Table of Content [Hide]

    Protection Relay Test Instrument is the core testing tool for secondary equipment in power systems, capable of performing full-functional verification of protection relay devices, automation equipment, and related power components. Below are the main product types and typical application scenarios that KINGSINE KF86P protection relay tester can test:

    KINGSINE KF86P Application Scenarios

    1. Core Testing Objects: Protection Relay Devices

    • Line Protection Devices
      Includes overcurrent protection, distance protection, pilot differential protection (e.g., fiber-optic differential, high-frequency protection), and auto-reclosing devices.
      Testing Scenarios: Simulate short-circuit faults, broken lines, power swings, etc., to verify tripping logic and time settings.

    • Transformer Protection Devices
      Differential protection (percentage restraint characteristic), over-excitation protection.
      Key Tests: Harmonic restraint characteristics, inrush current blocking function.

    • Generator/Motor Protection Devices
      Stator ground fault protection, rotor ground fault protection, loss-of-excitation protection, reverse power protection.
      Special Requirements: Must support low-frequency, high-frequency harmonics, and non-periodic component simulation.

    • Busbar Protection Devices
      Bus differential protection (current differential, composite ratio restraint), breaker failure protection.
      Key Tests: Multi-bay synchronous current injection and logic blocking verification.

    • Capacitor/Reactor Protection Devices
      Overvoltage/undervoltage protection, unbalanced current protection, harmonic overcurrent protection.



    2. Automation Equipment & Intelligent Devices

    • Automatic Transfer Switch (ATS) Devices

      Verify main/backup power switching logic, blocking conditions, and operation time (e.g., incoming line transfer, bus coupler transfer).

    • Safety Automation Devices

      Underfrequency load shedding, undervoltage islanding, stability control systems (requires synchronized multi-unit testing).

    • Smart Substation Equipment
      Merging Unit (MU), Intelligent Electronic Device (IED), Phasor Measurement Unit (PMU) protocol conformance testing (IEC 61850) (requires GOOSE/SV message support).

    • Fault Recorders

      Simulate complex fault waveforms to verify recording file integrity and time accuracy.



    3. Power Metering & Auxiliary Equipment

    • Energy Meters/Transducers
      Accuracy calibration (voltage, current, power factor), harmonic influence testing.

    • Phasor Measurement Units (PMUs)
      Dynamic signal simulation (frequency variation, phase jumps).

    • Low-Level Signal Sensors
      Simulate 4-20mA/0-5V signals for transducer testing.



    4. Renewable Energy & Special Scenario Equipment

    • PV/Wind Power Protection Devices

      Low Voltage Ride-Through (LVRT), anti-islanding protection, frequency adaptability testing.

    • DC Protection Equipment

      DC line differential protection, pole busbar protection (requires DC component output support).




    Core Advantages of the KF86P Protection Relay Test Set

    • Full Compatibility

      This substation testing equipment supports 230+ test templates for major brands (Schneider, ABB, Siemens, etc.), with pre-configured test cases and one-click automated report generation.

    • High-Precision Output

      6-phase current (6×35A) + 1-phase high current (105A), load capacity up to 424VA, covering scenarios from low-voltage distribution to high-current renewable energy applications.

    • Smart Protocol Support

      Standard support for IEC 61850 (GOOSE/SV), Modbus, and other protocols, compatible with smart grids and digital substations.

    • Multi-Functional Expansion

      Optional features include low-level signal output, harmonic superposition (up to 50th order), transient waveform simulation (e.g., oscillatory waves), meeting R&D and advanced testing needs.
