Page 29: Filter Performance
3.9 Filter performance Ecosine Flex Passive Harmonic Filters performance dependent on several conditions. The first condition is the size of the DC-Link choke in the drive. For 6-pulse diode rectifiers drive with ≥ 4% DC-Link choke: the typical performance achieves a THDi of 10% or better. -
Page 30: Additional Considerations Regarding The Performances
THDi performance is not guaranteed for thyristor rectifier (often called SCR drives) application. The performance of the filter is dependent on the firing angle of the thyristors. The performance can be simulated using Schaffner PQS (see section 5). 29/46 User and installation manual Ecosine Flex Passive Harmonic Filters... -

5 Performance estimation using SchaffnerPQS Ecosine Flex Passive Harmonic Filters can be simulated with the Schaffner Power Quality Simulator, SchaffnerPQS, at pqs.schaffner.com. By using SchaffnerPQS, users can easily simulate and estimate system performance, taking into account the most important design requirements and system’s boundary conditions. -
Page 34: Filter Application
6 Filter application Ecosine Flex Passive Harmonic Filters are designed to mitigate harmonic current of non-linear loads, particularly of three-phase diode-type rectifiers. Contrary to “bus-applied or PCC (Point of Common Coupling)” filters, which are being installed e.g. at the main feeder, they are specifically designed to be used with either an individual non-linear load or two of the same load connecting in parallel. -
Page 35: Filter Installation
In the case of damage, please immediately file a claim with the freight forwarder involved and contact your local Schaffner partner for support. Under no circumstances install and energize a filter with visible transportation damage. If the filter is not going to be put in service upon receipt, after inspection, store it in its original container in a clean, dry location, free of dust and chemicals and with respect to named temperature limits, see section 3.1. -

Fans are 100% field replaceable without the need to uninstall and disconnect the filter. Forced cooling devices are needed for the operation of some Schaffner Ecosine Flex Passive Harmonic Filters up to their nominal rating. Such cooling devices must be checked and cleaned regularly (if installed) to always ensure sufficient air flow. -
