Eaton’s Cutler-Hammer  metal-enclosed medium voltage capacitors, systems and harmonic filters are designed for indoor or outdoor commercial, industrial and utility power systems requiring motor start support, power factor correction, harmonic filtering, IEEE 519 compliance, and increased system capacity. Fixed motor start capacitors are available to assist in motor starting applications. Engineered designs are available with a host of options and accessories to fit the requirements and desired configurations of virtually any installation. Singlestage and multi-stage, tuned or de-tuned filter banks can be supplied. Metal-enclosed medium voltage capacitor banks are designed for industrial, commercial and utility power systems involving motors, feeder circuits, and transmission and distribution lines where power factor improvement is required.

Advantages Eaton’s purchase of the Commonwealth Sprague capacitor systems Eaton’s business, with its over 70 years of market experience, provides a combination that allows the end user to obtain a world-class solution to fill their power factor needs. Quality and reliability are of paramount importance to not only the Eaton engineering team, but are also the backbone of all Eaton products and services. This commitment to quality means the customer can have a great deal of confidence with the medium voltage capacitor or harmonic filter solution from Eaton’ Eaton’s s electrical business.

Benefits Ease of Installation

Safety and Aesthetics are Just Two Compelling Reasons to Utilize Metal- Enclosed PFC Systems

Application Description

Eaton makes installation easy. All systems are completely assembled in the factory, with all equipment pre-wired and pre-tested for easy on-site installation. Only shipping splits must be connected in the field. Splice kits connect bus systems, and control wiring is easily connected at each enclosure. Current limiting fuses, contactor assemblies, and the incoming switch assembly can be removed from the enclosure if needed. Line terminals are completely accessible from the front of the system.

Utility Customers

Personnel Safety

Metal-enclosed power factor correction systems are fully assembled, tested and ready for installation. Very little field assembly is required. Installation and maintenance costs for metal-enclosed systems are low compared to pole and rack mounted capacitor banks. Metalenclosed systems and harmonic filters are less vulnerable to wildlife and airborne contaminants that can cause tracking and faults. In addition, metal-enclosed systems significantly reduce the risks and the associated liability involving untrained personnel. All live parts are contained in a grounded, key interlocked enclosure and no internal hardware is accessible. Metal-enclosed systems are aesthetically pleasing due to their low profile, and can be painted to match the surrounding architecture. These are just some of the reasons more and more utilities are utilizing metal-enclosed capacitor and harmonic filter systems.

Positive mechanical isolating switch with visible disconnect completely grounds and isolates the unit from the line connectors. A screened barrier protects personnel from live parts. All medium voltage doors are mechanically interlocked with the disconnect switch. Key interlocks are provided standard on all enclosure doors, and can be coordinated with upstream disconnect devices. The low voltage control section has a separate door-in-door design, and is segregated from the medium voltage sections so that an operator can work in that section safely.

Industrial Customers Large industrial power users can utilize the benefits associated with medium voltage power factor correction and harmonic fi ltering. Medium voltage solutions usually support the scale and scope of larger services. Medium voltage applications can be found in the following types of industries as examples: automotives, pulp and paper, plastics, petrochemical, and heavy manufacturing. Individual fixed capacitors provide power factor correction directly at the cause of the problem, such as a large horsepower MV motor. Medium voltage systems allow large industrials to correct power factor at or close to the point of common coupling (PCC), where the utility electrical system meets theirs. This allows correction for an entire facility, instead of having to correct at multiple locations. The Cutler-Hammer NEMA  3R design also allows the system to be placed outdoors, saving valuable manufacturing floor space. The savings can be enormous, in materials, installation costs and floor space. In short, medium voltage solutions provide a cost-effective alternative to many local low voltage power factor correction units, while protecting the customer’s entire electrical distribution system.

Ease of Maintenance All components are front-accessibl front-accessible, e, facilitating routine inspection or parts replacement. A viewing window is standard on all compartment doors.

Flexibility Systems are expandable. The customer can add stages in the future by connecting the phase bus in the field via splice kits. Structures can be bolted together in the field.

