Recommendation of Swedish uninterruptible power supply for mining

What are uninterruptible power supplies (UPS)?

Uninterruptible Power Supplies (UPS) provide domestic and commercial customers with battery backup for their electronic devices, protecting against power surges or outages which could cause frustration, lost earnings and the need for costly equipment repair or replacement.

Can uninterruptible power supplies be used as a hybrid storage system?

Uninterruptible Power Supplies with hybrid storage system Uninterruptible power supplies with batteries as storage source provides good performance during grid interruption and blackout by suppling instant backup energy. However batteries cannot provide backup for a very long period of time and have limited charge/discharge cycles.

Who needs uninterruptible power supply?

Companies and socially critical organisations in certain areas have a requirement for uninterruptible power supply. Hospitals are an example where ensuring uninterruptible power is more important than anything else. Equipment must not be exposed to power outages.

What is uninterruptible power?

In larger installations, uninterruptible power is much more than a small-scale battery UPS that keeps an alarm system running for an hour or two despite a power cut. Redundancy in the form of backup power systems is not uncommon when the need is greater.

Can Bravida handle uninterruptible power supply?

Bravida has both small and large-scale expertise that can handle uninterruptible power supply for more extensive needs. Safe and uninterruptible solutions require analysis, planning, design, installation and operational monitoring. This is part of our everyday life and not something we take for granted.

What is the minimum power factor for UPS?

According to the IEEE standard ANSI/IEEE 446–1987, minimum power factor is 0.8 at the rated load and harmonics content less than 5% is preferred for the input rectifier of the UPS system. Table 8. Typical 3-Ø UPS System Specification by ANSI/IEEE 446–1987 . Fig. 27. Input Voltage and Current waveform.
