Loop phase zero. From these Technical Report protocols, the current state of the electrical installation can be determined. The TM-Electro electrical laboratory performs all measuring work only on site. If a shutdown is necessary, the shutdown schedule is agreed upon with the Customer.

TM-Electro does not issue a Technical Report without an on-site visit. Over more than 13 years of work, we have accumulated vast practical experience in carrying out electrical measuring work (measuring insulation resistance, measuring phase zero loops). Resistance measurement is one of the most popular Technical Report protocols.

Using digital instruments, the integrity of the insulation of cable lines is checked. Instrument readings are compared with reference standards and recorded in a report in the form of a table. The table also indicates the marking of cable lines and cross-section. In the last column it is written whether the insulation complies or does not comply with the standard.

In case of non-compliance, the remark is included in the List of Defects and is subject to elimination. Measuring insulation resistance allows you to identify a problem before an emergency occurs.

Poor insulation is the main cause of short circuits, fires and electric shocks..

The photo below shows examples of dangerous situations with electrical equipment from the practice of our ETL. Complete burning of the insulation of the electrical wire and the body of the circuit breaker (in a wooden house!).

Attention! Often, dangerous electrical installation 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 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.
