Shipment of outdoor current transformers 35 kV

22-12-2022

MVT PLUS has supplied complex 35 kV cast resin outdoor current transformers.

The transformers are designed to replace existing oil-insulated ones. The customer provided high requirements for the manufacture of current transformers, namely:

Primary current 150A
Secondary terminal current 5 A
Number of secondary windings 4
Number of windings for measurement, 1 – 0.2S
Safety factor of devices for measuring windings, FS – 20
Load for measurement windings, VA - 20
Number of windings for protection, 3 – 10P
Limit factor for protection windings, ALF – 30
Load for protection windings, VA - 30
Thermal withstand current, Ith/3 sec – 25 kA

Summarizing the characteristics provided by the Customer, the parameters of the current transformers were as follows:

Current transformer SMTSM-3804L
150/5/5/5/5
0,2s/10P/10P/10P
20/30/30/30VA
FS20/ALF30
Ith/3sec 25 kA

The total number of transformers delivered is 3 units.

These transformers will allow the customer to save on maintenance, more accurately measure electricity consumption and transmit a signal to protection terminals, which is especially important for electricity distribution facilities.

MVT PLUS current transformers have all the necessary certificates in accordance with the requirements of the IEC standard and meet high quality standards. The implementation of this project confirms our ability to carry out complex projects and requests from our customers in the supply of informants for the electric power industry.
