FD-1000 Multi-channel Adjustable Synchronous Amplifier for Current and Voltage Signals

New Products / New Technology

This device is a multi-channel, adjustable synchronous amplifier for current and voltage signals, developed to meet the on-site requirements of simulated loaded‑test operations at substations. It features multi‑channel detection and synchronous amplification of minute AC current or voltage signals in secondary circuits, making it suitable for synchronized simulated loaded‑test procedures across multiple bays in high‑voltage substations.

FD-100 Secondary Circuit Comprehensive Test Device

New Products / New Technology

This device is a comprehensive secondary‑circuit testing system developed to meet the on‑site requirements of simulated load‑testing at substations. It features the capability to detect and simultaneously amplify minute AC current or voltage signals in secondary circuits, as well as to perform AC impedance measurements and relay protection tests.

SVS-1200 Frequency-Variable Signal Source

New Products / New Technology

The SVS-1200 frequency‑varying signal source is designed for grid‑connection performance testing of new‑energy power plants, supporting tests such as primary frequency regulation, inertia response, and dynamic reactive power compensation. The tester features a system‑voltage‑tracking synchronization output; when operating in synchronized mode, it allows flexible setting of the output as a percentage of the system voltage and can simultaneously superimpose harmonics and intermittent waveforms, enabling comprehensive assessments of voltage ride‑through, voltage adaptability, frequency adaptability, and other critical parameters.
