Generator Characteristics Comprehensive Testing System

I. Overview

The HD9030 Generator Characteristic Comprehensive Testing System is specifically designed for the electrical startup tests after major repairs of power generation units in power plants. It can perform real-time measurement and analysis of various characteristic curves of the generator (including no-load, short-circuit, de-magnetization, zero start, ±10% step, frequency tests, and exciter load tests, etc.), featuring a high number of measurement signals and high precision.

Section II: Technical Features

Utilizing standard interfaces to accommodate the needs of various power plants (including thermal power plants, hydropower plants, nuclear power plants, etc.).

2. The system can perform automatic data collection as well as interactive data collection.

3. Real-time plotting of characteristic curves for a more intuitive testing experience.

4. Waveform comparisons can be made, aligning measured data with historical data on the same coordinates for better judgment.

5. Our testing data is stable, precise, and reliable, enabling us to accurately assess the motor's maintenance status to ensure the generator operates smoothly.

6. Utilizing chart-based output methods for easier analysis, judgment, and archiving.

7. Utilizing an industrial control board, an integrated design with a large-screen LCD display and testing unit, offering enhanced reliability.

The system is highly programmed, significantly reducing the complexity of testing and enhancing efficiency and safety.

The 6-way voltage signal processing utilizes advanced electromagnetic induction and photoelectric isolation principles, offering high testing accuracy, rapid response time, and stable performance. The input and output are completely isolated, with isolation voltage exceeding 3KV, overload capacity up to twice the rated voltage (3-phase 150V, 3-phase 750V), and input impedance greater than 150KΩ (or 750 KΩ).

10. The 3-way current signal processing utilizes clamp-on current sensors, offering convenient and safe on-site wiring, high testing accuracy, fast response time, and stable performance. The input and output are completely isolated, with an isolation voltage greater than 3KV, and can withstand 2 times the rated overload capacity continuously, with an instantaneous overload of 20 times for 60 seconds.
