Standard Evolution and Technology Upgrade
Technical Dimension 1998 Edition 2024 Edition Upgrade Points Frequency Range Below 1 GHz Extended to 6 GHz Added 1-6 GHz radiated emission requirements Port Classification Category 4 Port Category 6 Port New Communication Port, Shell Port Test Method Phenomenon Simulation Port directional test Newly added ring wave and pulse magnetic field tests
Core parameter interpretation
Power supply technical requirements
Power supply type Key indicators Tolerance requirements AC power supply 220V/380V AC3 level (±20%) DC power supply 220V/110V DC3 level (±15%)
Key points for electromagnetic compatibility implementation
Typical test configuration example
For distribution automation terminals, the following tests are required:
- Level B radiated emission test (30MHz-1GHz)
- 4kV electrostatic discharge (contact/air discharge)
- 10V/m RF field immunity (80MHz-1GHz)
Communication ports need to additionally meet the conducted emission limit: 74dBμV@0.5MHz
Comparative analysis of the new and old standards
Major technical changes
- Delete 14 old terms, add 12 definitions such as maximum internal frequency
- AC voltage nominal value adjustment: 380V replaces the original 400V three-phase voltage
- Electrical fast transient pulse group test frequency increased from 5kHz to 100kHz
Engineering application suggestions
Equipment selection guide
Application scenarios Power supply requirements EMC level Substation control room AC2 level + H1 harmonics Level A Distribution network FTU terminal DC2 level + VR3 ripple Level B Note: For equipment containing power carrier communication, special attention should be paid to the radiated immunity in the 1.4-2.7GHz frequency band
