Damped Oscillatory Wave Generator

EMCI offers a 3-phase CDN integrated unit

EMCI Plus presents a ‘Damped Oscillatory wave generator’ named DOW-CG1. The mainframe unit has an active 7-inch capacitive touch displaying the waveshape at 1.2/50 μs. The oscillator controls EUT power to a maximum of 500V DC. EUT is tested to bear the maximum current limit of up to 32 Ampere to prevent damage. This relies on a fast ethernet network.

We have acquired the accreditation of IEC/ISO 17025.

The 3-phase Coupling/Decoupling Network (CDN) makes it easier to verify the equipment's immunity to electromagnetic interference (EMC) by coupling RF directly to the equipment being tested.

According to IEC61000-4-6, this methodology is regarded as the best option for conducting tests of immunity. This allows for continuous and direct calibration, eliminating the need for any off-line inspections, which results in an improvement in both accuracy and traceability.

Special Features

  • The installed CDNs are provided to customers as an essential component of an all-inclusive immunity testing system.
  • They are compatible with any normal IEC46000-4-6 system, in addition to being usable with the RFIC-4-6 system.
  • It has the additional advantage of closed-loop control, which result in increased productivity and a decreased necessity for power amplifiers.

Control Features

DOW-CG1 works on EPOS propietary-firmware, and is equipped with 8 menu languages. It keeps you updated with the supply voltage, current and frequency on the screen.

The connectivity channel designed for a DOW test on a low-speed communication line is through the gigabit ethernet. This enables the measurement of current and voltage by converting it from analog to digital thus reducing the use of copper wires.

Usability

  • One of the most well-known problems in the field of mechanics is known as the damped harmonic oscillator.
  • Damped Oscillatory Waves in the power network get utilized at Substation IEDs, Transformers, Electricity Meters etc.
  • DOW is most reliable to assess power, control, and signal cables that are located in high-voltage and medium-voltage stations.

EMCI Plus provides high-end combined or single-function solutions for simulating slow oscillatory waves for the purpose of immunity testing on electrical and electronic equipment.
