Test Equipment Description

The LI-3100 Line Impedance Stabilization Network (LISN) provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products. The LI-3100 is a 5 μH LISN compliant with RTCA DO-160, MIL-STD 461F, CISPR 25 and CISPR 16-1-2.

The LISN provides defined stable impedance and isolates the EUT from power source influences, thereby providing accurate and repeatable results. The LI-3100 includes one pair of, separately housed, single-conductor networks, to be installed in series with each current-carrying conductor in a single-phase, dual-phase or DC power system. A second LI-3100 pair can be used to accommodate 3-phase power systems (Wye or Delta configurations).

The LI-3100 is equipped with Superior Electric SUPERCON® shrouded sockets at the mains (power input) and EUT (power output) ports. The matching color-coded plugs for connection to the mains and EUT wiring are included. This LISN uses air-core inductors to prevent saturation and permeability variation. The mounting plate of the LI-3100 is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current.

Calibration

All LI-3100 LISNs are individually calibrated in compliance with the relevant requirements of RTCA DO-160, MIL-STD 461F, CISPR 25 and CISPR 16-1-2. Impedance, Phase and Insertion Loss data is supplied with each unit, along with the calibration certificate.
