5KVA/50KV AC/DC Power Frequency Withstand Voltage Test Set
Industrial-Grade High-Voltage Testing Solution for Electrical Equipment & Insulation Validation
Product Overview
The 5KVA/50KV AC/DC Power Frequency Withstand Voltage Test Set is a professional-grade high-voltage testing system designed for rigorous insulation strength evaluation of electrical equipment, components, and insulating materials. Comprising a precision control box and an oil-immersed test transformer, this system delivers stable, accurate, and safe high-voltage output for both AC and DC withstand tests. Engineered for industrial and laboratory use, it meets international safety standards and is ideal for quality assurance, R&D, and maintenance in power systems, manufacturing, and research institutions.
Key Features & Engineering Advantages
-
Dual AC/DC Output Capability
- Supports both alternating current (AC) and direct current (DC) high-voltage testing modes.
- DC output voltage is 1.4 times the AC RMS voltage, enabling comprehensive insulation stress analysis under different conditions.
-
High-Precision Control & Measurement
- Equipped with a digital control panel featuring real-time monitoring of voltage, current, and test duration.
- Voltage regulation via a smooth-rotation variac ensures stepless, precise voltage adjustment from 0 to 50kV AC / 70kV DC.
-
Comprehensive Safety Protection System
- Integrated overcurrent, zero-start, and emergency stop protection to prevent equipment damage and ensure operator safety.
- Audible and visual alarms activate upon fault detection or test completion.
-
Robust & Portable Design
- The oil-immersed transformer uses high-quality polyester漆包线 and premium insulating oil for superior dielectric strength and thermal stability.
- Compact and lightweight (65kg for the 5KVA unit), with a durable metal enclosure and integrated handles for easy transport.
-
Versatile Application Scope
- Suitable for testing transformers, circuit breakers, cables, bushings, insulators, and other high-voltage apparatus.
- Can be configured with optional accessories like discharge rods, protective sphere gaps, and HV digital voltmeters for advanced testing setups.
