Welcome to TeCo Lanz

I provide technical consulting primarily in the field of high voltage machines, some examples of possible scopes are provided below.
Machine types where I do have significant know how and experience are:
Traction motors
Hydro generators
Turbo generators, steam and gas turbine driven

As per my technical background, I focus on stator windings in most cases. However, I do have some in-depth knowledge experience on "neighboring" topics, as e.g. High voltage bushings, insulated bus bars and similar.
Primarily, following gene

If your request is not matching any of the examples provided below: Just get in contact with me…

Design support

Stacks Image 177
You need design support for stator windings as geometrical calculations of involutes, dimensioning of gradings, design for manufacture? We do have the knowledge and tools required.

Manufacturing support

Stacks Image 185
Setting up a new production facility or new production equipment? I may help in defining tools and setting parameters to achieve reliable windings.

Support in diagnostic testing

Stacks Image 191
Not sure what tests to perform to assess fitness of stator winding for purpose? Or having uncertainties what test to perform and how? I am here to assist you.

Partial discharge testing

Assessing phase resolved partial discharge pattern reuires experience and design knowledge of specific winding. I do have significant experience and can support you, so that the PD patterns acquired become a useful tool to assess the state of the winding.
We have experience with PD equipments of major brands.

Visual Inspections

Visual inspections may provide a lot of information, provided the inspection is performed by experienced engineers. Design knowledge is a key.
I am offering visual inspections, including endoscopy.

Repair advice

How to address a damage found during inspections?
I can support you in that respect.
In case winding work is required, I established relations with companies which may provide a good winder to perform the work required.

Machine assessment

Stacks Image 207
You own a vintage machine, and are interested in when a full replacement or a rewind only is to be considered? Or a damage occurred and questions arise what repairs are required? I can support you in such cases.

Quality assessments

Stacks Image 225
You search a competent inspector, taking care of the manufacturing of your winding?
I provide witnessing of factory tests. Typical scopes include dimensional checks, dielectrical testing and asessment and visual inspections.

Failure analysis, RCA

Stacks Image 256

A failure may have significant impact. It is thus important, to assess the rooot cause of the failure to prevent subsequent failures driven by same flaw.
I do perform RCA's, involving further resources of my network as a specialized lab, specialist in mechanical calculations or any specialist required.

Site supervision

Site supervision during diagnostic testing, repair activities or scheduled outages are a common scope.
