Electrolaboratory TM-Electro will quickly and efficiently carry out electrical measurements

We will promptly answer all your questions, calculate the cost estimate. If you are planning an inspection, issued an order, the term of the Technical Report has expired. We will carry out acceptance, operational or preventive tests.

Electrical measurements are carried out by qualified personnel using modern electronic equipment passed annual verification.

Loop phase zero. From these protocols of the Technical Report, it is possible to determine Current state electrical installations. All measuring work is performed by the TM-Electro electrical laboratory only with a visit to the facility. If a shutdown is required, the shutdown schedule is agreed with the Customer.

TM-Electro does not issue a Technical Report without a visit... For more than 13 years of work, a huge practical experience has been accumulated in electrical measuring work (measurement of insulation resistance, measurement of a zero phase loop). Resistance measurement is one of the most requested protocols in the Technical Report.

With the help of digital devices, the integrity of the insulation of cable lines is checked. The readings of the devices are compared with the reference ones and are recorded in the report, in the form of a table. The table also indicates the marking of the cable lines and the cross-section. In the last column it is written - whether the insulation meets the standard or not.

In case of non-compliance, the remark is entered into the List of Defects and must be eliminated. Measuring the insulation resistance allows you to identify the problem before an emergency occurs.

Poor insulation is a leading cause of short circuits, fires and electric shock.

The photo below shows examples of dangerous situations with an electrician, from the practice of our ETL. Complete burnout of the insulation of the electric wire and the case of the circuit breaker (in a wooden house!).

Attention! Often, dangerous electrical faults cannot be identified by visual inspection.

Measurements are carried out in accordance with the test frequency table or at the request of the person responsible for the electrical equipment (after all, he is responsible for the safety of the facility). To measure resistance, the time-tested Sonel MIC 250 device is usually used. We will promptly answer all your questions and calculate the cost estimate.
