The International Electrotechnical Commission (IEC) and IEEE on Sept. 19 released a joint publication of new international guidelines for condition monitoring of electrical equipment installed in nuclear power plants.
The series of international standards and guidelines, IEC/IEEE 62582, "Nuclear power plants -Instrumentation and control important to safety—Electrical equipment condition monitoring methods," is intended for use by nuclear power plant operators, system evaluators, test laboratories, and licensees of nuclear power plants. The two organizations said the standards are particularly important because they focus on condition monitoring of electrical equipment that performs vital nuclear power plant safety functions.
“While many countries and individual power utilities are pursuing smart grid strategies that integrate renewable energy supplies, nuclear plants will continue to provide an important source of power for society for many more years and the industry needs to continue to focus on the safety of these plants,” said Gary Johnson, chairman of IEC SC45A and senior safety officer at the International Atomic Energy Agency (IAEA).
The IEC and the IEEE Standards Association (IEEE-SA) developed the standards to promote international uniformity in the practice of electrical equipment condition monitoring. The new series of international standards includes the following:
- IEC/IEEE 62582-1, Part 1: General
Establishes the need for condition monitoring and summarizes the various techniques plant operators can use as applicable and appropriate to their plants.
- IEC/IEEE 62582-2, Part 2: Indenter modulus
Contains detailed descriptions of condition monitoring based on indenter modulus measurement techniques, which are primarily used to test cable jackets, insulation and o-rings that are installed in low-voltage environments.
- IEC/IEEE 62582-4, Part 4: Oxidation induction techniques
Specifies methods for using oxidation induction techniques to take samples from organic and polymeric materials in electrical equipment, e.g. cable jackets or insulation.
