Approaching our 35th year in 2022, Tortech remains as busy as ever! 2021 has proved to be a productive and yet complex year navigating the challenges that faced our state. Tortech remained opened and operating producing Medical isolation transformers for our hospitals and ICU’s and large 3 phase isolation transports for rail and critical infrustructure projects nationwide.
Many customers come to Tortech after buying sub standard transformers that do not operate well or a poorly made. No only does this pose risk to your device but to the safety of your home. There is a huge variance in how voltage converter transformers, particularly step down transformers on the market are made.
The general isolation transformer has a input and output winding isolated from each other. It incorporates a screen but not a full FARADY screen
This is one convenient type of discharge reference source for Partial Discharge applications. It can be used to cross check electrical calibrators for partial discharge.
The picture below is a 3-phase 25kVA -415/415V, with taps on the output winding. This 3 phase transformer is built using 3 single phase toroid transformers. A 3 phase transformer…
Assembled and tested on load here at Tortech our single to three phase converters are an ideal cost effective solution to provide 3 phase power from single phase power. Single…
An alternative to the Rotary phase converter is a Variable frequency converter. A VFD is used for low power applications (only anything below 4KW) . A cost alternative to Single to…
