Today’s boats and motors most often use color-coded blade fuses instead of the traditional glass tube style. Troubleshooting electrical circuits equipped with this new type of fuse is awkward as the ...

There’s a problem with fuses. On the face of it, testing would seem to be a one-shot deal — exceed the rated current and see if it blows. But once you know the answer, the device is useless. If only ...

This new three -phase test instrument addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial ...

Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

Smaller, lighter and with a higher output power than other three-phase instruments, Megger’s SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

I recently acquired a Noritake Itron graphical VFD, 'as is'. The model number is GU126x64F-K612A4-01. The problem is, it doesn't seem to work at all. I tracked down a nice discussion threadover at bit ...
