HZJZ-600V Transformer TTR Calibration Verification Box

Overview

The HZJZ-600V Transformer Ratio Standard Tester, also referred to as a power frequency induction voltage divider, is a proportional conversion device composed of three interconnected transformers. By means of switch selection, the output voltage can be set to a precise ratio of the input voltage.

This instrument offers accurate voltage ratio, stable performance, and a wide range of ratios. It also features high input impedance and low output impedance, which are essential for high-precision electrical measurements. It is widely used in various sectors including electric power, testing, oil fields, railways, educational institutions, mining, and energy.

Performance Specifications:

Primary Voltage: 600V

Secondary Voltage: 0–600V

Rated Load: 0VA

Accuracy Class: 0.002

Ratio Uncertainty: 3×10⁻⁶

Weight: 10kg

Precautions For Use

1.The grounding of the instrument and the cabinet shall be reliable.

2.When in use, do not switch the range under full voltage, at least lower than 100V, and then switch.

3. If the output voltage error is found to be too large, check whether the wiring is correct, whether the fuse tube has been burned out, whether the position of the indicator panel is accurate, find out the cause and take necessary measures before retesting.

4. In order to ensure the measurement accuracy, the inductive voltage divider shall not be loaded when in use.

5. The induction voltage divider is a high-precision equipment. When verifying the induction voltage divider, pay attention to the change of the environment and do not exceed the allowable range.

6. The instrument shall be protected against shock, moisture, corrosion and cleaning.
