1. POWER FAILURES

CAUSE BY :

- Power line downed- Lightning strikes- Grid over demand- Natural disaster

A total loss of powerEFFECTS :

- Hardware damage- Data loss- Force shutdown


Slide 4 04/09/23

2. POWER SAG

Short term low voltage

EFFECTS :

- System halts/crash- Loss of data- Hardware damage

CAUSE BY :

- Trigger by the startup large load ( eg: from Air Condition ) - Utility switching


Slide 5 04/09/23

3. POWER SURGE (SPIKE)

Short term high voltage above 110% of nominal

EFFECTS :

- Loss of data- Hardware damage

CAUSE BY :

- Lightning strike


Slide 6 04/09/23

4. UNDER VOLTAGE (BROWNOUT)

Reduced line voltage for few seconds/minutes/days

EFFECTS :

- System halts/crash.- Loss of data- Hardware damage

CAUSE BY :

- Intentionally utility voltage reduction- Heavy loads that exceed supply capacity.


Slide 7 04/09/23

5. OVER VOLTAGE

Reduced line voltage for extended periods of a few minutes/days

EFFECTS :


CAUSE BY :

- Rapid reduction in power load- Heavy equipment turn off- Utility switching


Slide 8 04/09/23

6. ELECTRICAL LINE NOISE

High frequency waveform caused by RFI/EMI interference

EFFECTS :


CAUSE BY :

- Transmitters (radio)- Welding devices- Ineffective grounding


Slide 9 04/09/23

7. SWITCHING TRANSIENT

Instantaneous under voltage in nanoseconds

EFFECTS :

- Hardware damage

CAUSE BY :

- Variable speed drives by electrical equipments


Slide 10 04/09/23

9. HARMONIC DISTORTION

EFFECTS :

- Communication errors- Overheating- Hardware damage

CAUSE BY :

- Non linear loads (ex: copier, fax machines)

Distortion of the normal line waveform

HOW TO SOLVE POWER PROBLEM

generator how generator works ?

Weaknesses :

- Voltage and frequency variations- Takes time to stabilize before passing the electricity- Regular maintenance


Slide 12 04/09/23


AVR (Automatic

Voltage Regulator)

Specification :

-170 to 250 Vac only

Weaknesses :

What if < 170 Vac ?What if > 250 Vac ?


Slide 13 04/09/23


UPS ( Uninterruptible Power Supply )

Specification :

- Combination of Generator + AVR function.

POWER BASIC

UPS SIZING ( if u know VA )

VA = voltage x ampere= 240V x 5amp= 1,200VA / 1.2kVA

UPS > 1.2kVA


Slide 17 04/09/23

POWER BASIC

UPS SIZING ( if you know Watt )

VA = 700 Watt / pf= 700 / 0.7= 1,000VA / 1 kVA

UPS > 1 kVA


Slide 18 04/09/23

EXAMPLES – SIZING UPS

IT EQUIPMENTS CURRENT UPS

PC – ACER M1800 3.15 Amp 756 V

Server – HP Z400 6 Amp 1,440 V

LAN Switch – HP Pro Curve 3500yl 24

0.6 Amp 144 V

Gigabit Switch – HP Pro Curve 3500yl 48G

5 Amp 1,200 V

Gigabit Swich + PoE – HP Pro Curve 3500yl 48G+PoE

3.3 Amp + 398W 1,361 V


Slide 19 04/09/23

VA

While UPSs aregenerally measuredin VA . . .

Watts

. . . The true outputpower of a UPS is

measured in watts

POWER DENSITY


Slide 20 04/09/23

POWER FACTOR

Power factor is the ratio of watts to VA:

Apparent power to Real power. VA

(apparent)Watts(real)

eg: 10kVA UPS

If pf 0.6 10kVA / 6kW pf 0.7 10kVA / 7kW pf 0.9 10kVA / 9kW


Slide 21 04/09/23

WHY POWERWARE IS THE BEST ?

• ABM (Advance Battery Management)

• Power Management Software

• Power Density

• X Slot Connectivity Option


Slide 22 04/09/23

ABM – ADVANCE BATTERY MGMT

Charger

Like other UPSs, the Powerware UPS is equipped with a charger that charges the battery.

However, Powerware uses a unique charging technique that extends the life of the battery . . .


Slide 23 04/09/23


ABM uses a 3-stagecharging system:

First, the battery is quickly charged to 90% to make surethe UPS is prepared for thenext power outage.

Second, ABM finishescharging the battery witha more moderate float charge.

Charger

Charger

Third, ABM turns the charger off.

This prevents the batteriesfrom being overcharged.

Feature Focus:

Turning the charger OFF


Slide 25 04/09/23

The Result?

The service life of the batteries is doubled so youwon’t have to replace them as often as you would with competitive models.



Slide 26 04/09/23

• Doubles battery service life by charging only when needed

• Optimizes recharge time

• Does not trickle charge & starve the electrolyte

• Microprocessor controlled - Only true & automatic battery check (periodic, controlled discharge) for most accurate advanced failure protection

• Sleep Feature - no unnecessary battery “drain”

ABM – ADVANCE BATTERY MANAGEMENT
