Product Description

The ZC-120A Voltage Transformer Field Tester is a specialized field testing instrument designed by our company to alleviate the heavy workload associated with the on-site verification of electromagnetic voltage transformers. This instrument is capable of accurately determining the actual error of a voltage transformer under high-voltage operating conditions by performing verification tests at low voltages. It covers the measurement of electromagnetic power voltage transformers with various transformation ratios, including 10kV/100V, 10kV/√3 /100V/√3, 35kV/100V, 35kV/√3 /100V/√3, 110kV/√3 /100V/√3, and 220kV/√3 /100V/√3. The instrument incorporates novel concepts and utilizes advanced technologies in its design—such as a "Universal Platform" technology, simulated voltage loads, an internal high-accuracy reference voltage transformer, and a self-boosting power supply—to ensure a more convenient, rapid, and efficient user experience.


Product Features:

1. The instrument features a newly added testing function for dual-winding PTs (Voltage Transformers); this allows for testing without the need for an external load box and utilizes a user-friendly touchscreen interface for operation.


2. Internally, the instrument houses a multi-ratio, self-boosting standard voltage transformer with an accuracy class of 0.05. This enables the accurate verification of errors in power voltage transformers at test voltages of 1200V and 2400V.


3. When measuring electromagnetic voltage transformers, the instrument employs a simulated load technology. This technology allows for the extrapolation of load errors under both rated load and minimum load conditions; consequently, an external voltage load box is not required during the verification process for electromagnetic voltage transformers.


4. The internal voltage transformer verifier module within the instrument possesses an accuracy class of 2.


5. The instrument features an automatic sampling function for standard-specified test points, making the process of conducting routine compliance measurements extremely convenient and rapid for the user.


6. The instrument incorporates an internal power source output and automatic voltage boosting capabilities, complemented by superior safety protection features.


7. The instrument utilizes our company's newly developed "Universal Platform" technology. This platform allows users to conveniently access useful resources—such as historical measurement data and wiring diagrams for various types of test objects—directly through the interface. It directly provides measured values, rounded values, error curves, and other data for each specific point. It automatically evaluates the measurement results, thereby further enhancing the instrument's level of intelligence.

Basic ErrorIn-phase Component: △X = ± (X × 2% + Y × 2% ± 2 digits)
Quadrature Component: △Y = ± (X × 2% + Y × 2% ± 5 digits)
“X”, “Y” — The displayed values ​​on the instrument
“5 digits” — The quantization error of the instrument

Operating RangeVoltage: (5% – 149%) Un (where Un = 100V, 150V, or 100V/√3)
Operating BurdenVoltage: a-to-x < 0.25 VA (at 100V)
Polarity IndicationDuring the first step of measurement in the Low-to-High Calibration Mode—provided the operating voltage exceeds 2V—if the “a” terminal of the Voltage Transformer Under Test (VTUT) is connected to the “x” terminal of the calibrator, and the “x” terminal of the VTUT is connected to the “a” terminal of the calibrator, the displayed error should read 200%, and a polarity error indication should appear.
Note: During testing, if the voltage exceeds 10V and no polarity error indication appears, it indicates a malfunction within the instrument itself. Please stop the test immediately to prevent damage to the instrument.
