NEPSI

The Most Trusted Name in Power Factor Correction and Harmonic Filtering

PRODUCTS


Northeast Power Systems, Inc. (NEPSI) manufactures various medium voltage metal-enclosed products to mitigate common power quality concerns. Review NEPSI's product offering below to determine what product(s) you need. Feel free to contact NEPSI for technical assistance.

Power Factor Correction



Capacitor Banks    |    Harmonic Filters

Metal-enclosed power capacitor banks and harmonic filter banks correct for poor power factor. Consider shunt power capacitor banks if your system does not have a resonance concern and significant harmonic producing loads. If harmonic resonance is a concern, or if you require harmonic attenuation, you should consider harmonic filters.

Harmonic Mitigation and Power Factor Correction



Harmonic Filter Banks

Metal-enclosed harmonic filter banks reduce harmonic voltage distortion, harmonic current distortion, and improve power factor. Consider this product if you have resonance concerns or significant harmonic producing devices on your system and you need power factor correction.

Voltage Sag & VOLTAGE FLICKER Mitigation



Thyristor Switched HARMONIC Filter Banks

Consider a Thyristor Switched Harmonic Filter Bank when instantaneous var support is need to mitigate voltage sags, voltage flicker, and high inrush currents associated with starting and impact loading of large motors and dynamic loads. This equipment stabilizes your system voltage, helps your equipment run more smoothly, and increases your systems efficiency and throughput.

Hybid designs that include conventionally switched harmonic filters for power factor correction and harmonic attenuation are also available.

Surge Protection



MV-TVSS    |    RC Snubbers    |    MSP

NEPSI's offers various surge protection products. Consider the MV-TVSS (medium-voltage transient voltage surge suppressor) product offering if you are looking to protect your service entrance from system transients. The MSP (Motor Surge Protector) is designed for placement near motors to protect motor windings from system surges. RC Snubbers are designed to protect potential transformers and power transformers from ferroresonance produced by switching transients associated with opening and closing of nearby vacuum circuit breakers.
