Generator sets are vital as backup power in a variety of applications such as construction sites, outdoor events, mall centers and residential buildings. To ensure the safety, quality and compliance of generator sets meet international standards. JIANGSU LONGEN POWER, in collaboration with SGS, will conduct CE testing on the generator set to ensure compliance with European Union (EU) regulations and directives

1. Test sample The sample generator set for this CE test is LG-550

Prime Power: 400KW/500KVA Standby Power: 440KW/550KVA Frequency: 50Hz Voltage: 415V Engine Brand: Cummins Alternator Brand: Stamford

2. EMC Testing Generator sets are electromechanical equipment that can produce electromagnetic interference. EMC testing evaluates the ability of a generator set to operate without causing or being affected by electromagnetic interference.

2.1 Emission Test: Conducted and radiated emission testing according to standards such as EN 55012:2007+A1:2009 is an important aspect of CE testing of generator sets.

Test Method: CISPR 12:2007+A1 2009 Frequency Range: 30MHz TO 1GHz Measurement Distance: 3m Operating Environment: Temperature: 22 ℃Humidity:50% RHAtmospheric Pressure:1020 mbar Measurement Data: An initial pre-scan was performed in the chamber using the spectrum analyser in peak detection mode.Quasi-peak measurements were conducted based on the peak sweep graph.The EUT was measured by BiConiLog antenna with 2 orthogonal polarities. 2.2 Immunity Test In addition, immunity testing ensures that the generator set can withstand external electromagnetic phenomena without performance degradation. Testing according to EN 61000-6-2:2019 standards

Frequency Range: 80MHz to 1GHz, 1.4GHz to 6GHz Antenna Polarisation: Vertical and Horizontal Modulation: 1kHz,80% Amp. Mod,1% increment Results: No degradation in performance of the EUT was observed.

2.3 Electrostatic Discharge Test Discharge Impedance: 330Ω/150pF Number of Discharge: Minimum 10 times at each test point Discharge Mode: Single Discharge Discharge Period: 1 second minimum Results: No degradation in performance of the EUT was observed.

3. MD Directive Test Electrical safety testing: One of the main contents of CE testing of generator sets is electrical safety. This involves evaluating the design and construction of the generator set to ensure protection against electrical hazards. The testing process includes insulation resistance testing and other functional tests of the generator set. Compliance with standards such as EN ISO8528-13 and EN ISO12100 is critical to meeting electrical safety require ments.
