Advancements in Electrical Power System Testing

The testing and commissioning of electrical power systems has evolved significantly over the last several decades. Advancements in testing methodology and diagnostic equipment have provided the owners of electrical power infrastructure tremendous amounts of data to determine bench marks and condition so that informed decisions can be made regarding the safety and reliability of electrical power system components. Updates to the NETA testing standards will be highlighted as well as references to other industry standards.

Protective Relays

Protective relays have been around as long as electricity has been around; however, changes in protective relaying occur constantly. Look for articles that deal with major changes in the last decade and new ways to address old problems.

Articles Due: April 15, 2016

Electrical Risk Assessment

The release of NFPA 70E 2015 introduced significant changes to the idea of risk and the requirements for PPE. It specifies that in certain cases during normal operation of electrical equipment, when specific criteria are met, PPE may not be required. This places renewed emphasis on the maintenance activities and records of electrical equipment, the past year of this standard being in effect, as well as in the future.

Informative Annex F contains very detailed information on the Risk Assessment Process. Many in the electrical industry may benefit from a deeper understanding of the Risk Assessment Process especially in cases where risks associated with electrical equipment are only some of the risks they may encounter.

Acceptable articles will cover specifics regarding the electrical risk assessment outlined in Chapter 1 of NFPA 70E for Shock and Arc Flash as well as overall risk assessment strategy for dealing with electrical hazards. This issue will cover the energized work permit as well as decision making processes for implementing energized electrical work permit IAW NFPA 70E-2015 Annex J.

Substation Automation

Substation automation refers the process of controlling electrical power system devices using data from intelligent electronic devices (IED), control and automation capabilities within the substation, and monitoring and control functions from remote users with the ultimate goal of reducing outage frequency and duration. The four major areas consist of data acquisition, processing and supervision, control functionality, and communications.

IEC 61850 was established with goals of defining standardized parameters for substation automation equipment to increase the interoperability of products from multiple vendors.

Articles covering the overall system process or the specific areas identified above would be acceptable especially from the perspective of a design engineer, a field service technician, or a substation owner.

Medium-Voltage Cable Assessment

Presently there are two major classes of testing routines for Medium Voltage Cables. The first is a withstand test which subjects the cable to a test signal from a choice of voltage sources and evaluates the cable specimens ability to withstand the applied voltage. This test is commonly referred to as a Go-No Go test with no data to evaluate other than Pass/Fail.

The second class is a diagnostic test routine. This class of test results in a data point which can be evaluated against accepted performance criteria to determine acceptability, and also can be used with previous and future test results for trend analysis.

Acceptable articles may focus on the value of beginning the trend analysis during the acceptance-testing phase of a project. Often the acceptance testing routine falls in the withstand category, whereas in a service aged application, customers and technicians may demand a more complex diagnostic routine.

The ANSI/NETA ATS-2017 revised edition release will take place just prior to this issue. Any changes affecting the acceptance testing specifications will also be addressed in this issue.

Partial Discharge (PD) Testing

The Partial Discharge Testing Industry seems to have settled on a three-tiered system to describe the levels of test routines offered. Level I, referring to a non-invasive, no outage required, survey of electrical equipment operating at greater than or equal to 2300 Volts, which results in qualitative data: PD possibly exists, or PD is not present. Level II, referring to somewhat invasive test routines where short outages may be required for connections of sensing devices, with data being somewhat more quantitative, with Decibels, Volts, Coulombs being observed and recorded from areas of the system, still energized by normal power supply at nominal system voltage. Level III refers to the most invasive PD testing, where the system is evaluated for partial discharge at voltage level which may exceed nominal system voltage, and may be supplied by test sources not necessarily with the same characteristics as the normal power system.

Acceptable articles may include an analysis of a typical facility and the corresponding results from level I, II or III testing routines, consisting of types and quantities of deficiencies found, as well as the theory of PD detection associated with each level and how they differ.

Articles Due: April 17, 2017

Medium-Voltage Circuit Breakers

Medium Voltage Circuit Breakers vary widely in construction type and operating characteristics. OEM devices can utilize air, oil, vacuum, and SF6 technology for interruption. In addition to original equipment designs, there are many retrofit and retro-fill solutions available to the industry. Air circuit breakers can be replaced with vacuum technology and traditional stored energy mechanisms can be replaced with magnetically held mechanisms to name a few. Diagnostic testing routines can be applied to allow for more predictive maintenance schedules and repairs.

Acceptable articles may focus on the theory of one or more predictive tests available, case studies involving one or more of the testing technologies, or the importance of circuit breaker performance as increasingly understood in arc flash safety.

  • First-Trip Testing
  • Time-Travel Analysis
  • Vacuum Bottle Testing

Articles Due: July 21, 2017

Electrical Safety

NFPA 70E-2018 will be released by the publishing of this issue. Often the NFPA 70E is described as the industry recognized standard. However there is another standard that may be applicable based on the facility being discussed, the National Electrical Safety Code (NESC).

Acceptable articles would include an overview of when to apply each safety standard and any significant differences between the two as it pertains to the daily work of a facility manager, engineer, or test technician. Also, articles covering significant changes to the NFPA 70E from a broad overview perspective, or a focus on a specific change and the possible ramifications to the electrical testing industry would be acceptable.

Spring (February/March) 2018

Articles Due: October 20, 2017

Rotating Machinery

Rotating machinery refers to both motors and generators, AC and DC, with many construction variances designed for specific applications. Rotating machinery is an area of knowledge where a large percentage of NETA techs could benefit from an article in the basics of construction and types of motor commonly found in the industry. Additionally, the 2018 ECS is scheduled to be released in this issue.

Acceptable articles may be a general overview of rotating machinery, specific testing routines applied to rotating machinery, or complex commissioning of rotating machinery including load banking of generator apparatus and complex rotating machinery protection schemes.

NERC Compliance for Transmission, Generation, and Distribution

The purpose of the North American Electric Reliability Corporation (NERC) is to ensure all transmission and generation Protection Systems affecting the reliability of the Bulk Electric System (BES) are maintained and tested. NERC is a not for profit corporation. The Federal Energy Regulatory Commission designated NERC as the ERO on July 20, 2006. Electric reliability organization (ERO) refers to NERC's role as the independent entity that develops and enforces mandatory standards for the Reliable Operation and planning of the Bulk-Power System throughout North America, as called for in the Energy Policy Act of 2005. PRC-new standards should be out around this time.

Acceptable articles would include a summary of changes to the PRC standards, or a spotlight on one or more significant changes and how it will affect the electrical testing industry.
