VLF-60KV Low Frequency Hipot Test Kit

Our next-generation 0.1Hz Ultra-Low Frequency (VLF) High Voltage Generator represents a significant leap in power testing technology. By integrating cutting-edge power electronics with high-speed ARM7 microprocessor architecture, we have achieved a breakthrough in miniaturization and reliability.

Unlike traditional mechanical boosters, which are often bulky, prone to failure, and have limited service lives, our digital VLF generator delivers stable, rock-solid performance in a compact, portable package. Its intuitive "Plug-and-Play" interface simplifies complex field operations, ensuring consistent results even in the most demanding environments.

Backed by years of field proven performance and extensive global user feedback, our 80kV VLF technology stands at the forefront of the industry, offering an unmatched balance of precision, durability, and cost-effectiveness.

Advanced 0.1Hz VLF High Voltage Generator – Key Features & Technical Advantages

1. Cutting-Edge Digital Technology

Our VLF High Voltage Generator integrates advanced digital frequency conversion technology and intelligent microcomputer control. It automates the entire testing sequence-including voltage rise (ramping), reduction, precise measurement, and multi-stage protection-ensuring laboratory-grade accuracy in field conditions.

2. Fully Automated Testing Process

Maximize efficiency with a fully automated test workflow. From initial setup to final results, the system manages the pressure adjustments and data collection autonomously, reducing the need for manual intervention and minimizing human error.

3. User-Friendly & Intuitive Operation

Designed for ease of use, the device features simplified wiring and an intuitive control interface. The User-friendly operation (Easy-to-use) allows technicians to perform complex cable insulation tests quickly and accurately with minimal training.

4. Multi-Layer Comprehensive Protection

Safety is our top priority. The instrument is equipped with multiple protection mechanisms, including over-voltage and over-current protection on both the high and low-voltage sides. With a rapid response time of ≤10ms, the system ensures immediate lockout during a fault, protecting both the operator and the equipment.

5. Enhanced Safety with Photoelectric Control

For superior operator safety, the controller is isolated from the high-voltage generator via photoelectric control technology. This ensures the low-voltage control side remains safe and reliable even during extreme high-voltage discharge events.

6. Advanced Closed-Loop Control (No Capacity Rise Effect)

By utilizing a high and low voltage closed-loop negative feedback circuit, the generator maintains a stable output. This technology eliminates the "capacity rise effect" (Ferranti effect), ensuring the actual voltage applied to the cable matches the set value perfectly.

7. Premium Configuration & Data Management

The unit is equipped with a high-definition capacitive touch screen and a clear LCD for real-time monitoring. It also features automatic data storage and an integrated printer, allowing for immediate on-site report generation.

8. Wide Frequency & Test Range

Supports multiple frequency selections, including 0.1Hz, 0.05Hz, and 0.02Hz, making it versatile for a wide range of cable insulation and power equipment testing requirements. The broad output range covers various voltage classes.

9. Portable & Lightweight Design

Optimized for outdoor operation, the generator features a compact volume and a lightweight build. This extreme portability makes it the ideal tool for field engineers performing maintenance at remote substations or wind farms.
