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 ...

[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, ...

Which is the best current sensor for your power measuring application? Solid-core current sensing technology provides good performance at low cost. But split-core sensors are making strong progress ...

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 ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...
