Power Quality

Elgin Power Solutions’ Medium Voltage Capacitors deliver reliable power factor correction, voltage regulation, harmonic filtering, and surge protection, optimizing performance for industries like manufacturing, renewable energy, mining, data centers, and more. Designed for large inductive equipment such as motors and VFDs, our capacitors enhance system efficiency while reducing transformer load. Whether in open substations, mobile units, or pole-mounted configurations, Elgin’s capacitors provide versatile, high-performance solutions tailored to meet your specific power needs.

Elgin medium-voltage power capacitors are known for their high reliability and ease of handling. They are recommended for installation in capacitor banks or harmonic filters to address various electrical system needs, including:

-Power factor correction to avoid penalties
-Series or shunt reactive power compensation to enhance voltage profiles in electrical circuits
-Mitigation of harmonic voltage and current distortions using passive harmonic filters
-Reduction of technical losses in systems

Elgin’s medium-voltage power capacitors are used across a wide range of industries, including manufacturing, utilities, renewable energy, data centers, mining, and more. Each design can be customized to meet diverse application requirements, considering overall power system parameters.

Elgin’s three-phase medium-voltage capacitors leverage advanced technology to effectively support various electrical system applications, including:
-Power factor correction for industrial motors and busbars
-Shunt compensation of reactive power
-Passive harmonic filtration

Internally fused power capacitors are ideal for various electrical system applications, including:
-Static VAR compensators
-Power factor correction to avoid penalties
-Series and parallel reactive power compensation
-Reducing harmonic voltage and current distortions with passive harmonic filters
The fuses address any faulty internal components until the imbalance protection deactivates the capacitor bank. A key benefit of this technology is the increased reactive power within a single capacitor housing, enabling the installation of capacitor banks in smaller spaces where physical space is limited.

Elgin capacitors offer robust protection against voltage surges for medium-voltage motors and generators. Due to their design, medium-voltage rotating machines have less insulation, making them more susceptible to surge and voltage-related failures compared to other equipment in the same facility.

Analysis of such events reveals that the surge wave initially creates a significant potential difference in the machine coil windings, known as a “peak.” This peak places substantial stress on the dielectric insulation of the machines. By incorporating a capacitor with a specific capacitance value into the circuit, the peak is delayed, thereby reducing the potential difference in the windings. Adding a lightning arrester in parallel with the capacitor further enhances the surge protection.

Attention: The capacitor must be installed in a phase-to-ground connection, on the terminal posts of the machine to be protected, and in parallel with the selected lightning arrester.
