Goldhome Hipot recently held a special training session for its electrical maintenance team, focusing on the correct use of digital insulation resistance testers. The training aimed to improve technicians' ability to perform accurate insulation resistance measurements using digital testing technology.
Digital insulation resistance testers offer significant advantages through their digital displays and precision measurement capabilities. During the training session, participants learned how to effectively operate these devices for routine maintenance checks and preventive electrical system assessments. The curriculum covered proper testing procedures, safety protocols, and data interpretation techniques.
Innovation in 15 kV performance with adaptive voltage control
The HM2308 sets a new standard in flexibility with a maximum adjustable output voltage of up to 15 kV, featuring step-by-step voltage selection that includes intermediate levels (e.g., 12 kV) to meet the diverse needs of equipment. This flexibility makes it ideal for testing high-voltage assets such as transformers, generators, power cables and control panels, components where accurate insulation assessment is critical to prevent downtime and safety risks.
In addition to its raw voltage capability, this tester offers laboratory-grade accuracy. It measures insulation resistance up to 35TΩ (35,000GΩ), surpassing many competitors, and automatically calculates key diagnostic metrics such as the absorption ratio (DAR) and polarisation index (PI). These values are critical for assessing insulation ageing in large-capacity equipment, facilitating proactive maintenance decisions for utility and industrial operators.
Intelligent design for harsh environments
Building on Goldhome Hipot's established tradition of robust engineering, the HM2308 features a high-strength aluminum alloy enclosure with shockproof, dustproof, and moisture-resistant construction. It operates reliably in extreme conditions: with an operating temperature range of -30°C to 60°C and relative humidity up to 85%, it is perfectly suited for outdoor substations, offshore wind farms, and mining facilities.
User-focused innovations that improve safety and efficiency:
- Dual digital/analog display: a high-definition 94.4 mm × 43.3 mm LCD screen clearly shows resistance values, voltage readings, and test status, with backlighting for low-visibility work environments.
- Automatic discharge and safety alarms: the device automatically discharges residual voltage to 0 V after testing, eliminating the risk of electric shock; an integrated alarm system warns of overvoltage or connection errors.
- Data management: The HM2308 stores up to 100 test sets and supports USB 2.0 connectivity for seamless data transfer to PCs or cloud platforms, enabling efficient compliance reporting.
Market-ready and compliant with international standards
In line with Goldhome Hipot's commitment to international standards, the HM2308 complies with IEC 61010-1 safety requirements and IEC 61326 EMC specifications, ensuring compatibility with regulations in Europe, North America and Asia. Its anti-interference technology, which includes an equipotential protection ring and a fourth-order active low-pass filter, protects measurements from electromagnetic noise in 110kV+ substations, where traditional controllers often fail.
'We designed the HM2308 to fill a gap in the market: a 15kV tester that combines portability and industrial-grade performance,' said a Goldhome Hipot product manager. 'Early adopters at China's State Grid and European renewable energy companies have praised its ability to reduce test time by 40% while providing more usable data.'
Availability and support
The HM2308 is now available worldwide, competitively priced (TBD) and backed by Goldhome Hipot's market-leading 1-year warranty. Customers benefit from 24/7 technical support, raw material traceability and customisable packaging, key services that have made the company a trusted partner in over 50 countries.
