Сети стабилизации импеданса линии LISN / Сеть искусственной электросети AMN
Мы можем выделить три типа LISN: V-, T- и дельта-LISN
Рисунок 2. Соотношение напряжений в двухлинейной системе с раздельным заземлением.
V-LISN измеряет несимметричное напряжение помех между двумя линиями L1 и заземлением или L2 и землей соответственно.
V-LISN также называются VAN M (Искусственная сеть электроснабжения).
V-LISN, безусловно, является наиболее часто используемым LIST.
Существует два типа V-LISN с различными импедансами.
V-LISN с индуктивностью 5 мкГн (CISPR 16-1-2, CISPR 25, ISO 7637, DO160) обычно используются для измерения оборудования транспортных средств, лодок и самолетов, подключенных к бортовой сети постоянного тока частотой 400 Гц.
Другой тип V-LISN емкостью 50 мкГн в соответствии с CISPR 16-1-2, MIL STD 461 и ANSI C63.4 предназначен для работы на частотах сети 50 Гц или 60 Гц.
T-IN (рис. 2 справа) измеряет напряжение асимметричных помех (синфазное напряжение) и подает его на приемник электромагнитных помех. T-ISN обычно используется для измерения телекоммуникационного оборудования и оборудования для передачи данных, подключенного к симметричным линиям, таким как, например, витые пары..

Pilot ISN - Impedance Stabilisation Network
Pilot ISN is an impedance stabilization network which can be used to measure disturbance voltages of PLC (power line communication). Its design is based on IEC 61851-21-2 Electric vehicle conductive charging system. The ISN provides decoupling from the equipment under test (EuT) and the communication device or load (AE).
The Pilot ISN has an impedance of 150 Ω according to the standard as long as a PLC connection with an impedance of 100 Ω is established. The integrated attenuator improves the impedance matching and has to be switched on.
ECSS LISN 1
The ECSS LISN 1 was developed following the „European Cooperation for Space Standardisation“. The ECSS LISN 1 is used for DC mains lines. The impedance characteristic of each path is basically realized by an inductor in parallel with the 50 Ohm resistor: 1.5 μH || 50 Ω.
ECSS LISN 2
The ECSS LISN 2 was developed following the „European Cooperation for Space Standardisation“. The ECSS LISN 2 is used for DC mains lines. The impedance characteristic of each path is basically realized by an inductor in parallel with the 50 Ohm resistor: 2 μH || 50 Ω.
ECSS LISN 2 - 75A
The ECSS LISN 2 - 75A was developed following the „European Cooperation for Space Standardisation“. The ECSS LISN 2 - 75A is used for DC mains lines. The impedance characteristic of each path is basically realized by an inductor in parallel with the 50 Ohm resistor: 2 μH || 50 Ω.
The device under test may drain a continuous current of 75 A and for a short period of time it may even drain more than 100 A.
ECSS LISN 3
The ECSS LISN 3 was developed following the „European Cooperation for Space Standardisation“. The ECSS LISN 3 is used for DC mains lines. The impedance characteristic of each path is basically realized by an inductor in parallel with the 50 Ohm resistor: 0.7 μH || 50 Ω.
PVDC 8301 - DC-AMN (LISN)
The symmetric DC-LISN PVDC 8301 can be used for measuring the disturbance voltage in the frequency range from 0.15 MHz to 30 MHz on photovoltaic inverters.
Up to now the conducted emissions of photovoltaic inverters at the mains terminals were usually measured using LISN according to CISPR 16-1- 2. The circuit concepts of PV-inverters may cause ripple currents on the DC-side of the inverter, though. These ripple currents, which mostly are in direct proportion to the mains frequency, are passing through the cabling and the PV-generator modules and can be radiated as magnetic fields with sometimes remarkable disturbance effect. Traditional measurements at the PV-inverters' AC terminals will not be able to reveal such disturbance phenomena.
The PVDC 8301 was especially designed to measure all kinds of disturbance voltages at the DC-side of photovoltaic inverters. These are in detail the disturbance voltage of one conductor above reference ground (unsymmetrical disturbance voltage), the common mode disturbance volage of a pair of conductors above ground (asymmetrical disturbance voltage) and finally, the differential mode voltage between two conductors.

TEMP 8400 - Tempest LISN
The symmetrical AC-network TEMP 8400 consists of two identical channels for the lines "A" and "B".
It is constructed with air core inductors, in order to avoid intermodulation interference.
For the evaluation of interference phenomena the unsymmetrical interference voltage of a conductor to ground reference in the frequency range of 9 kHz to 1 GHz can be measured. Lower-frequency interference that may cause damage to the measuring receiver input shall be mitigated by additional high-pass filters.

NPLC 8500 - Line Impedance Stabilization Network
The LISN NPLC 8500 has been designed especially for PLC measurements according to ITU-T G.9901.
To determine the power spectral density of PRIME transceivers (PoweRline Intelligent Metering Evolution) the unsymmetrical voltage between a conductor and ground has to be measured within the frequency range of 3 kHz to 148 kHz.
