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 ...
Most residences and commercial buildings in the United States currently use an old-style electromechanical utility power meter to track electricity use. The meters are reliable and cheap but ...
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, ...
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 ...
[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 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 ...
