Classification of Chinese Standard F21
Classification of International Standard 27.100
Word Count Estimation 7,723

Date of Implementation 2002-12-01
Adopted Standard IEC 61334-3-22-2001, IDT
Summary This standard applies to medium voltage (MV) distribution line carrier systems (DLC) medium voltage capacitor type phase combines injection equipment and integrated inductive shielding devices. This section does not apply to non- injection type inductor combination devices. This combination device can be: a) ensure that the distribution line carrier transmission between the receiver and effectively send and receive carrier frequency signal, b) ensure personal safety and to protect the low -frequency part from high voltage and transient over- voltage. The purpose of this section is to provide medium voltage distribution line carrier systems with integrated capacitive injection equipment and integrated inductive shielding device definitions, requirements, test methods and rating.
