So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

Transformer Test Equipment consists of specialized test modules or systems used to test and/or monitor electrical and mechanical parameters of transformers and other related devices. Transformers can ...

The purpose of electrical signature analysis (ESA) is to use the magnetic field in the air gap of an electrical machine to evaluate power quality — the condition of the electrical and mechanical ...

Single-phase transformers accept single-phase AC power and output single-phase AC power, typically at a higher or lower voltage level. Energy is transferred from one circuit to one or more circuits ...

Current transformers or CTs are indispensable anywhere high currents are measured and processed. These instrument transformers effectively diminish high-voltage current flows for a convenient way to ...

In high-voltage power transmission systems, transformer valves perform critical fluid containment and isolation functions. Operating within the oil circuits of oil-immersed power transformers, these ...

Data centers have become the largest driver of a surging electricity demand that is straining US power grids. But the AI data center boom has also accelerated investment in a technology that could ...

The first case study is about an on-site measurement on a 66kV to 132kV reference VT. The secondary winding has two taps for adapting the voltage ratio between 132kV/√3:110V/√3 and 66kV/√3:110V/√3.
