3-phase compensating choke INK 1.5-400V INK 3-1,5-400

Capacitor banks – network optimization and cost reduction

INK capacitor banks are elements used to correct the power factor (cos φ) in electrical installations. By compensating for capacitive reactive power, they contribute to improved energy efficiency, reduced network losses, and lower electricity costs. The INK 3-1.5-400 model, with a power of 1.5 kVar and a voltage of 400V, is designed for use in three-phase systems.

Application and benefits:

• Compensation of capacitive reactive power: The capacitor effectively eliminates the negative effects of excessive reactive power, especially in installations with capacitive loads, such as modern LED lighting or switch-mode power supplies.
• Improved energy efficiency: Reducing reactive power means less energy loss in wires and devices, which translates to lower electricity bills.
• Increased network capacity: Reactive power compensation releases power reserves in the network, allowing the connection of additional loads without the need to expand infrastructure.
• Device protection: Voltage stabilization and reduced network load affect the longer lifespan of electrical devices.
• Compliance with standards: Maintaining the power factor at an appropriate level is often required by energy suppliers and allows avoiding financial penalties.

Construction and parameters:

The INK 3-1.5-400 capacitor is characterized by a solid construction based on a core made of high-quality transformer sheet steel and a copper winding (standard). Vacuum impregnation in class H varnish ensures high resistance to environmental conditions and long-term reliability. The device has protection in the form of a thermal overload protection and a protection degree of IP00, which means there is no protection against access to live parts. The capacitor is designed for continuous operation in an ambient temperature of up to 40°C. Compliance with PN-EN 60076-6 guarantees product safety and quality.

This capacitor has a power of 1.5 kVar and is adapted to operate at a rated voltage of 400V and a frequency of 50Hz. The insulation class is F (155°C), and the degree of protection is IP00. Protection is provided by a thermal overload protection, and the inductance of the capacitor is approximately 340 mH.
