• Power problems

Power supply problems are caused by various sources, for example distribution network faults, system switching, weather and environmental conditions, heavy plant and equipment or simply just faulty hardware. Regardless of the cause of the problem, the result will include one or more of the following types of power problems:

• Sags

Are short duration decreases in the mains supply voltage which generally last for several cycles. They are one of the more common forms of disturbances. When sags occur sensitive equipment can lock or hang causing data loss and system resets.

• Surges

Surges are short duration increases in the mains supply voltage which generally last several cycles. When surges occur equipment can suffer from premature failure. The high voltage causes wear and tear and general component degradation. This may not be noticeable until failure, though heat out is a good sign.

• Transients and Spikes

Transients and Spikes these are very fast high energy surges lasting only a few milliseconds. When transients or spikes occur equipment can lock or hang, crash and even suffer damage which inevitably causes data loss and corruption. Large transients can occur from local or worst case a direct lightning strike.

• Electrical Noise

Electrical Noise this is a high frequency noise either common or normal mode which can cause severe disruption and damage to circuits and equipment.

• Power Protection Solutions

• Power problems

Power problems cause voice and data processing errors, hardware damage and expensive downtime. When an Uninterruptible Power Supply (UPS) as your power protection solution it is important to consider two elements:

1.  How clean is my mains supply when it is present?
2. Does the application need to be kept running when the mains fluctuates wildly or fails and if so for how long?

Power Quality without battery back-up : Solutions vary in the power quality they provide and include:

• Filters

A filter will attenuate spikes and electrical noise down to predefined levels. A very basic economic form of power protection.

• Transient Voltage Surge Suppressors (TVSS)

A TVSS will clamp and divert the excess electrical energy of transients away from downstream loads. A TVSS is superior to a filter and can cope with lightning strike surges in some instances. They are commonly used within heavy industrial complexes and mobile base stations. When placed before Uninterruptible Power Supplies a TVSS will provide protection for the Uninterruptible Power Supply itself from local transient surges.

• Voltage Stabilizers

Smooth out sags, surges and brownouts in an attempt to provide a near stable supply and are typically used in combination with a filter. They provide a form of power protection used typically in third world countries for non-critical loads such as fridges and freezers. A voltage stabilizer (also known as an Automatic Voltage Stabilizer or AVR) can be electronic or electro-mechanical.

• Power Conditioners

The ultimate power protection without battery backup. They can be either transformer or electronic based and provide conditioning in the form of filtering, stabilization and regulation. Some power conditioners can also provide Galvanic Isolation. This is more commonly associated with Constant Voltage Transformers (CVTs).

• Power Quality with battery backup – Uninterruptible Power Supplies (UPS)

There are three generic UPS types. These differ in the power quality they can provide when the mains is present, the battery runtime they can provide, the type of output waveform they provide when running on mains and how smoothly or not they transfer between the mains and battery supplies:

1. On-line UPS (also known as double-conversion) – the ultimate power protection.
2. Line Interactive UPS – intermediate level protection.
3. Standby UPS – entry level protection.

• Batteries

Different range of Batteries, which are extensively used for various applications are in Clinics, Hospitals, Home, Offices etc. These batteries are sourced from reliable vendors to ensure optimum quality and effective operations in various applications. Mainly using the power conditioning applications of batteries such as:

• Tubular Batteries

The performance rate of tubular batteries is very high and also has best resistance against corrosion. Their life is very long and does not get easily damaged.  Today tubular batteries are most advanced known batteries. These batteries are not getting discharged very soon. These tubular batteries are available in different shapes and designs in the market.

• VRLA (Valve regulated-lead acid) /SMF (Sealed Maintenance Free) Battery.

This battery finds their importance in many ways they have high recovery for discharge. There is no leakage in these batteries because they are constructed in such good manner. These batteries require the addition of acids to the cells instead of water. These batteries are generally employed in UPS. Their performance rate is very high and also has the capacity to resist against corrosion.
