Welcome to the Homepage of the THETA Ingenieurbüro GmbH in Dresden.

We are deal­ing with the diag­no­sis, assess­ment and devel­op­ment of elec­tri­cal switchgears and devices. We can offer you a wide range of ser­vices due to our long-last­ing expe­ri­ence and our well trained employees.

Have a look around the fol­low­ing pages and get famil­iar with us and our range of services. 
 
Diagnosis

We sup­port you in search­ing for and find­ing pos­si­ble caus­es of errors, whether through mea­sure­ments or calculations.

 
Assessment

The assess­ment is car­ried out in accor­dance with the applic­a­ble stan­dards and reg­u­la­tions. If desired, sug­ges­tions for opti­mi­sa­tion can be provided.

 
Enhancement

Cal­cu­la­tions and mea­sure­ments are used to opti­mise your devices and iden­ti­fy poten­tial savings.

Software pressure calculatio

The soft­ware is a Win­dows-based pro­gramme for cal­cu­lat­ing the over­pres­sure in elec­tri­cal instal­la­tions and instal­la­tion rooms in the event of a fault arc. The pres­sure cal­cu­la­tion is based on the assump­tion that the pres­sure spreads simul­ta­ne­ous­ly and even­ly through­out the entire vol­ume. The pro­gramme can be used to take into account the pres­sure relief of the fault space into up to three con­sec­u­tive relief spaces and into the sur­round­ing area.

Micro-ohmmeter LoRe

The LoRe micro-ohm­me­ter is the pre­cise solu­tion for deter­min­ing the small­est resis­tances in the range from 10 nΩ to mΩ. With a res­o­lu­tion of 1 nΩ and a mea­sur­ing cur­rent of up to 90 A, it deliv­ers reli­able mea­sure­ment results for eval­u­at­ing the qual­i­ty fac­tor of elec­tri­cal connections.

Internal Arc Fault

We have more than 20 years of the­o­ret­i­cal and prac­ti­cal expe­ri­ence in assess­ing the effects of arc­ing faults and cal­cu­lat­ing the pres­sure gen­er­at­ed by arc­ing faults.

If you need assis­tance in devel­op­ing a new switchgear or sta­tion, no prob­lem. Just get in touch with us. Learn more

Infrared diagnosis

Con­nec­tions age due to chem­i­cal reac­tions at the micro­con­tact points or actu­al con­tact points dur­ing their oper­at­ing life, and their con­nec­tion resis­tance and thus the result­ing tem­per­a­ture increases.

Measurement

We take into account the envi­ron­ment of the con­nec­tion and its influences.

Evaluation

This makes it pos­si­ble to make a clear state­ment about the con­di­tion of the connection.
