Revolutionary Lightweight Solution for Protection Testing: KFA310 Field Advantages

In an industry where traditional protection relay test equipment is often bulky and complex to operate, the Kingsine KFA310 introduces a revolutionary design that redefines field testing. Weighing only 3.7kg with a compact, iPad-sized form factor, it transforms mobility in relay protection testing.

Core Advantages of Lightweight Design

1.Unmatched Portability

• Built-in high-density lithium battery supports 8+ hours of continuous operation, eliminating reliance on fixed power sources—ideal for substations, transmission towers, and remote field sites.

• All-in-one waterproof carry bag integrates test leads, tools, and the host device for true "grab-and-go" convenience.

• Ergonomic one-hand carry design adapts to challenging environments (e.g., tower climbing, tunnel inspections).

2.Breakthrough Field Efficiency

• Ready-to-test in ≤3 minutes with instant startup.

• Pre-saved test profiles enable rapid deployment of recurring test plans.

• Glove-friendly touchscreen ensures reliable operation in harsh conditions.

3.Dramatically Reduced Maintenance Costs

• Modular design allows key component replacement in ≤20 minutes.

• Plug-and-play architecture eliminates recalibration, cutting maintenance costs by 70%.

Reliability by Design

1.Structural Innovation

• Minimalist circuitry with core components consolidated on 3 PCBs, enabling 3-step assembly:
  (1) Install voltage amplifier, (2) install current amplifier, (3) mount touchscreen.

• Fully sealed metal enclosure validated through rigorous aging, thermal, and environmental tests.

2.Intelligent Protection Mechanisms

• Triple-safeguarded outputs: overcurrent/overvoltage/short-circuit protection.

• Advanced battery management system (overcharge/over-discharge/temperature protection).

Redefining Field Testing Standards

The KFA310’s lightweight philosophy transcends hardware—it upgrades workflows:

• Labor savings: Replaces 2–3-person crews with single-operator testing.

• Space adaptability: Deploys directly in confined spaces (cable trenches, RMUs).

• Efficiency + safety: Minimizes equipment transport risks and temporary wiring hazards.

From substation maintenance to field tower commissioning, this 3.7kg test set proves that professional-grade performance and extreme portability are not mutually exclusive. Its design ethos addresses the core demand of field engineers: carrying lighter loads to shoulder greater responsibilities.
