A colloid mill can reduce and smooth pre-hydrated oat solids in a spread, but it won’t realistically replace a chocolate refiner/ball mill/3-roll if you need true «chocolate-smooth» fineness. In practice for your mix (oats + date juice + cocoa + hazelnuts + cocoa butter), a rotor-stator colloid mill typically delivers a stable, creamy texture in the tens of microns, and ~20-50 µm is a realistic range after good pre-milling + recirculation. Getting <10-15 µm across the bulk is usually not practical with a colloid mill alone, especially with fibrous oat particles and a high-viscosity fat phase-heat build-up and fiber limits become the bottleneck. If your target is the "premium chocolate spread" mouthfeel (often perceived when most particles are <25-30 µm, and many products aim lower), consider: pre-hydrating oats, using the colloid mill as a pre-refiner, then finishing with a ball mill or chocolate refiner; or skip the oats grind by using oat flour/enzymatically treated oats so you're not trying to micronize fiber.

A step-up transformer increases voltage but does not increase total power. As voltage increases, current decreases so that real power remains approximately constant, minus losses. Utilities use step-up transformers at power plants to raise voltage for long-distance transmission, reducing I²R losses in conductors.

When faults such as winding failure, bushing flashover, or oil ignition occur, protective relays trip breakers to isolate the transformer. This removes sections of the network, causing outages until repairs or switching restore service.

Storage requires dry, temperature-controlled conditions, sealed nitrogen or oil-filled tanks, periodic desiccant checks, and preservation of bushings and gaskets to prevent moisture ingress.

Layer, disc, helical, and continuous windings; primary/secondary arranged for insulation and fault withstand.

Grid transformers are primarily designed and tested according to IEC 60076 series (IEC markets) or IEEE/ANSI C57 series (North America). Additional standards include ISO quality frameworks, environmental regulations, regional grid codes, and utility-specific specifications for seismic, overload, sound level, efficiency, and monitoring. Compliance ensures interchangeability, safety, dielectric coordination, thermal limits, and performance under short-circuit and transient conditions typical of transmission and distribution systems.

Bushings provide insulated current-carrying pathways from internal windings to external connections, preventing surface tracking and flashover at high voltage.

The CMM-0.6L is a compact transformer oil purification cart (600 L/h), while BDV testing is performed with TOR-series instruments (TOR-80 or TOR-100). We will provide pricing and technical documentation for both options.

It removes moisture, gases, and solid contaminants from transformer oil. GlobeCore’s machines are used by utilities worldwide to restore dielectric strength, prevent insulation failure, and extend equipment life.

It measures the voltage at which oil breaks down electrically. Low BDV = high failure risk. GlobeCore dehydration and filtration equipment restores BDV, keeping your transformer within safety thresholds.
