Electrical Safety 

Managing Electrical Risks in The Workplace - Code of Practice - This Code provides practical guidance for persons conducting a business or undertaking on managing electrical risks in the workplace. It applies to all workplaces where a person conducting a business or undertaking has management or control of electrical equipment, including electrical installations, or carries out electrical work on or near energised electrical equipment, including electrical installations - from Safework Australia.

Department of Energy  Handbook on Electrical Safety – The Electrical Safety Handbook presents the Department of Energy (DOE) safety standards for DOE field offices or facilities involved in the use of electrical energy. It has been prepared to provide a uniform set of electrical safety guidance and information for DOE installations to effect a reduction or elimination of risks associated with the use of electrical energy. The objectives of this handbook are to enhance electrical safety awareness and mitigate electrical hazards to employees, the public, and the environment. It has a section on working with test instruments and equipment.

Inspection and Testing of Electrical Equipment 

Testing Manual for Electrical Equipment - Nahed Al-Hajeri and Anantha Madhavan - The purpose of this testing manual is to provide guidelines for inspection and testing of Electrical Equipment in compliance to relevant international standards/specifications. It provides information on procedures and testing of Major Electrical equipment to be followed during testing by engineers and also furnish evidence that an electrical equipment/device is free of inherent flaws or faults. The tests on equipment/system have been broadly categorized into two categories viz. Factory Acceptance Test (FAT) and Site Acceptance Tests (SAT). These tests have been tailored to ensure design, construction and performance requirements of the equipment. This testing manual includes High Voltage Switchboards, Low Voltage Switchboards, Transformer, Diesel Generator Sets, Induction Motors, Cables, Un-interrupted Power Supply (UPS), Ring Main Unit, Light Fittings, MOV Actuators, Isolator Switch and Earthing Systems etc. However in this Paper only highlights the high voltage cables and related test methods - from EPPM.
