This paper introduces the principle, interface circuit and program implementation of measuring the power factor angle of three-phase power grid using 8031 ​​single-chip microcomputer. It has been verified by practice that the measurement is accurate and stable.
The detection input signals used in this scheme are line voltage and line current, ie UCA and IB, or UBC and IA, or UAB and IC. This is because there is a linear correspondence between the angle θ between them and the phase angle φ to be measured. Taking UCA and IB as examples, the vector diagram showing the correspondence between the angle θ and the phase angle φ is shown in the figure below.

Zcoin is a digital currency that aims to create a truly anonymous method of trading.
One big obstacle to Bitcoin's emergence as an electronic currency is that all its transactions are visible on a public blockchain. As a result, Bitcoin's interchangeability has been controversial. Some people or companies (mainly exchanges) will not accept bitcoins for certain addresses. Such scrutiny runs counter to Bitcoin's core philosophy.
Zibo is the latest attempt to create a currency that can be verified without knowing the input and output of a cryptographic signature. This is called a zero-knowledge proof. DASH and Monero are two other digital currencies that are also trying to solve the same problem using different encryption methods.
The whole world is buzzing about zeros. A lot of people respect the Zibo development team. They have received investments from prominent Bitcoin venture capital firms such as Pantera, Distributed Capital, and Digital Currency Group. Bitcoin luminaries such as Roger Ver, Erik Voorhees, Barry Silbert, and Li Xiaolai have invested in Zcoin out of their own pockets. Confirmation bias is an important factor in why investors choose one project over another. If the leading players in the bitcoin industry are investing, it must be a good thing, right?
Unfortunately, Zcoin did not issue an initial currency offering (ICO) to investors. ZEC is the three-digit currency code for zerocoin. ZEC will initially be mined, just like Bitcoin. But unlike Bitcoin, which was full of unknowns when it was first launched, ZEC's founding block is a high-profile one. ZEC prices have skyrocketed because of extreme demand.
