NТАМI

Anti-resonant voltage transformers of the NTAMI-6 U3 and NTAMI-10 U3 series are high-precision devices designed for large-scale conversion of alternating current electrical voltage with a frequency of 50 Hz. They provide the supply of measuring information signals to electrical measuring instruments, as well as to protection and signaling devices in networks with an isolated neutral. These transformers are designed to operate in electrical networks with a nominal voltage of 6 or 10 kV.

Design features

The NTAMI transformer consists of an active part located in a tank filled with transformer oil and a cover. The active part consists of armored magnetic cores and windings wound on a cylinder made of electrical cardboard. For connection to the electrical installation, the transformer is equipped with porcelain high and low voltage inputs; the inputs are located on the transformer cover. The transformer cover has a plug for taking a sample and filling oil. There are four holes in the bottom of the tank for fastening the transformer at the installation site. The transformer is equipped with a special boss for connection to the grounding circuit. The design provides reliable insulation and protection from external influences, which guarantees durability and safe operation.

Advantages of NTAMI transformers

1. Anti-resonance properties: The special design of transformers provides resistance to ferroresonance phenomena, which increases the reliability of operation in networks with an isolated neutral.
2. High measurement accuracy: Reliability of transmitted signals to measuring instruments and protection systems.
3. Reliability and durability: The use of high-quality materials and modern production technologies ensures a long service life of transformers even under conditions of intensive operation.
4. Multifunctionality: NTAMI transformers are suitable for use in various industries, energy and infrastructure facilities, where precise control of electrical network parameters is required.
