IEEE 45.6-2016 pdf free.IEEE Recommended Practice for Electrical Installations on Shipboard- Electrical Testing.
Occupational Safety and Health Administration (OSHA) regulations and the National Fire Protection Association (NFPA) 70E® Standard for Electrical Safety in the Workplace® [Bi 1112 provide the requirements for the safe use of test equipment. For example, NFPA 70E 110.4 states. Only qualified persons shall perftrm tasks such as testing, troubleshooting. and voltage measuring within the limited approach boundary of energized electrical conductors or circuit parts operating at 50 volts or more or where an electrical hazard exists.” OSHA 1910.333(b)(2)(iv)(B) [B 13] states, ‘A qualified person shall use test equipment to test the circuit elements and electrical parts of equipment to which employees will be exposed and shall verify that the circuit elements and equipment parts are deenergized.” IEEE Std 45.5-2014 [B7j, along with ANSI S82.02 LB 1J, CAN/ CSA-C22.2 [B2], IEC 60204-I [B 3], 60204-11 [B4j, and JEC 61010 [B5] also provide important safety rules for the use of electrical test equipment.
After the electric installation is complete, the entire electric plant should be thoroughly inspected and tested at the dock prior to proceeding to sea trails. Tests are intended to determine general equipment condition and to confirm that the installation of electrical systems and equipment is in a satisfactory and acceptable state at the time of completion. These tests should be in addition to, and not as a substitute for, the tests of individual equipment items at the manufacturer’s facility (factory acceptance test). The contingent engineering team needs to realize that satisfactory test results, although providing worthwhile information on general equipment condition, do not always confirm that any particular installation is satisfactory in all respects nor do they validate that installation interconnections are correct. Therefore, the commissioning team needs to make certain that each installation and interconnection has been adequately tested in all operational configurations.
The initial inspection, which may consist of a series of inspections during the construction of the vessel, should include a complete inspection of the electrical installation and electrical equipment. The inspection should confirm that the electrical arrangement. materials, power and control cable connections, and installations fully comply with the component and ship/vessel design documents. The inspection should also confirm that equipment and installations arc correct and meet all imposed quality standards.
Electric cable should be checked during installation to confirm it is the size and type shown on the plans. The adequacy of cable supports should be checked. It should be ascertained that no cable is installed in the proximity of steam pipes or other hot objects and that cables have not been damaged during the installation from excessive pulling force, over bending, or sharprough edges. Cable penetrations required to be watertight should he checked for proper penetrator packing, terminal, or stu fling tube.IEEE 45.6 pdf free download.
