What is the YD(J.Z) Series Power Frequency Withstand Voltage Test Equipment?
The YD(J.Z) Series Power Frequency Withstand Voltage Test Equipment is a critical apparatus for evaluating the insulation integrity of electrical products, power equipment, and insulating materials. Widely adopted by power plants, distribution systems, and research institutions, this equipment subjects test objects to specified high voltages to identify insulation defects and assess overvoltage tolerance. Its robust design and advanced technical specifications make it indispensable for compliance testing and quality assurance in high-voltage environments.
Key Features and Advantages
1.Superior Material Selection: Built with high-quality components, the YD(J.Z) series ensures exceptional stability and durability.
2.Optimized Voltage Performance: The equipment minimizes corona discharge and partial discharge phenomena, even under high voltage stress, thanks to its large voltage margin.
3.Compact and Lightweight: Utilizing modern insulation materials, the system achieves a reduced footprint and weight without compromising performance, enhancing portability for field applications.
Technical Comparisons Across Models
The YD(J.Z) series offers a wide range of configurations to meet diverse testing requirements. Below is a comparative analysis of key models:
Model | Capacity (kVA) | High Voltage (kV) | High Current (mA) | Low Voltage Input | Transformation Ratio |
1.5/50 | 1.5 | 50 | 30 | 200V, 7.5A | 500 |
10/50 | 10 | 50 | 200 | 200V, 50A | 500 |
15/50 | 15 | 50 | 200 | 380V, 79A | 1000 |
50/100 | 50 | 100 | 500 | 380V, 130A | 1000 |
100/150 | 100 | 150 | 667 | 380V, 263A | 1000 |
300/200 | 300 | 200 | 1500 | 400V, 750A | 1000 |
Key Observations:
1.Capacity vs. Voltage: Lower-capacity models (e.g., 1.5–50 kVA) suit small-scale tests (≤50 kV), while high-capacity units (100–300 kVA) support ultra-high voltages (150–300 kV) for large infrastructure.
2.Input Flexibility: Models below 15 kVA use 200V input, whereas higher-capacity units operate on 380–400V, aligning with industrial power standards.
3.Current Scalability: High-voltage current scales proportionally with capacity—e.g., the 300/200 model delivers 1500 mA, ideal for heavy-duty applications.
4.Transformation Ratio: Most models maintain a 500–1000 ratio, ensuring precise voltage regulation. Exceptions like the 25/150 (ratio 1500) cater to specialized voltage amplification needs.
Design Consistency
All models share a uniform temperature rise limit of ≤10°C after 30 minutes of operation, reflecting efficient thermal management. The use of standardized insulation materials ensures reliability across the series.
Applications
1.Low-Capacity Models (1.5–10 kVA): Ideal for testing household appliances, small transformers, or laboratory samples.
2.Mid-Range Models (15–50 kVA): Suited for medium-voltage switchgear, cables, and industrial equipment.
3.High-Capacity Models (100–300 kVA): Designed for power transformers, GIS systems, and utility-scale infrastructure.
The YD(J.Z) series distinguishes itself through modular scalability, precision engineering, and adaptability to global voltage standards. By offering configurations from compact 1.5 kVA units to heavy-duty 300 kVA systems, it addresses a broad spectrum of insulation testing challenges. Its optimized balance of portability, safety, and performance positions it as a benchmark in high-voltage test equipment for both routine diagnostics and rigorous industrial applications.
