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 ...

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, ...

[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 ...

Omicron's CT Analyzer provides fast and cost-effective testing and verification of current transformers for protection and metering applications. It automatically determines all relevant current ...

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 ...

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 ...

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 ...
