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 ...

The same TTR test circuitry that is in the existing TTR300, TTR310 and TTR330 can be found in the latest model. June 15, 2009 The same TTR test circuitry from Megger that is in the existing TTR300, ...

The latest version of RelaySimTest (V3.20) enables users to extend the benefits of system-based testing to transformer protection 1. Instead of adopting the usual approach of simply testing the ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

So there I was with this mystery transformer on which someone put a label showing three different speaker load impedance, but with no indication of what the intended primary winding impedance happens ...

Effective transformer maintenance depends on dissolved gas analysis. Effective maintenance of liquid-filled transformers begins with prevention of failure by testing transformer oil for unusual ...
