EMC: AUTOMOTIVE TESTING


❱❱ The size of the anechoic chamber at JIAT makes it suitable for a range of test subjects, including large commercial


vehicles, while powerline EMC/EMP filters, inset, of up to 100A protect the facility at the Korean automotive proving ground


Korea scales up its vehicle testing ability


Facilities such as the large anechoic test chamber supplied by MPE are adding strength to the Korean automotive industry


M


otor vehicle manufacturing in South Korea has established itself as a top player in the global automotive market and in recent years has been


catching up in innovation, development and testing expertise. The Jeonbuk Institute of Automotive


Technology (JIAT) in Gunsan, a city in the North Jeolla province in the south west of the country is a centre of automotive expertise, which takes a clustered approach to development, testing and technology assessment for the industry. JIAT was established in 2003 as a


government test organisation providing assessment services of vehicles and their systems and components in order to help research and development by small and medium-sized enterprises (SMEs) that do not have a test facility of their own. Now, it provides consulting, research and training services in a facility of over 33,000m2 Such large automotive manufacturers as


.


Hyundai and GM Daewoo have their own, exclusively operated test facilities and proving grounds. The General Motors


Gheongna proving ground is a privately owned test track, engineering centre and test house that occupies a staggering 477,000m2


from these, the JIAT is the biggest automotive test house in South Korea.


LARGE ANECHOIC CHAMBER One of the more recent additions to the JIAT portfolio of test equipment is a large anechoic test chamber, which is used for EMC, NVH (noise, vibration and harshness) and performance testing as well as hardware-in-the-loop (HIL) simulation. To achieve this, local specialist company


Eretec provided a screened room test chamber, which included EMC shielding, doors and filters as well as all internal equipment systems such as absorbers, turntable and dynamometer. The equipment used in the chamber


included 12 MPE powerline filters that were specified and installed and which comprise five different models from MPE’s catalogue range rated at 16A, 32A, 63A and 100A. The specification and size of the

chamber enables it to have multiple purposes across a wide range of vehicles. The built-in dynamometer is capable of handling large commercial vehicles as well as standard passenger cars.


FROM DEFENCE TO TEST HOUSES Commenting on the organisation’s choice of EMC filtration systems, Paul Currie, director at MPE, says the company is the prime supplier of EMC/EMP filters within the Korean defence industry and is also doing well in the commercial sector, such as the application at JIAT. “MPE were delighted that JIAT chose


and installed MPE’s high-performance filters within its flagship test chamber and this installation is further evidence of MPE’s growth into the commercial sector within Korea,” he says. He went on to say that the competition


is strong in the local market so the role of MPE’s partner, Eretec, has proven crucial in developing this and other client relationships and given the visible pipeline of future projects that MPE could branch into in the future in this territory. T&TH