Commercial Customers Many commercial customers are purchasing power from their utility at higher voltages today (2.4 kV – 15 kV), and can also take advantage of medium voltage power factor correction systems. These solutions can meet the needs of large office complexes, hospitals and universities, among others. The benefits of safety (key interlocking, no exposed live parts, etc.), and aesthetics (low profile, can be painted to match environment) both meet the needs of these applications where there are large numbers of untrained personnel in proximity of electrical equipment.

Ground Switch

Vacuum Contactors

A ground switch is provided to ground the load-side terminals of the incoming switch (or MLO) for safety during maintenance. Optional controls are available to permit closing contactors after the grounding switch has been closed to ground capacitors immediately (rather than waiting five (5) minutes for full discharge).

The type SL and SJ power contactors were designed and engineered specifically for use in AMPGARD  starters. They are self-supporting, compact, three-pole vacuum contactors. The SL contactor utilizes a solid-state control board, allowing the user maximum flexibility to change control voltages and dropout times in the field simply by adjusting DIP switch settings. The SL contactor is available for 2.4 kV – 4.8 kV volts at ratings of 200 and 400 amperes (the highest rated 400 ampere contactor available), and contactor interruption ratings of 8500 amperes allowing for higher levels of coordination with power fuses.

Ground Switch in the Incoming Section

Vacuum Switches On multi-stage capacitor systems, each stage is controlled by low maintenance vacuum contactors (2.4 – 7.2 kV) or vacuum switches (7.2 – 15 kV) depending on the application (see below).

5 kV Switched Capacitor Stage Enclosure

Individual Capacitor Fusing Each capacitor is externally fused with current limiting fuses. Fuses are equipped with blown fuse indication. Internally fused capacitors are also available as an option.

Thermal controls: Thermostats are included as standard to help maintain an acceptable internal environment for all components. Space heaters: Space heaters are provided to control moisture and humidity inside all enclosures. Each compartment has individual thermostats for fan and space heater controls.


Capacitors

Blown Fuse Detection System

Low loss, double-bushing capacitors that meet or exceed IEC 871, IEEE Std. 18 and CSA standards are supplied. Capacitors are connected in an ungrounded wye as standard, but can be connected delta as well. The dielectric fluid is environmentally friendly, biodegradable, non-PCB. Capacitor units are equipped with internal discharge resistors which reduce the residual voltage to less than 50 volts within 5 minutes of de-energization.

A visual pop-up blown fuse detection system is provided as standard.

Control Power Transformer A fused control power transformer rated for 1.5 kVA is provided for protection, control and operation of the capacitor or harmonic filter system.

Transient Voltage Surge Suppression A TVSS unit is supplied standard for protection of all low voltage controls in the system.

Harmonic Filtering Eaton’s Cutler-Hammer medium voltage harmonic fi lter systems are designed for industrial, utility and commercial power systems to improve power factor, reduce harmonic distortion, increase system capacity and reduce I2R losses. The reactors are typically tuned to the 4.7th harmonic, to mitigate the most damaging 5th level harmonic. This is the most common harmonic produced by six pulse variable speed drives. These filters are designed to the unique specifications of each electrical distribution system. Medium voltage capacitor banks can also be configured with de-tuned harmonic filters, typically set to the 4.2nd harmonic. This helps avoid harmonic resonance problems, provides harmonic filtering, and avoids the overloading that is possible with an improperly applied filter.

CPT and TVSS Provide Power and Protection for Control Section

Control Panel A door-in-door NEMA 3R swing-out control panel is provided on the main incoming structure as standard. This unit includes a viewing window so that all controls and information can be viewed without opening the panel.

Solid-State Controller Automatic metal-enclosed capacitors and harmonic filter systems come equipped with an automatic controller that switches each capacitor stage based upon power factor. The customer simply programs in the target PF to meet. The controller analyzes current PF, the size of each stage, and turns on and off stages to meet the customer’s programmed target. The controller has alarms such as power factor out of range, high harmonic voltage content and loss of power. Up to 12 steps of capacitance can be designed into any system. Customers can note this feature when designing for future expansions.
