Keywords: Distribution Systems, Electrical Distribution, Variable Frequency Drive

Through experience, we have determined the real-world requirements for reliable power systems in extremely harsh environments and have designed our Variable Speed Drives and Electrical Distribution Systems to exceed these operating parameters.

  • Electrical Submersible Pumps (ESPs)
  • Progressive Cavity Pumps (PCPs)
  • Sucker Rod Pumps (SRPs)
  • Industrial Horizontal Pump Systems (HPS)
  • Industrial Motor Drives for pumps, fans, and similar applications

EnerDrive AC drive HMI control systems use touch screens for low-temperature applications and LCD keypad for high-temperature applications. Our HMIs are intuitive and include all of the protective features normally associated with pump type applications such as;

  • Load related under and over current
  • Under and over voltage
  • External analog and external digital controls
  • Reverse rotation
  • True fundamental output voltage
  • Frequency and current leakage monitoring (optional)

Advanced features of EnerDrive VFD AC Drives’ include:

Meets IEEE Harmonics Standards

EnerDrive VFD systems configured with 12, 18, or 24 pulse front-end rectifiers are pre-configured at the factory to meet the final application design requirements. Load test may be performed on request to pre-determine performance.

VFD Enclosure Construction

Direct On Line (DOL) Bypass Feature

The EnerDrive DOL VFD bypass system is used when a fully redundant power system is required. The VFD bypass system contains switches and contactors that are engaged by a manual or motorized external selector switch. This allows motor power to selectively come from the Variable Frequency Drive or an across-the-line starter, reducing lost operating time.

Output Waveform Sinewave Filter (Optional)

EnerDrive AC drive systems may be specified with the EnerWave IEEE 519 standard compliant line, sinewave, or dv/dt filters. The ED-600 Series Sinewave Filter dissipates the high-frequency harmonics on the VFD output, so that the output then resembles a true sinewave. RESULT: lower insulation stress and longer motor-cable system run-life.

Transient Voltage Surge Suppressors (TVSS) (Optional)

A TVSS uses state-of-the-art MOV devices assembled in a non-destructive, fuse-protected NEMA 4 enclosure. The device may be mounted inside the Variable Speed Drive electrical enclosure without additional protective devices such as circuit breakers.

Benefits of Solar Powered Street Lighting

Reduced Damage/Theft – By locating the solar technology directly on the light ?xture and placing the battery within the light ?xture, the risk of damage, theft or tampering is greatly reduced. Since no electrical grid is required, it can be installed on buildings, in parking lots, in remote locations simply by hanging it on a pole. There are no wires in the street pole, which means that the wire itself can’t be stolen and sold for scrap.
