Technical Overview of the ZCX(T)C Automatic Test Transformer Controller

The ZCX(T)C Automatic Test Transformer Controller is a specialized, microprocessor-based device designed for the automated testing and control of light test transformers. It serves as an essential piece of equipment for power supply enterprises, industrial plants (metallurgy, large factories), power generation facilities, railways, and electrical maintenance departments, offering a reliable, safe, and efficient solution for transformer testing protocols.

Core Operational Principle
At its heart, the controller utilizes advanced microelectronic processing techniques. All testing procedures are fully programmable and pre-set via the user interface. Once configured, the system executes tests automatically, requiring minimal manual intervention. This automation standardizes test sequences, reduces operator error, and enhances repeatability.

Key Technical Features & Specifications

1.Human-Machine Interface (HMI): Features a 5.7-inch backlit LCD that clearly displays real-time voltage, current, timing, and test results. The touch panel interface, complemented by direct digital key-in for ratios and settings, ensures safe, reliable, and convenient operation.

2.Automated & Programmable Control: Supports fully automatic test sequences, including automated voltage ramp-up and ramp-down. The process can be paused at any point. A built-in time relay function allows for configurable on/off conditions within a range of 1 to 9999 seconds.

3.Comprehensive Protection & Safety: Integrated over-voltage and over-current protection mechanisms enhance safety. The system is designed to automatically cut off voltage output and trigger audible/visual alarms if the high-voltage (HV) or low-voltage (LV) current exceeds preset limits. It also features automatic motor return-to-zero in case of abnormal status or undervoltage conditions.

4.Robust Performance & Flexibility: Equipped with strong anti-interference capability for stable operation in electrically noisy environments. It offers one-toggle switching between AC and DC test modes and is compatible with transformers ranging from 8 to 500 kVA.

5.Data Integrity & Connectivity: User-defined settings are stored in non-volatile memory, preserving configurations even after a power loss. The device offers options for extended functionalities such as remote communication interfaces and calibration ports.

6.Technical Indicators:

。Measurement Range: 0-9999 (digital readout)

。Accuracy: ±1.5% of Full Scale (F.S) ±2 digits

。Power Supply: AC 220V ±15%, 50Hz ±2Hz

。Build: Compact, lightweight, and durable construction for portability and longevity in demanding environments.

Conclusion
      The ZCX(T)C Automatic Test Transformer Controller represents a significant tool for technicians, integrating programmability, precise digital control, and robust safety features into a single platform. Its automated workflows not only improve testing efficiency but also ensure a high standard of safety and data consistency. The optional communication interfaces further allow for integration into broader data acquisition or control systems, making it a versatile choice for modern electrical testing applications.
