Westek Electronics introduces the Gridcon ACF active networked-architecture harmonic filters from MR Reinhausen designed for tough environments and offering compensation on phase and neutral conductors.
The Gridcon ACF, 400 V/690 V, three-wire and four-wire active harmonic filters offer a practical solution for improving power quality to meet Australian Standards for maximum harmonic levels at points of common coupling (pcc) and can be employed in TT, TN and IT distribution schemes. In addition to 400 volt and 690 volt models, higher line voltage models are also available.
Various cooling arrangements as well as air cooling and IP54 housing make the Gridcon ACF active harmonic filters extremely suitable for tough environments including mining applications.
Gridcon ACF active harmonic filters utilise networked architecture to offer very flexible topological control schemes and several physical plant layout options. Gridcon ACF can be integrated with industrial buses of virtually any type via its Anybus ports. The Ethernet TCP/IP interface permits control via browser.
EMC secure connections couple MIOs to the filter’s distributed synchronous controller (DSC) connecting to the IGBT converter modules. Control protocols permit sampling for example, of several MIOs depending on particular feeder correction needs. Correction schemes include neutral current harmonics compensation.
Key features of Gridcon ACF active harmonic filters:
- Modular design allows build-up of corrective harmonic power from 87 kVAr (125 amps at 400 line volts) to 348 kVAr (500 amps at 400 line volts)
- Also available for 690 line volts operation providing corrective power from 150 kVAr (125 amps) to 600 kVAr (500 amps)
- Systems can be assembled to a total of 3 MVAr corrective capacity
- Capable of handling high peak current compensation
- Very fast response (£1 ms)
- Can be configured for optimum settling times depending on application
- Harmonic correction is provided for harmonics to the 51st order
