The PCUS is the most popular universal and reliable solution for 10 kV switchgear assemblies, transformer substations, and electrical installations in industrial facilities and residential buildings.

Features

Main Functions of the PCUS

• Receiving and distributing three-phase AC electrical power at 50 Hz and 6 (10) kV in isolated-neutral networks.
• Switching of various power circuits.
• Protection against short circuits, overloads, unacceptable voltage deviations, and other fault conditions.
• Metering of consumed electrical energy.
• Measurement of key electrical network parameters, including current, voltage, power, power factor, and more.

The PCUS is a key component of electrical distribution systems, ensuring a reliable and uninterrupted power supply for consumers.

Chamber Construction

The PCUS (Prefabricated chamber of unilateral service) is a metal-enclosed cubicle housing 6 (10) kV electrical power reception and distribution equipment, including:

• Switching devices – circuit breakers, disconnectors, fuses, and related equipment.
• Protection devices – protective relays, automatic circuit breakers, and related equipment.
• Measuring devices – current and voltage transformers, electricity meters, and related equipment.
• Metering instruments – ammeters, voltmeters, wattmeters, and other electrical measuring instruments.

Design Features:

• Single-sided access – all components are accessible from one side, ensuring safe and convenient operation.
• Modular design – the cubicle is built from standardized modules, allowing easy configuration and system expansion.
• Reliable protection – the enclosure is designed to protect personnel from electric shock during operation.

High voltage prefabricated chambers of unilateral service are supplied fully factory-assembled and ready for installation, significantly reducing installation time and simplifying commissioning.

High-Voltage Capacitor Banks

High-voltage capacitor banks (HVCBs) are integrated electrical systems designed for reactive power compensation in power distribution networks. Their primary purpose is to improve the efficiency of power transmission and minimize energy losses throughout the system.

HVCBs are engineered with high-performance technical specifications, including capacitance, rated current, nominal voltage, and operating temperature range. These parameters are selected individually to meet the requirements of each specific electrical system.

There are two main types:

• Automatic capacitor banks – equipped with an automatic control system that dynamically adjusts to changing load conditions, maintaining a stable power factor.
• Fixed capacitor banks – used in applications with predictable, constant loads where continuous reactive power regulation is not required.

Functions

High-voltage capacitor banks perform the following functions:

• Improving system efficiency by reducing electricity losses; this is important for optimizing system performance and reducing operating costs;
• Compensating for reactive power, which improves power transmission and reduces energy losses; this is particularly important on long transmission lines;
• Stabilizing voltage in the power system by compensating for voltage fluctuations, which ensures more stable operating conditions for electrical equipment;
• Improving the quality of electricity by reducing voltage and current distortion in the system, which is particularly important for preventing damage to electrical equipment and ensuring reliable system operation;
• Reducing the load on transformers, cables, and other electrical equipment, which extends the service life of the equipment and reduces the need for maintenance;
• Energy savings by reducing power losses in the system, which leads to lower energy costs and improved energy efficiency of the power system as a whole;
• They are typically used in situations where the static load is predictable and does not require constant regulation of reactive power.

A key feature of high-voltage capacitor banks (HVCBs) is the use of high-quality dielectric materials and reliable capacitors. Their design is optimized to minimize energy losses while ensuring maximum durability and long-term performance.

If you are looking to purchase a capacitor bank, it is best to order it directly from the manufacturer. Nika Energy is a trusted Ukrainian manufacturer of power distribution systems, offering both ready-made solutions and custom-engineered projects at competitive prices.
