1 Application1.1 General1.1.1 Purposea)b)c)d)The rules in this chapter apply to electrical installations for assignment of main class. The requirementsin this chapter dealing with safety for personnel, fire and explosion hazards do apply to all types ofelectrical installations that are installed on board. The technical requirement to equipment applies even ifDNV GL product certificate or DNV GL type approval certificate is not required.The requirements dealing with availability of electrical power supply apply to electrical installationsserving essential or important services, see Sec.13.For installations of less than 100 kVA total main generator capacity, the Society may apply modified rulesfor both technical requirements and for the verification process. Modified requirements shall be agreedupon in each case and shall be made available for the operational phase.Portable electric appliances are not covered by the scope of classification.1.1.2 Supplementary requirementsSupplementary requirements will be enforced for vessels according to its ship type and additional classnotations, as required by the respective parts of the rules.1.1.3 IEC standardsa)b)The requirements in this chapter are generally based on applicable standards for ships as issued by IEC(the International Electrotechnical Commission).Where direct reference is made to such standards, it is meant the standard(s) in force at the time ofcontract between builder and owner.Guidance note:This implies primarily the IEC 60092 series for -1.1.4 Other standardsa)b)The Society will consider the use of alternative standards if they are found to represent an overall safetyconcept equivalent to that of the rules.Acceptance of the use of other standards may be given without builder’s or owner's or operator’sconsent. An application for acceptance of other standards shall be submitted. Upon request, a copy of anenglish version of the standard shall be submitted.Guidance note:Special care should be taken when requirements from different standards are used within the same --1.1.5 Alternative solutionsa)b)Alternative solutions to the requirements in the rules will be accepted by the Society when found torepresent the same level of safety and availability as the solutions required by these rules. Such anacceptance may be given without builder’s, owner's or operator's consent.Verification additional to that required by the rules may be necessary when alternative solutions areproposed. It is the obligation of the party applying for using alternative solution to ensure builder’sagreement to additional verification onboard.Rules for classification: Ships — DNVGL-RU-SHIP Pt.4 Ch.8.

2.1 General2.1.1 Work processesa)As a basis for assignment of class, the Society will verify that the electrical installation complies with therelevant rule requirements. This verification process is organised as follows:— approval of system design— equipment certification— onboard survey.b)The verification process is carried out on a spot check basis. The full responsibility for compliance withthe applicable rules lies with the builder or any other contractually bound party.c)The verification process includes requirements to approval of:— systems (including distribution systems)— equipment— components.For standard designs the case-by-case approval may be replaced by the type approval scheme.2.2 Documentation requirements2.2.1 Documentation related to system design shall be submitted as required by Table 1. Additionaldocumentation will be required if deemed necessary.Table 1 System design, documentation requirementsObjectObjectAdditional descriptionE010 - Overall single linediagramInfoAPFor:Electric powersystem, generalE050 - Single line diagrams/consumer list for switchboards— AC power systems— DC battery systemsAP— UPS systems.For:E040 - Electrical load balance— AC power systems— DC battery systemsAP— UPS systems.Rules for classification: Ships — DNVGL-RU-SHIP Pt.4 Ch.8.

Components and resolution of vectors The components of a vector are the vectors we add together to get that vector. For example, the vector shown below (in red) has many pairs of components (shown in various blues) and one pair at right angles (black). Components A Components C Components B Vector Components D (at 90 these are the most
components in electronics. Electronic components are divided into groups: Passive components Very important and essential parts but they can't amplify the voltage Electromechanical components Contains moving parts Active components Used to amplify the voltage. They are also called semiconductors. Optoelectronics components Emits or receives light
Rad-hard components: Dose 100 krad(Si) - Mrad(Si) COST components : Dose 3-30 krad(Si); some up to 100 krad(Si) The technological development of rad-hard components is 5 -7 years after COTS components. Rad-hard components are very expensive compared to COTS components. Rad-hard components may be difficult to obtain.
