We measure first. Equipment comes after.
Every recommendation rests on data from your own electrical system, gathered before anything is installed and again after.
- Evaluation
- 1
First conversation
We review your utility bills and one-line diagram, and ask about your transformers, switchgear, motors, drives, HVAC, compressors and maintenance history.
- 2
Engineering site survey
An engineer walks your electrical rooms, checks panels, grounding, capacitor banks and filters, and talks to the people who maintain the equipment.
- 3
Power-quality measurement
Temporary meters record voltage, current, kW, kVA, kVAR, power factor, voltage and current harmonics, demand, imbalance and transients. The data defines the problem.
- 4
Engineering report
Current operating conditions, root causes, what they cost you, maintenance concerns and the equipment at risk, with recommendations.
- 5
Recommendation
Panel-level correction with Reinigen, facility-wide correction with MPTS, or other fixes where they fit better: grounding, load balancing, filters, metering or maintenance.
- Demonstration
- 6
Six-month rental
The recommended equipment goes in on a rental. The same measurements run, so before and after are compared on your own system.
- 7
Performance report
Measured changes in power factor, current, kVA, kVAR, demand, energy and harmonics, with payback and released capacity.

Your decision
Purchase, lease, keep renting, expand to more panels or buildings, act on other recommendations, or end the evaluation.
Why less current is the whole point.
Power factor, as a beer
The beer is the work you use. The foam does no work, but the utility still has to fill the whole mug, and your wires still have to carry it. Drag the slider, or pick a reading from the measured case.

At 0.87, 13% of everything the wires carry is foam. It fills the transformer and heats the cables, and some US utilities bill for it.
Drawn to scale for 100 kW of work: the foam is the extra kVA the wires carry (kVA − kW). The presets are the measured case’s average and lowest readings before correction, and its average after.
S² = P² + Q²
Apparent power (S, kVA) combines real power (P, kW), which does the work, with reactive power (Q, kVAR), which does not. Cut Q and S falls at the same real load, and with it the current.
PF = P ÷ S
Power factor is the share of apparent power doing real work. At 0.87, a panel carries about 15% more current than the same load would need at 1.00.
Loss = I²R
Losses in conductors and transformers grow with the square of current, so a 10% cut in current trims those losses by about 19%.

Drives, LED drivers and switch-mode power supplies draw current in pulses. The pulses add harmonic currents that raise RMS current, heat neutrals and transformers, and travel to equipment elsewhere on the same network.
