KINGSINE KF86P Application Scenarios

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:

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).
