Wuhan Goldhome Hipot Electrical Co., Ltd. promotes solutions for transformer oil testing
Wuhan Goldhome Hipot Electrical Co., Ltd. continues to consolidate its position in the high-voltage testing equipment market by focusing on the development of instruments for evaluating the quality of insulating oils. The company is responding to the power industry's demand for accurate monitoring of the condition of electrical installations through its expertise in developing reliable testing instruments, including equipment for measuring dielectric loss and volume resistance.
The Importance of Dual Parameters: The Foundation of Insulation Performance
The tangent of the loss angle (tanδ) and volume resistance (ρv) are used as fundamental indicators to evaluate the electrical breakdown resistance of insulating oil and its capacity to minimize energy loss. A high tanδ value indicates that the oil converts excessive energy into heat and accelerates the aging of the transformer. Conversely, low volume resistance indicates insufficient insulation strength and increases the risk of short circuits. Traditional tests require separate equipment for each parameter, resulting in time-consuming workflows, high costs, and inconsistent data. Goldhome Hipot's integrated test device eliminates these challenges by enabling simultaneous multi-parameter analysis, which is crucial for the proactive maintenance and quality control of insulation oil in transformers, capacitors, and other high-voltage equipment.
Key benefits: Accuracy, efficiency, and integration
The Goldhome Hipot dielectric loss and volume resistance tester sets new standards with its advanced features:
Dual testing capability: A single test simultaneously measures dielectric loss (tanδ, 0.0001–1.0) and volume resistivity (ρv, 10⁶–10¹⁴ Ω·cm) in accordance with GB/T 5654, IEC 60247, and ASTM D924. The measurement error is ≤±0.5% for tanδ and ≤±10% for ρv, ensuring reliable and traceable results.
Fully automated operation: Users only need to insert a 50 ml oil sample. The controller automatically checks the temperature (30 °C/40 °C/50 °C/90 °C, adjustable), applies the test voltage (1 kV–5 kV) and calculates both parameters, eliminating manual intervention, reducing human error and cutting testing time by 50% compared to separate devices.
High temperature stability: It features a precision heating system with a temperature fluctuation of ±0.1 °C and a hermetically sealed test cell that ensures accurate results even at high test temperatures (e.g., 90 °C for accelerated aging analysis).
Intelligent data management: Equipped with a 7-inch color touch screen, the device displays tanδ/ρv values in real time, temperature curves, and test reports. It stores up to 3,000 historical records and supports data transfer via USB/network, integrating seamlessly with laboratory information systems (LIMS) for data monitoring and compliance reporting.
User-friendly design for industrial versatility
Designed for successful operation in a variety of industrial environments, this tester offers unmatched convenience and durability:
Wide range of applications: suitable for mineral oil, synthetic oil, natural ester oil and other insulating oils; meets the quality control requirements of transformer manufacturing, transformer station maintenance and petroleum refineries.
Compact and portable: Weighing only 12 kg, the modular design is suitable for both laboratory use and on-site testing at remote transformer stations; no need for bulky, separate equipment or sample transport.
Low maintenance: The test cell is made of corrosion-resistant materials (PTFE + stainless steel) with a self-cleaning function, which facilitates maintenance. Automatic calibration reminders and built-in diagnostic tools ensure long-term, stable performance.
