Compensating voltage dips
Conditioners support voltage within a defined envelope of residual voltage, duration and load. Suitability must be checked against recorded events; support during a complete interruption must not be assumed.
VOLTAGE STABILITY
Voltage dips and regulation
Short voltage dips and sustained supply levels outside the permitted range require different measures. Selection starts from recorded events and equipment sensitivity.
Regulating sustained variations
Stabilisers and regulators maintain voltage within their specified range, with response and limits determined by their technology. Input range, inrush and behaviour during fast events are selection criteria.
How Studio PQM helps
Correlation of events with stoppages, definition of the critical load and comparison of alternatives. The aim is protection suited to the process, with agreed verification criteria.
Compare ranges and features · 2 configurations
General guidance by solution type, using a 400 V low-voltage supply as reference. Ranges summarise the ratings considered and do not imply that all combinations are available. Connection, rating and actual performance must be checked for the project.
| Configuration | Ratings and supply | Features | Checks required |
|---|---|---|---|
| Voltage-dip conditioner | 150–3600 kVA; reference supply 400 V | Voltage support within system limits | Residual voltage, duration, load and complete interruptions |
| Continuous regulator | 250–3000 kVA; reference supply 400 V | Voltage regulation under the specified project conditions | Regulation range, load, response and inrush |
Compensation range, duration and overload capability must be checked for the selected model. Voltage-dip compensation does not imply the ability to supply the load during a complete interruption.
