Test on amperometric and voltmetric power transformers
Amperometric and voltmetric power transformers -Check
A power or measuring transformer may be damaged during transport, due to micro vibrations. Before commissioning, it is necessary to check that its electrical, insulation and transformation ratio characteristics are correct, with reference to the construction data. Measuring transformers need proper verification and typification for the correct visualization of the measured electrical values. Lictronic has invested in instrumentation and training of its staff, with the creation of a specific division able to certify the measures carried out.
Applications

Types of service
On-site and laboratory verification
Our equipments are portable or fixed and, depending on the activity required, we can provide on-site verification. At our laboratories a conditioned and stabilized room has been set up, where the verifications of the measurement transformers are carried out. The on-site intervention is decisive for the acceptance of the certifying body at the commissioning, or at the restart after a prolonged inactivity.
Measuring transformers
Lictronic has specific equipment to verify the transformation ratio with primary and secondary injection, and polarity detection for measurement transformers. These verifications are necessary before starting up a plant where current and voltmeter transformers are used for the electrical protections.
Power transformers
Insulation and dielectric strength checks are critical prior to start-up. Detection of transformation ratio and polarity are important data in certification sequences. Lictronic has equipment that can verify strength up to 85 kV and insulation up to 5 kV.

Customers' FAQ
After a prolonged stop it is necessary to proceed to the refined cleaning of the MT cells, of the power transformers and related connection conductors, after which it will be indispensable to verify the insulation of the various components and to arrange the strength test, in order to stress potential damages caused by rodents or mechanic ones. We suggest you to provide for the ventilation and drying of the premises before our intervention, to avoid false measurements.
Yes, we can, as we have transportable instrumentation useful for the required verification; you will need on-site support to perform the move, disassembly and reassembly of the various systems. In the preliminary phase we will send you a form to be completed with the data of the devices to be checked.
