Magney Grande offers specialized services and products in transient surge suppression, power quality and engineering consulting for marine, air station, oil production and drilling, and general industrial applications.

Their expertise in the field of power quality has led to the development of the following useful products to mitigate ESP electrical problems:

Ziton

Ziton is a standalone voltage and current monitor for all 3 phases. It is available for Medium Voltage (up to 5000V) and Low Voltage (480V). To our knowledge, there is no true ESP voltage or current measurement device available. Presently, the voltage of the surface to the motor is calculated by inputting the turns ratio of the step-up transformer and the current of the motor is derived from the running current of the Variable Frequency Drive (VFD). Ziton is connected to the MV taps of the step-up transformer with 3 phase voltage leads, a ground lead and 3 phase current transformers. Voltage is at a 100:1 ratio and current transformers are at a 200:5 ratio. Connection to the digital display comes from the input lugs to the 480V VFD. This ensures that the display is active during a manual shutdown of the VFD. Ziton will monitor voltage and frequency during backspin of a PMM motor, which is an industry safety concern. Ziton also displays Power Factor, KW, KVA and KWH along with real time motor voltage (supply voltage at the surface) and current. Ziton is also equipped with a modbus protocol RJ45 connection for use in Producers SCADA system. Ziton is the only technology known to have these capabilities. It also has analog access points for voltage and current on all 3 phases using a standard fluke meter.

With Ziton, producers can ensure the ESP is finished with backspin and it is safe to enter the MV cabinet to perform any service work. Producers can optimize voltage to the motor and know if SUT taps are actually providing the voltage listed on the nameplate. Ziton helps to mitigate arc flash exposure to field personnel. This technology can provide indicators to the producer, which can help them to power the ESP to minimize slip and lower motor temperatures.

Hundreds of units have been successfully installed in the Permian Basin since 2023.

Common Mode Filter (CMF™)

The CMF™ is a patented product that was commercialized in 2017 and is used to protect electrical submersible pump systems (AC Induction or Permanent Magnet Motor) being operated by Variable Frequency Drives. This equipment is applied at the output side of the step up transformer to mitigate harmful high frequency harmonics generated by the carrier frequency of the inverter of the VFD from going to the downhole equipment. This equipment was featured in World Oil in the What’s New in Artificial Lift section. The use of this device has resulted in the increased runlife of cable, penetrators, splices, MLE/pothead and motors both electrically and mechanically/bearing fluting.

Surge Protective Devices (SPDs)

The UL 1449 4th Edition Listed SPDs mitigate harmful transients from reaching the Electric Submersible Pumps and also protect the variable frequency drives from electrical damage due to lightning and switching events.

Enhanced grounding systems (chemical ground rods)

The grounding system provides the best possible ground in extreme environments. Low ground resistance is imperative for lightning protection systems to work properly and for equipment and personnel safety. A low ground resistance is also imperative for microprocessors to operate correctly and the ESP downhole gauge/sensor to establish data transmission.

Common Mode Filter (CMF™) Magney Grande developed the patented Common Mode Filter at the request of producers for the purpose of increasing VFD ESP operating system runtimes. Magney Grande is the only company that manufactures and markets the Common Mode Filter (CMF™).

The CMF™ has been designed to also serve as an early warning system for component degradation of the Sine Wave Filters in Variable Frequency Drives.

Ziton Field technicians and other personnel do not know when the ESP is finished with backspin and if it is safe to enter the MV cabinet to perform any service work. Producers are not necessarily able to optimize voltage to the motor and know if SUT taps are providing the voltage listed on the nameplate. Arc flash exposure to field personnel is extremely and sometime fatally dangerous. Other technology lacks indicators for the producer, which can help them to power the ESP to minimize slip and lower motor temperatures.

Common Mode Filter The industry problem in the operation of ESP systems is premature failure caused by harmful high frequency, high voltage transients and poor grounding. The high frequency harmonics cause damage to the first weak area in the ESP Electrical string and continues until the failure of the ESP. The damaged components include: cable, penetrators, splices, MLE/potheads, motor windings, thrust bearings and rotor bearing fluting.
