Communications Security for Field Testing Organizations
Cybersecurity is one of the greatest challenges to grid reliability. As more facilities and devices become IP-routable communications-enabled, the threats multiply along with the incredible productivity gains. This additional complexity impacts the work of field testing organizations in the form of a bewildering milieu of new technologies, processes, and regulations. Without awareness of the threats and security best practices, it …
A Brief Summary: IEEE Guide for Dielectric Frequency Response Test
The Institute of Electrical and Electronic Engineers (IEEE) Standards Association recently approved the publication of IEEE Std. C57.161–2018, Guide for Dielectric Frequency Response Test. The work was developed within the IEEE Transformers Committee and the Dielectrics Subcommittee. The industry needed a document to better understand the field application of a non-intrusive and non-destructive method to assess the condition of oil-paper …

Obstacles to Measuring Power Transformer Winding Resistance
DC winding resistance is a simple concept that relies on the fundamental application of Ohm’s Law. It is a powerful tool to determine continuity in power transformer winding circuits, specifically connections and tap changer contacts. However, performing a dc winding resistance test presents several technical difficulties that must be overcome: The power transformer’s magnetizing inductance must be removed through saturation …

Practice Theory: High-Voltage Laboratory Testing of New Electrical Products
High voltage is defined by the National Electrical Code (NEC) as any voltage over 600V and by the International Electrotechnical Commission (IEC) as any voltage greater than or equal to 1,000V. NETA uses the IEEE definition: any voltage greater than or equal to 100kV and less than or equal to 230kV. Other standards and industries define high voltage at different …
