ABB said it has successfully developed and tested an 1100 kV "ultrahigh-voltage" direct current converter transformer, breaking the record for the highest DC voltage levels ever, and facilitating more ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

Solar panels have become a key part of the transition to cleaner energy. Homeowners and businesses are investing in solar systems to reduce reliance on fossil fuels and lower ...

In high voltage applications involving tens of thousands of volts, too often people think about the high voltage needed but don’t consider the current. This is especially so when part of the circuit ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system, particularly sags that trip loads.

We’ve seen a fair amount of Tesla coil builds, but ones using vacuum tubes are few and far between. Maybe it’s the lack of availability of high power tubes, or a lack of experience working with them ...
