Insights
Technical articles from Invitrona Engineering: how the equipment works, what affects its selection and which questions to ask before you specify.
Voltage Regulation & Power Quality
Servo and static voltage stabilizers: where each fits
How servo and static voltage stabilizers correct voltage, how they differ in speed, maintenance and rating, and which duties suit each.
Sizing servo voltage stabilizers for a multi-site rollout
How to size servo voltage stabilizers consistently across many sites: site load, recorded incoming voltage, deliberate margin and a small set of rating bands.
What voltage fluctuation does to equipment
How undervoltage, overvoltage, dips and phase imbalance affect motors, electronics, lighting and heating loads, and what to measure before choosing a correction method.
Transformers & Power Distribution
Dry-type and oil-immersed distribution transformers
How dry-type and oil-immersed distribution transformers differ in insulation, cooling, siting, maintenance and losses, and the project conditions that point to each.
Reading a transformer nameplate
What each field on a distribution transformer nameplate means, from rating and voltages to vector group, impedance, tappings and cooling, and why each matters on site.
Transformer losses and their energy cost
How no-load and load losses arise in a distribution transformer, how to turn them into an annual energy figure, and why the loss level belongs in the specification.
Rectification & DC Power Systems
Industrial rectifier basics: ripple, regulation and cooling
How an industrial rectifier converts AC to DC, what ripple and regulation mean for the process, and how air and oil cooling suit different ratings and environments.
Protecting DC loads: fuses, interlocks and earth faults
How DC systems fed by industrial rectifiers are protected: DC-rated fuses and breakers, semiconductor fuses, interlocks and earth-fault detection.
Selecting a rectifier for plating and electrolysis
The process, electrical and site information that decides a rectifier for electroplating, anodising and electrolysis, and the common sizing mistakes to avoid.
Power Supplies & LED Drivers
Constant-current and constant-voltage LED drivers
How constant-current and constant-voltage LED drivers work, which LED loads each suits, and the data needed to match a driver to a module or strip.
Questions for a power-supply supplier before validation
What an OEM should settle with a power-supply or LED-driver supplier before committing to validation: electrical fit, mechanical fit, compliance, production control and lifecycle.
Thermal design and derating in enclosed power supplies
How heat limits the output and life of an enclosed power supply or LED driver, how to read a derating curve, and what to check when the unit sits inside a product.
