Friest – Strumentazione per misure CEM, Strumentazione EMC e Filtri RF
The task of the described laboratory test is to find the reaction of the equipment under test EUT under specified operational conditions to surge voltages caused by switching and lightning effects. The publication defines the immunity test requirements for equipment within its scope in relation to continuous and transient conducted and radiated disturbances, including electrostatic discharges ESD.
However, in the frequency range from kHz up to approximately 10 MHz protection from both, low frequency effects on the nervous system as well as high frequency effects need to be considered depending on exposure conditions.
These structures can be further classified as one- two- or multi-port TEM waveguides.
This standard applies to apparatus intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source which is intended to interface between the apparatus and the low-voltage public mains network. Aiutaci ad esserti d’aiuto!
The test method documented in this standard describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. It is applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low voltage distribution systems.
They are in addition to the requirements of the general standard IEC and serve as the basis for particular standards. This fifth edition of CISPR 11 got a more transparent structure, introduces another set of particular limits for conducted and radiated disturbances of ‘heavy duty’ general purpose equipment of class A group 1 with a rated input power in excess of 20 kVA, in accordance with the needs of the industries and refers to the full approach in respect of the measurement instrumentation uncertainty specified in CISPR 16 4 4.
Characteristics, performance and verification of the test generator and related inductive coils are revised. It establishes a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to harmonics and inter-harmonics and mains signalling frequencies. Guidelines applicable to movement-induced electric fields or time-varying mag- netic fields up to 1 Hz will be published separately.
This third edition cancels and replaces the second edition published inand its Amendments 1 and 2 Immunity requirements in the frequency range 0 Hz to GHz are covered.
This part of CISPR 16 is designated a basic standard, which specifies the characteristics and calibration of the absorbing clamp for the cdi of radio disturbance power in the frequency range 30 MHz to 1 GHz. This generic EMC emission standard is applicable if no relevant dedicated product or product-family EMC emission standard exists.
The csi do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. This second edition cancels and replaces the first edition published in and its amendment 1 Has the status of a Basic EMC publication. Relates to the immunity requirements of equipment, only under operational conditions, to pulse magnetic disturbances mainly related to: Tali informazioni riguardano essenzialmente: Other distribution systems are excluded.
Guaranty of drying up As soon as the device will be installed, one of our technician will periodically come to control it to make sure it is correctly functioning. The object of IEC This third edition cancels and replaces the second edition published inand constitutes a technical revision which includes the following significant technical changes with respect to 211- previous edition: Covers all measuring relays and protection equipment used for protection within the power 211-6 environment.

The effects of electromagnetic phenomena relating to the safety of apparatus are excluded from the scope of this standard. This standard applies to equipment intended to be connected to low-voltage systems interfacing with the public supply at the low-voltage level.
In addition, requirements are provided for specialized equipment for discontinuous disturbance measurements. The receiver types to be protected are, for example, broadcast receivers sound and televisionland mobile radio, radio telephone, amateur, citizens’ radio, Satellite Navigation GPS, etc.
This new edition includes the following significant technical changes with respect to the previous edition: Only a complete vehicle test can be used to determine the component compatibility with respect to a vehicle’s limit.
No measurement needs to be performed at frequencies where no requirement is specified. For the purpose of this document, the low-frequency range extends from 1 Hz to kHz. Deals with the electromagnetic immunity of appliances and similar apparatus for household and similar purposes that use electricity, as well as electric toys and electric tools, the rated voltage of the apparatus being not more than V for single-phase cdi to be connected to phase and neutral, and V for other apparatus.
The test requirements are specified for each port considered.
