Industrial Manufacturing

Surge loads, rough grids, continuous output

Context

Start from the real problem

Line power problems often show up as occasional stops and equipment misoperation. Measure load surges and grid quality before specifying.

01

Large inrush

Welders, moulding machines and large motors cause voltage dips.

02

Harsh environment

Heat, dust and oil mist demand more from enclosures and cooling.

03

Costly downtime

One unplanned stop can scrap a whole batch.

How the power chain is built

01

Load tiering

Separate control systems from motive loads.

02

UPS selection

Line-frequency isolation preferred for surge loads.

03

Distribution

Maintenance bypass designed alongside zoned distribution.

04

Site fit

Enclosure and cooling customised to the workshop.

Project considerations

Load profile
Measure inrush current and duration.
Grid quality
Deviation and harmonics drive input design.
Environment
Temperature, dust and corrosion affect the enclosure.
Serviceability
Access and lifting conditions confirmed at design stage.

Welding shop control supply retrofit (illustrative)

Separating control protection from welder power reduced the effect of welding voltage dips.
