As more and more electronics manufacturers started taking advantage of fast-growing high-frequency technologies, product and test engineers have more and more depended on highly linear and robust broadband test equipment to meet their ever-increasing t
A valuable tool for transformer diagnostics is sweep frequency response analysis (SFRA), which consists of measuring the impedance of transformer windings over a wide range of frequencies. Faults, which change either the wind
We’re all well accustomed to the fact that electrical signals travel through wires and PCB traces, so it should come as no surprise that there is also such a thing as “Conducted EMI” - a Electromagnetic Interference (EMI) that travels through a conduct
With the increasing emergence of renewable energy, cable links are becoming longer and longer up to several hundred miles, such as from offshore wind developments or underground land transmission lines for the clean energy po
Winding resistance measurements taken on transformers are essential for type, routine, and field testing. The measurements provide information of conductor losses, winding temperature at the end of a temperature test cycle, a
Partial discharges (PD) are evidence of a degrading insulation system, and if left undetected, may eventually lead to very costly repairs or damaging and dangerous in-service failures.
Increasing Efficiency Regulations of Distribution Transformers Requires the Use of Highly Accurate Transformer Loss Measurement Systems
Throughout the world regulatory bodies are focusing more and more on promoting energy efficient distribution transformers that are to be used in the energy transmission and distribution network.
Typically, there are many industry and product specific electromagnetic compatibility (EMC) standards to comply with when products are sold globally.
