GDYD-P-250/50 Portable Hipot Tester | HV HIPOT’s New Solution for Field HV Testing

HV HIPOT ELECTRIC CO., LTD., a leading global manufacturer of IEC & CE certified high-voltage (HV) test and measurement solutions, today announced the official launch of its upgraded GDYD-P-250/50 Programmable AC/DC Hipot Test Set, alongside the successful completion of on-site commissioning and acceptance for a 30MW ground-mounted solar PV project in Batangas, Philippines. This milestone validates the product’s industry-leading portability, stability, and testing efficiency in complex field environments, while strengthening HV HIPOT’s presence in Southeast Asia’s fast-growing renewable energy market.

AC/DC hipot testing is the industry-standard method to verify insulation integrity of HV electrical assets, a critical step to ensure operational safety, prevent electrical failures, and comply with global grid standards. Traditional hipot testers often suffer from bulky structures, complex operation, and poor adaptability to harsh outdoor environments—key pain points for on-site maintenance teams in solar PV, power distribution, and industrial electrical sectors. The GDYD-P-250/50 is engineered to address these challenges, with a portable, user-centric design tailored for both field on-site testing and factory acceptance tests (FAT).

Core Specifications & Key Advantages of the GDYD-P-250/50 AC/DC Hipot Test Set:

Precision Output: Rated capacity 250VA, with continuously adjustable AC 0-50kV RMS and DC 0-50kV output, voltage accuracy ≤1.5% F.S, fully compliant with IEC 60060, IEC 61010-1 international standards and CE certified.

Portable & Rugged Design: Integrated dry-type HV test transformer with a wheel-mounted, compact structure, 30% lighter than conventional models, enabling single-person transport and operation in narrow field working spaces. IP54 dustproof and waterproof enclosure ensures stable operation in -20°C to 50°C extreme environments, perfectly adapting to Southeast Asia’s high-temperature and high-humidity conditions.

Intelligent Programmable Control: Full keyboard operation with high-resolution LED display, supporting automatic voltage ramp-up, timing test, and voltage ramp-down. Built-in 0-9999s programmable timer, with automatic data storage, USB data export, and IEC-standard test report generation functions.

Multi-Layer Safety Protection: Equipped with zero-position start interlock, over-voltage, over-current, short-circuit protection, and sound-light alarm functions, minimizing operational risks and ensuring operator safety during high-voltage testing.

The 30MW solar PV project in Batangas, developed by Solar Philippines, one of the country’s largest renewable energy developers, required comprehensive insulation withstand testing for over 12,000 PV modules, 32 pad-mounted transformers, 45km of HV power cables, and inverter equipment. The project team set strict requirements: test equipment must comply with Philippine grid codes and IEC standards, adapt to outdoor high-temperature and high-humidity environments, and deliver high testing efficiency to meet tight grid connection deadlines. After a rigorous technical evaluation, the GDYD-P-250/50 was selected as the core test solution for the project, beating 8 competing international brands.

During on-site implementation, HV HIPOT’s Southeast Asia localized service team provided full-cycle support, including pre-sales test scheme design, on-site operation training, and 24/7 technical consultation. The customer’s engineering team completed all insulation withstand tests for the project 7 days ahead of schedule, with testing efficiency improved by 50% compared with traditional equipment. All test items passed the owner’s and local grid’s strict acceptance criteria at one time, with the equipment maintaining continuous and stable operation throughout the 3-week testing period in 35°C+ high-temperature and high-humidity outdoor conditions.

“The GDYD-P-250/50 has completely exceeded our expectations,” said the project engineering manager of Solar Philippines. “Its portability allows us to move quickly between different test points in the PV plant, and the programmable function greatly simplifies our workflow. Even in harsh outdoor conditions, the test data remains accurate and stable, and HV HIPOT’s localized service support has been exceptional throughout the project.”

The GDYD-P-250/50 AC/DC Hipot Test Set is now available for global order, with customized configurations available to meet specific project requirements. HV HIPOT provides full-cycle technical support for all customers, including on-site commissioning, operation training, and lifetime after-sales service.
