Single-Phase Digital High Current Generator

Product Introduction

Portable Intelligent High-Current Generator, controlled by dedicated digital technology and featuring a proprietary 7-inch color screen as the human-machine interface, is primarily used for primary bus protection and various current transformer ratio tests. Compared to previous-generation current-boosting devices, it employs low-power, high-capacity autotransformers and converters with high-permeability cores, offering advantages such as high output power, compact size, and lightweight design. By installing different modules, this series of equipment can perform various high-current output experiments. It is widely used in research, production, and electrical testing sites across industries such as power, railways, petrochemicals, metallurgy, and mining.

Product feature and application

3.1 Primary current, secondary current, turns ratio, polarity, and other data are displayed simultaneously on the LCD screen. When the secondary current input is disconnected or the secondary current input is ≤0.05A, the turns ratio and polarity will not be displayed to prevent infinite values from appearing and causing misjudgment.

3.2 Manual control mode operates similarly to traditional voltage adjustment methods. Current increases or decreases are controlled by manually turning the knob. The device features a zero-position detection function, enabling the "Close" button only when the voltage regulator is at zero position. The entire testing process is manually controlled and operated as needed.

3.3 High measurement accuracy: Class 0.5

3.4 Compact and lightweight design: occupies only 30%–70% of the volume of comparable products, making it highly portable.

FAQ

1)During testing of the MESQL-W82-500A high-current generator, can the operator leave the site without authorization?

Answer: No. This equipment must be monitored at all times during operation. Operators are strictly prohibited from leaving while the unit is running to address potential emergencies and ensure equipment and personnel safety.

2)Does the MESQL-W82-500A high-current generator require chassis grounding during testing?

Answer: Yes. The chassis must be reliably grounded during testing. This is a critical requirement for operator safety and stable equipment operation, preventing accidents caused by electrical leakage.

3)What usability verifications are required before reusing the MESQL-W82-500A high-current generator after prolonged disuse?

Answer: First, visually inspect the instrument for any external damage. After powering on, verify that the instrument display is functioning and showing complete readings. Additionally, check the output terminal blocks for corrosion or aging. If present, clean and restore them to good condition before use.
