ZCQG-C Power Frequency Inductive Voltage Divider: A Technical Overview

Introduction

The ZCQG-C Power Frequency Inductive Voltage Divider is a precision instrument designed for generating highly accurate and adjustable voltage ratios. Utilizing a self-coupled dual-stage voltage proportional structure with switch-selectable configurations, it enables users to achieve any desired voltage ratio with exceptional stability and linearity. This device is widely applicable in various measurement circuits and systems, offering unparalleled flexibility and precision in non-standard ratio high-accuracy measurements.

Key Features and Advantages

1.High Accuracy and Stability: The ZCQG-C achieves an accuracy class of 0.002, ensuring minimal deviation in voltage proportionality. Its dual-stage design enhances linearity and long-term stability.

2.Compact and User-Friendly: Despite its high performance, the device is lightweight (11 kg) and designed for ease of operation.

3.Non-Standard Ratio Capability: Unlike conventional dividers, the ZCQG-C supports custom voltage ratios, making it ideal for specialized measurement tasks.

4.Precision in Ratio Switching: The switch mechanism allows seamless and accurate changes to voltage ratios, reducing operational errors.

Comparative Analysis

Traditional resistive or capacitive voltage dividers often suffer from issues such as temperature dependence, frequency sensitivity, and limited accuracy. In contrast, the ZCQG-C’s inductive design offers:

1.Superior Frequency Stability: Operates optimally at 50 ± 0.5 Hz with minimal distortion (<5% input voltage distortion).

2.Reduced Environmental Impact: Maintains performance under conditions of 20 ± 5°C temperature, <80% humidity, and <1000m altitude, provided there is no strong electromagnetic interference or vibration.

3.Higher Load Tolerance: With a rated load of 0 VA, it minimizes loading effects, ensuring accurate measurements without additional compensation.

Conventional dividers typically require external calibration for non-standard ratios, whereas the ZCQG-C integrates this functionality directly, reducing setup time and potential errors.

Technical Specifications

1.Primary Voltage: 200 V (options: 400 V, 600 V, 800 V, 1000 V)

2.Secondary Voltage: 0–200 V

3.Load Capacity: 0 VA

4.Accuracy Class: 0.002

5.Power Supply Frequency: 50 ± 0.5 Hz

6.Operating Conditions: Temperature 20 ± 5°C, humidity <80%, altitude <1000 m, no strong EMI or vibration

7.Weight: 11 kg

Applications

The ZCQG-C is ideal for calibration laboratories, power system testing, and precision measurement applications where custom voltage ratios and high accuracy are critical. Its versatility makes it a preferred choice over fixed-ratio dividers in research and industrial settings.

Conclusion

The ZCQG-C Power Frequency Inductive Voltage Divider sets a new standard in voltage ratio instrumentation, combining flexibility, accuracy, and robustness. Its innovative design addresses limitations of traditional dividers, providing technicians and engineers with a reliable tool for advanced electrical measurements.
