Open-Loop Low-Current Tester For Excitation Systems

MOEORW-WFC63 Open-Loop Low-Current Tester for Excitation Systems

The MOEORW-WFC63 excitation system open-loop low current tester is a portable device specifically designed for excitation system testing. It integrates power supply, load, and waveform recording functions, providing accurate fault location and convenient operation. It is suitable for excitation system debugging, fault detection, and various function verifications.

The purpose of the open-loop low-current test of the excitation system is to create a simulated environment to check the basic control functions of the excitation regulator, its reliable pulse triggering capability, and the integrity of the thyristors. This includes checking whether the regulator's trigger pulses are correct and whether the thyristor power bridge can be reliably triggered. Check if the thyristor output waveform is correct.

Open-loop low-current testing of excitation systems requires an external 380V AC power supply, a resistor load with appropriate resistance and power, and a waveform recorder. To address the cumbersome preparation work for on-site open-loop testing of excitation systems, we developed an open-loop low-current tester for excitation systems, consisting of a power conversion module, a load resistor, and a display and storage device. This instrument achieves digitalization, miniaturization, and portability of open-loop testing of excitation systems.

The open-loop low-current tester for excitation systems is suitable for comprehensive testing of excitation control systems and for rapid fault location in excitation systems.

The excitation system open-loop low-current tester is suitable for the open-loop characteristics of rectifier cabinets in various models of excitation control systems. This tester is easy to operate, safe, reliable, performs well, and is easy to maintain. It can comprehensively test the phase sequence of the excitation system's synchronization signal circuit, the wiring of the pulse output circuit, the range of the control angle, the full-control bridge trigger circuit, and the working status of the main circuit, further ensuring the reliable, safe, and stable operation of the excitation system.

The open-loop low-current tester for excitation systems is suitable for fault analysis of various types of excitation systems. Faults in hardware circuits such as the measurement circuit, synchronization signal circuit, pulse circuit interference, and thyristor trigger circuit of the excitation system are typical faults in generator excitation systems. Using this open-loop characteristic tester, faults in the excitation system can be quickly located, shortening the generator downtime due to accidents.

After field use, the excitation system open-loop low current tester has eliminated the tedious work of field test preparation, greatly saved the time of excitation system open-loop test, improved the safety and reliability of field test wiring, and further reduced the labor intensity of test personnel.
