Utility power meters often must rely on a current transformer for polyphase applications. Current transformers have drawbacks, however. They are relatively expensive and require additional copper ...

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 ...

[Renaud] built a AC power meter from scratch. While commercial power meters like the Kill A Watt are available [Renaud’s] build gives an interesting insight into the methods used. At the heart of ...

Promising to lower the BOM for polyphase energy meters, the MAXQ3108 and DS8102 chipset replace three high-cost current transformers with three low-cost shunts. The DS8102 integrates two second-order, ...

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 ...

GE Digital Energy announces a new family of ITI Outdoor Medium Voltage (MV) Instrument Transformers that includes voltage and current instrument transformers in the 15kV, 25kV, and 34.5kV class GE ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...

Utility power meters often must rely on a current transformer for polyphase applications. Current transformers have drawbacks: They are relatively expensive, require additional copper wiring, and can ...
