycle of the device, these detailed designs have saved users a lot of costs.
For power equipment manufacturers, purchasing lightning impulse voltage generators is not only about today's testing capabilities, but also about the development space for the next five to ten years. Wuhan HVHIPOT uses modular design to reduce duplicate procurement costs, a scalable architecture to protect early-stage investment, full cycle service to ensure long-term operation, and energy-saving design to compress daily expenses, providing the industry with a long-term value solution that can withstand the test of time. As a power engineer who has been using the equipment for a long time said, "What we buy at Wuhan HVHIPOT is not just a device, but a testing platform that can grow together with the enterprise
