Question 1

What is the difference between radiated emissions and conducted emissions?

Accepted Answer

Electromagnetic interference (EMI) has two types: conducted emission and radiated emission. Conducted emissions are the unintentional transfer of energy from a device through its power cord or attached signal cables. Radiated emissions are the unintentional escape of energy from equipment in the form of electric, magnetic or electromagnetic fields.

Question 2

What is the purpose of conduct emission test and radiated emission test?

Accepted Answer

The objective of conduct emission test is to measure the levels of disturbance conducted by electrical and/or electronic equipment through its power supply cables and signal lines in the frequency range from 30 kHz to 30 MHz.

The objective of radiated emission test is to measure the levels of disturbance radiated by electrical and/or electronic equipment through its enclosure and input/output cables in the frequency range from 30 MHz to 1000 MHz.

Question 3

What is Low Voltage Directive test?

Accepted Answer

LVD is the Low Voltage Directive. The goal of LVD is to ensure the safety of low voltage equipment in use. LVD covers the health and safety risks of electrical equipment operating at the following input or output voltages:

1) 50 and 1000 V AC

2) 75 and 1500V DC
