ABB 3BHE027632R0101 High Voltage Inverter Spare Parts
Planning the electrical installationChapter overview
This chapter contains the instructions that must be followed when selecting the motor, cables, protections,
cable routing and way of operation for the drive system. Always follow local regulations. This chapter applies to
all DCS880 converter modules.
Attention:
If the recommendations given by ABB are not followed, the drive may experience problems not covered by
warranty. See also Technical guide.

Line reactors (L1)
For armature and field supply.
When thyristor converters operate, the line voltage is short-circuited during commutation from one thyristor to
the next. This operation causes voltage dips in the mains PCC (point of common coupling). For the connection
of a power converter system to the mains, one of the following configurations applies:
Configuration A
When using a converter, a minimum of impedance is required to ensure proper performance of
the snubber circuit. Use a line reactor to meet this minimum impedance requirement. The value
must therefore not drop below 1 % uk (relative impedance voltage). It should not exceed 10 % uk,
due to considerable voltage drops at the converters outputs.
Configuration B
If special requirements have to be met at the PCC (standards like EN 61 800-3, DC and AC drives
at the same line, etc), different criteria must be applied for selecting a line reactor. These
requirements are often defined as a voltage dip in percent of the nominal supply voltage. The
combined impedance of ZLine and ZL1 constitute the total series impedance of the installation.
The ratio between the line impedance and the line reactor impedance determines the voltage dip
at the PCC. In such cases, line chokes with an impedance around 4 % are often used.
Example calculation with ukLine = 1 % and ukL1 = 4 %:
Voltage dip = ZLine / (ZLine + ZL1) = 20 %. Detailed calculations see Technical guide.
Configuration C
If a dedicated transformer / isolation transformer is used, it is possible to comply with certain
connecting conditions per Configuration B without using an additional line reactor. The
condition described in Configuration A will then likewise be satisfied, since the uk is > 1 %.

Configuration C1
If 2 or more converters should be supplied by one transformer the final
configuration depends on the number of drives in use and their power capability.
Configuration A or B has to be used, if the drive system consists of any of the
converters H1, H2, H3, H4, H5, H6, H7, H8.
In case if only two converters of type H8 are used no line reactors are necessary
because the design of these converters allows that configuration.
Configuration D
In the case of thyristor converters, frequently transformers are used for voltage matching. When
using an autotransformer for this purpose, additionally install a line reactor, because the uk of
commonly used autotransformers is too small.
In case of converters size H1 ... H5 the allowed voltage at the PCC is
Line reactors for converters
The line reactors listed in table below
– have been sized to the units nominal current and frequency (50 / 60 Hz)
– are independent of converter's voltage classification; at some converter types the same line choke is used up
to 690 V line voltage
– are based on a duty cycle
– can be used for DCS880 as armature converter as well as field converter, but rated line choke current must be
considered.
