the maximum load

Burden is the maximum load that a voltage transformer or potential transformer can support while operating within its accuracy rating.

For examples, products used by public utilities for determining electricity usage must be 480 volt 3 phase to 240 volt 3 phase transformer since these voltage or potential transformers are used for billing customers. Because they are used mainly in a monitoring capacity, however, voltage or potential transformers generally require greater accuracy. Siemens Transmission Products offers all key elements including power transformers, gas-insulated and / or air-insulated switchgear and components, individually or bundled, with related engineering.

Until now, SF6-free voltage transformers were available for voltages up to 245 kV. Recently, Siemens has succeeded to expand the blue portfolio, which exists of a broad spectrum of CO2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage transformer. Hereby blue products enter the highest available voltage range in Germany of 420 kV. A further step to a sustainable and reliable power transmission. Siemens has been awarded its first order to deliver six newly developed 420 kV blue voltage transformers by a German transmission system operator (TSO).

First SF6-free voltage transformers for 420 kV. A change in the input voltage causes the magnetization current to change and produces a proportional flux change. As the primary voltage increases the secondary voltage continues to increase up to a point of discontinuity, or secondary resonance, where an abrupt increase, about 20 %, in secondary voltage occurs.

There is no method for the regulation of the output against changing input voltages in a conventional transformer. The primary current increases to maintain the original flux level. This transformer is not designed as a self-locking one.

Voltage instrument transformers VTS 12 complied with all the tests according to ČSN EN 60044-2. In cases where the substitution for the older types of transformers (various producers) is required, we supplytransformers VTS 12 with modified basic plates that have identical mounting spacing to spacing of the substituted types. Transformers VTS 12 with fuse are provided with epoxy extender, holder and fuse enclosure of type SIBA (0.3 A or 0.6 A). Extender with fuse can be dismounted.

They are designed for measuring and protection of high voltage distributing equipment for indoor design. They are designed for the use in the high voltage systems. The screws connecting the conductors are only accessible after the current transformer has been short-circuited using the short-circuit slider.

This guarantees the protection of your transformers and measuring devices, and ensures safe, precise work. Oil Impregnation: Heat and vacuum are applied to the fully insulated windings after assembly of the magnetic unit for drying purposes, followed immediately by oil impregnation procedure. Hermetic Seal: Oil volume variations are compensated with stainless steel bellows placed in the head of the Inductive Voltage transformers.

Production:EMEK voltage transformers are manufactured in Ankara Turkey. IME voltage transformers comply with EN / IEC 61869-1, EN / IEC 61869-3 standards and can be divided into: They adapt the values ​​of the primary voltage to the characteristics of the measuring or protection equipment, providing a proportionally lower secondary voltage to the standard 100V values ​​(other values ​​on request).
