The PUSH Electrical PS-SC03 Three Phase Secondary Current Injection Kit is a cutting-edge testing solution designed for power system engineers and technicians. This device is engineered to simulate complex electrical faults and verify the performance of relays, protection systems, and microcomputer-based protection units. With its advanced technical specifications and robust design, the PS-SC03 ensures accurate and reliable testing in both laboratory and field environments. Below is a comprehensive overview of its features, capabilities, and applications.

Product Overview

The PS-SC03 is a three-phase secondary current injection kit that combines high-performance hardware and sophisticated software to deliver precise control over electrical waveforms. It is particularly suited for testing three-phase relay test kits and 3 phase secondary injection test sets, making it an essential tool for power system maintenance and quality assurance. The device’s ability to simulate a wide range of fault conditions, including transient and harmonic disturbances, ensures comprehensive testing of protection systems.

One of the standout features of the PS-SC03 is its high-performance industrial control computer, which runs the Windows operating system directly. This allows for seamless integration with modern testing software and provides a user-friendly interface for configuring test scenarios. The device also includes a 6.4-inch TFT true color LCD display, a tracking ball, and an optimized keyboard, eliminating the need for external peripherals. This design enhances usability in both controlled and remote testing environments.

The digital signal processor (DSP) microcomputer serves as the core of the PS-SC03, enabling high-speed data processing and waveform generation. The 32-bit double precision arithmetic in the software ensures that arbitrary high-accuracy waveforms can be produced for each phase. This level of precision is critical for testing complex power system scenarios, such as fault transients and harmonic distortions.

The D/A conversion and low-pass filtering components further enhance the device’s accuracy. High-precision D/A converters ensure that the current and voltage outputs maintain linearity across the entire range, while the low-pass filters eliminate high-frequency noise that could interfere with neighboring equipment. This makes the PS-SC03 ideal for environments where electromagnetic interference (EMI) is a concern.

The voltage and current amplifier system is another key feature. By using a high-performance linear amplifier output mode, the PS-SC03 can generate a wide variety of waveforms, from DC to complex harmonic combinations. This flexibility allows the device to simulate real-world fault conditions, such as short circuits, which are essential for testing relay and protection systems. The output waveforms are also smooth and clear, minimizing the risk of interference with other equipment.

The digital input and output (I/O) capabilities of the PS-SC03 include 10 channels of digital input and 8 channels of digital output. This enables the device to interface with a wide range of testing equipment and control systems. Additionally, the auxiliary DC power supply on the rear panel provides 110V and 220V outputs, offering a reliable standby power source during field tests.
