Sandvik CoromantWed, 10 Sep 2014

In the third instalment of its ‘Looking Ahead’ series about future manufacturing challenges driven by technological, demographic and environmental changes, toolmaker Sandvik Coromant explores the ramifications that keeping pace with — or falling behind — the coming technology shifts will have on the success of businesses. According to Sandvik Coromant’s white paper ‘Manufacturing Intelligence’ and its video ‘Looking Ahead’, we are now on the verge of the fourth industrial revolution, ...

Application note: two-wire virtual remote sensing for voltage regulators downloadweblink

Linear TechnologyWed, 10 Sep 2014

Wires and connectors have resistance. This simple, unavoidable truth dictates that a power source’s remote load voltage will be less than the source’s output voltage. In this application note from Linear Technology, figure one shows this and implies that intended load voltage can be maintained by raising regulator output. Unfortunately, line resistance and load variations introduce uncertainties, limiting achievable performance. Figure two illustrates one compensatory approach. Locally ...

Omicron's CPC 100 testing solution with the CP SB1 switchbox

White paper: reliable demagnetisation of transformer cores download

OMICRON electronicsFri, 5 Sep 2014

Whenever a power or distribution transformer is isolated from the power system, it is likely that residual magnetism remains in the core due to the phase shift. However, residual magnetism also occurs when performing winding resistance tests. As manufacturers use these measurements in their routine testing, transformers can be regularly influenced by the effect of residual magnetism.

Application note: diode turn-on time induced failures in switching regulators download

Linear TechnologyThu, 4 Sep 2014

Most circuit designers are familiar with diode dynamic characteristics such as charge storage, voltage-dependent capacitance and reverse recovery time. Less commonly acknowledged and manufacturer specified is diode forward turn-on time. This parameter describes the time required for a diode to turn on and clamp at its forward voltage drop. Historically, this extremely short time, units of nanoseconds, has been so small that user and vendor alike have essentially ignored it. It is rarely ...

White paper: testing CT in delta winding download

OMICRON electronicsThu, 4 Sep 2014

Measuring the ratio of a current transformer (CT) mounted in a transformer delta winding can often be confusing if the electrical principals are not understood. This can be the case especially if there is wiring error leading to incorrect identification of the CT being tested. This paper from Omicron discusses the principles around performing a ratio measurement of CT’s mounted in delta winding. A case study is also presented to explain the test results due to incorrect CT wiring.
