Hyundai HiMAP-T Intelligent Measuring & Protection Device

The Hyundai HiMAP-T is an advanced, micro-processor-based Intelligent Measuring and Protection Device designed for comprehensive protection and monitoring of low-voltage power distribution systems. This specific “1A” model is configured for use with 1A secondary current transformers (CTs), making it highly suitable for applications where low-current precision is required or where existing infrastructure dictates a 1A standard. It provides real-time electrical data analysis and fault protection to ensure system reliability.

🏢 Application Areas

This device is a standard solution for protecting feeder circuits, motor control centers, and electrical substations in industrial facilities. By monitoring critical parameters like overcurrent, undercurrent, ground faults, and phase imbalance, it prevents damage to motors, transformers, and distribution panels. Its 1A rating makes it a frequent choice in renewable energy installations (like solar farm combiners) and utility-grade metering where specific instrument transformers are deployed.

🛠️ Product Usage Instructions

1. Safety First: Always short-circuit the CT secondary terminals before disconnecting the device. High-voltage transients can develop on open CT secondaries.

2. Mounting: Secure the device into the panel cutout using the included mounting brackets. Ensure the environmental seal is tight to maintain the device’s IP rating against dust.

3. Wiring: Connect your 1A CT inputs to the designated terminal block. Wire voltage inputs (PT) to the relay terminal block using appropriate fuses for safety.

4. Parameter Setup: Use the front keypad or the Hyundai software suite to configure your system variables: CT/PT ratios, nominal current settings, and protection trip setpoints (e.g., thermal overload, instantaneous trip).

5. Operational Check: Use a secondary current injection tester to verify the protection curves match your trip coordination requirements before putting the circuit into full service.

❓ Q&A

Why choose the 1A version over the 5A version? The 1A version is often selected for long-run wiring applications where the lower current reduces power loss in the secondary wiring, or when using specific high-accuracy 1A current transformers. What are the “Intelligent” features? Unlike standard analog relays, the HiMAP-T records event logs, stores fault waveforms, and provides digital communication of all electrical metrics (kW, kVA, power factor), allowing for predictive maintenance rather than just reactive protection. How do I integrate this into a SCADA system? The device includes an RS-485 Modbus RTU interface. By daisy-chaining the units, you can pull all real-time electrical data into a central SCADA or energy management system using standard Modbus registers. Is firmware update necessary? Firmware updates are usually only required if you are adding new communication features or resolving specific logic behavior. This is done via the dedicated communication port and a laptop.
