Dissolved gas analysis (DGA) in transformers is a very successful periodic screening method to identify transformers that may be having problems. It is a symptom-based assessment of health, rather than a condition-based assessment. That is because the gases themselves do not cause failure, but are just by-products of deteriorating insulation caused by abnormalities such as
hot spots or electrical discharges. The abnormalities are what might fail the transformer. If the transformer loses fault gases, the...
By R.W. Hurst, Editor A distribution transformer is a critical component of the electrical power system, used to reduce the voltage of electrical energy for electric power distribution to end-users. It plays a vital role in voltage regulation and load management, ensuring the efficient and reliable...
A transformer relies on electromagnetic induction through coils to transfer electric energy between two or more circuits. Varying current in the transformer’s primary winding creates varying magnetic flux in the core, which produces varying electromotive force (EMF) or voltage in the...
Electrically conductive pastes in high-voltage transformers BY LISA RINALDO, Prohm-tect As with other components of North American infrastructure such as wastewater and stormwater systems, much of the continent’s electrical grid faces long-term problems. Aging facilities, rising energy...
The evolving demands of modern power grids necessitate the adoption of advanced technologies that can provide enhanced efficiency, reliability, and flexibility. Smart transformers are at the forefront of this technological revolution, offering a range of capabilities that significantly improve the...
The Growing Need for Safer and Greener Transformer Oils Transformer oil plays a vital role in the operation and longevity of power transformers, providing insulation, cooling, and arc suppression. Traditionally, mineral oil has been the industry standard due to its effective dielectric properties...
The Growing Concern of Transformer Fire Risks An Electrical Substation Transformer is a critical component of modern substations, playing a vital role in the transmission and distribution of electricity. However, due to the high-voltage operations, flammable insulation materials, and exposure...
The Growing Transformer Supply Crisis The global transformer supply chain is facing unprecedented challenges, with utilities worldwide struggling to procure essential equipment due to material shortages, manufacturing delays, and logistical constraints. Transformers are the backbone of electrical...
Power transformers are critical assets in electrical transmission and distribution networks. Their failure can lead to widespread outages, costly downtime, and potential safety hazards. As transformers age and operate under varying electrical and environmental stresses, degradation becomes...
