Fast transients caused by electrical switches, relays and motors, fluorescent lamp ballasts.Electromagnetic surges due to a lightning strike.Magnetic fields, like the ones radiating from electrical wires.Electrostatic discharges associated with static electricity.Electromagnetic phenomena that is replicated through EMC testing includes: The EMC testing routine depends on the nature of the device being tested, its intended application and the regulatory requirements for its use. ICNIRP Guidelines limiting exposure to time-varying electric, magnetic and EM Fields(up to 300GHz).IEEE C95.1 Standard for safety levels with respect to human exposure to radio frequency electromagnetic fields.Malfunction of critical process control functions(ex.Malfunction of automotive microprocessor control system(braking) and navigation equipment.Malfunction of Medical electronic equipment.

Interference to TV and radio reception.Loss of data in digital systems or in the transmission of data.What is EMC (Electro Magnetic Compatibility)?ĮMC: EMC is defined as the ability of electronic and communication equipment to be able to operate satisfactorily in the presence of interference and not be a source of interference to nearby equipment. The resulting Electromagnetic Interference (EMI) can affect aircraft navigation, communication and control systems.Īfter electrical, electronics, and photometry, ITC India Pvt Ltd has spread its wings in EMC testing. This is because Cell phones, as well as other personal electronic devices such as laptops, tabs etc, emit signals from High-Frequency clock oscillators. Even, You are requested to switch off your mobile phones or change to Airplane mode while traveling by plane. They found a passenger was using a Laptop.
On a flight, during takeoff captain observe interference on Navigation System. Limitation of voltage changes, voltage fluctuations, and flicker Limits for harmonic current emissions (equipment input current =16 A per phase) Voltage dips, short interruptions and voltage variations immunity tests We can do the following EMC testing on your product.Įlectrostatic discharge immunity test(ESD test)Įlectrical fast transient/burst immunity test We focus on the following industries product EMC/EMI testing: EMI EMC testing is now a prerequisite testing for all product designers making new products.
