sovitusmuunninlaitteet

Sovitusmuunninlaitteet, or voltage transformers, are electrical devices used to step down high voltage levels to lower, more manageable levels for measurement and protection purposes. They are commonly used in power systems to monitor and protect equipment from voltage surges and fluctuations. Voltage transformers are designed to provide accurate and reliable measurements of voltage levels, which are crucial for the safe and efficient operation of electrical systems.

There are two main types of voltage transformers: potential transformers (PTs) and capacitor voltage transformers (CVTs). Potential transformers are used in low-voltage applications and are typically rated at 110V or less. They consist of a primary winding connected to the high-voltage side of the power system and a secondary winding connected to the low-voltage side. The secondary winding is usually rated at 120V or less, depending on the specific application.

Capacitor voltage transformers, on the other hand, are used in high-voltage applications and are typically rated at 115kV or higher. They consist of a primary winding connected to the high-voltage side of the power system and a secondary winding connected to the low-voltage side. The secondary winding is usually rated at 120V or less, depending on the specific application. CVTs use a capacitor to provide a high impedance path for the primary winding, which helps to reduce the size and cost of the transformer.

Voltage transformers are essential components in power systems, as they provide accurate and reliable measurements of voltage levels, which are crucial for the safe and efficient operation of electrical systems. They are used in a wide range of applications, including power generation, transmission, and distribution, as well as in industrial and commercial settings.
