Flicker and Harmonics Testing

Thorough harmonic current testing

Testing Partners can complete harmonic testing to determine the Device Under Test’s (DUT’s) harmonic current specifications.

This test is often used in conjunction with power converters and other nonlinear loads like generators, transformers, and lamp ballasts.

During the test, we will determine the overall harmonic demand on local power supplies is minimized. We can achieve this by reducing harmonic current pull requirements, which prevents overheating and increases reliability.

Essential voltage flicker testing

Without proper testing, network lighting can be prone to flickering and reduction on consistent lighting. Electrical lights and devices can create electrical fields that arc between contacts, causing imbalances and impacting neighboring lamps.

All electrical devices and lighting systems must operate independently without negatively impacting each other. That is why Testing Partners can perform essential flicker and harmonic testing.

Establishing inrush current limits

When a device is first turned on, the voltage difference limit in EN61000-3-3 establishes the inrush current limit. This current is established when the power is on is and the product’s power source is cycled on and off 24 times. The highest and lowest registered values are discarded, and the middle 22 values are summed to obtain the final inrush current value, which is then compared to the maximum.
