This 3 Phase Relay Test Equipment delivers standard 4-phase voltage and 3-phase current output, enabling flexible combinations for protection testing across relay types. Single-phase voltage reaches 120V, while single-phase current outputs up to 40A for 10 seconds, with three-phase current scalable to 120A. The fourth phase voltage (Ux) serves as a multi-function item, configurable for 3U0 variants, same-period voltage checks, or fixed voltage outputs, providing versatility for complex fault simulations.
The unit integrates a large 320x240 LCD with Chinese-language interface, operated via a rotating mouse for intuitive control in field conditions. It supports verification of traditional relays, microcomputer protections, and transient or permanent fault simulations, with dual operation modes: standalone for basic tasks or PC-connected via Windows software for automated, high-complexity testing. The software enables real-time data storage, vector diagrams, fault waveform plotting, and online report printing, streamlining large-scale verification work such as three-phase differential or line protection inspections.
Designed for electrical testing professionals, this equipment suits utilities, substations, and industrial plants requiring precise relay calibration and protection system validation. Its self-protection features include heat dissipation design, power soft-start, and fault self-diagnosis, while dedicated DC outputs (110V and 220V) support auxiliary testing needs. The device’s cost-performance ratio reflects its cross-professional design, balancing advanced functionality with accessible pricing for mid-tier testing applications.

Before ordering, verify the tester’s compatibility with your specific relay types and protection schemes. Confirm whether the 4-phase voltage and 3-phase current outputs align with your testing requirements, as some applications may demand higher current or voltage ranges. Request a demonstration of the software’s automation capabilities, particularly for complex fault simulations and data logging.
Clarify logistics details, including lead time, Incoterms (e.g., FOB Wuhan), and packaging for international shipment. The tester’s weight and dimensions (not specified) should be confirmed to ensure compatibility with your facility’s handling equipment. Payment terms, such as TT or LC, and any applicable certifications for import (e.g., CE, ISO) must also be discussed with the supplier.
Inspect the unit upon arrival for compliance with the listed specifications, particularly the LCD display, current/voltage ranges, and switch contact configurations. Test the self-protection features, such as fault self-diagnosis, to ensure operational safety. Request calibration certificates and user manuals in your preferred language, and confirm the availability of technical support for installation and training.
