your electric bills vary?
is not always possible that your electric
bill will be the same every month. Varying
electric bills are usually the result
of the following factors, namely:
1. Addition of new appliance
" The additional electric consumption
of the new appliance will depend on
the unit's wattage rating and how much
use it is given.
Replacement of smaller appliances with
one bigger size capacity.
" For instance, replacing a 150
watt 6 cu. Ft. Refrigerator with a 200
watt 10 cu. Ft. durable type would mean
an increase in electric consumption.
Additional or longer use of smaller
" Additional people in the house
weather they are guest or staying relatives
could mean more cooking and longer use
of electric stove or children who came
from school could mean more TV viewing,
more ironing, more lighting, longer
use of electric fans, which will all
lead to increase electric consumption.
Also, the weather and the season brings
about a considerable difference in your
consumption is air conditioners and
refrigerators work harder and longer
in the summer months.
Faulty and/or grounded wires and appliances
" Wires are protected by rubber
insulation but when this insulation
is cut or torn exposing the wire inside,
this not only poses as fire and safety
hazard but also wastes electricity.
When the bare wire gets in contact with
objects that conduct electricity, this
results in electricity leakage, a condition
commonly called "grounded."
Electricity leakage adds to your consumption
in same manner that a leaking water
pipe or dripping faucet adds to your
water bill. Faulty appliance such as
refrigerator could run for prolonged
periods because of defective thermostat,
and so waste electricity. A fluorescent
lamp with a defective starter does not
light immediately when you switch on,
but make several flashes before it finally
lights up. This problem wastes electricity
as half of the fluorescent electric
consumption is used when it lights up.
Consult your electrician or appliance
technician and have your grounded wires
and faulty appliances connected immediately.
5. Meter reading problems
" An incorrect reading could be
made specially if the meter is located
where it is difficult to read such as
if it's been installed it high, the
meter glass covered with thick and hardened
dust, or building extension has partially
covered the view of the meter. As much
as possible, the meter must be facing
the street, clean of obstruction, and
installed not more than 6-ft. high.
Our meter reading system has cumulative
feature that ensures that any meter
reading error committed is automatically
covered up in the subsequent months
reading. Thus, an over reading this
month normally results in a lower electric
consumption in the following month and
under-reading this month result in a
bigger electric consumption in the following
month. As adjustment is made to your
account when an incorrect reading is
Longer than normal belling periods
" Meter readings are scheduled
in such a way that billing period is
cover more or less a month, or 30 days.
However, it is not always possible for
the meter reader to come exactly on
the same day each month because of sickness,
holidays or bad weathers. The period
covered and the number of days indicated
on your electric bill. Compare this
with your previous bills as it might
have cause a slightly higher bill this
7. Meter registration
" The electric meter is precise
instrument and has been tested, calibrated
before it is issued to its member-consumers.
However it you fill that the meter is
faulty, you may request for a meter
test by informing ISECO personally or
8. Increase in electric rates
" You may have maintained the same
level pf kilowatt-hour, but the amount
you pay for it higher when electric
rate increase. Adjustments in rates
are dependent on its variable and fixed
" Generally, electric consumption
varies among household depending on
the standard of living habits, family
size and needs. So that, it is NOT POSSIBLE
to compare your electric bill within
that of your neighbor.
about brown outs including causes of power
NPC Power Plant Shutdown
NPC which is the sole power supplier of
the coop may cut off power due to either
of the following: repairs in the geothermal
plant, replacement o poles of insulators
and rehabilitation/repair of lines. Brown-out
caused by these factors are scheduled
with NPC officially notifying the Coop
who in turn notifies the consuming public.
In cases, where power failures are caused
by natural calamities such as typhoons,
earthquakes, floods, etc. no notices are
sent by NPC; hence, the Cooperative could
not sent any to be the consumer.
2. Sub-Station Repairs and Maintenance
The coop schedule brown-outs when repairs
and maintenance are to be made in the
Sub-Station. This includes among others;
the changing or filtering of the sub-station
transformer oil as well as that of the
recluse's, replacement of burned instrument
transformer and the tightening/checking
of terminal connections.
3. Line Repair and Maintenance
To prevent accident, electric power must
be cut off when linemen do repair works
such as: changing rotten poles, replacing
broken insulators and clearing of transmission
or distribution lines and other.
4. Line Faults or Tripping
Line faults occur when objects come in
contact with the power lines. Two common
types of faults are: short circuited or
line-to-line fault and grounded line or
line-to-ground fault. Common causes of
line faults are: trees touching power
lines, broken insulators, live wires in
contact with the ground.
5. Transformer Trip Off
Most of the distribution transformers
used by the Electric Cooperatives are
equipped with built-in-tripping device
or circuit breakers. This device automatically
cuts off power to the area supplied when
the transformer loaded beyond its capacity,
or when line faults along secondary lines.
6. Fuse Blow-out in your Fuse Box
When lights go off in your house but those
of your neighbor's are still on, it might
be that fuses in your fuse box have burned
out. There are two common causes of fuse
blow-outs namely: short circuited connection
and excessive loads.
Tips during brownout
Always unplug electric appliances in case
a brown-out occurs. If the power is restored,
always give an allowance of 2 to 3 minutes
before plugging in appliances, especially
those driven by electric motors such as
refrigerators, electric fans and compressors.
This is to save energy and prevent damage
to appliances due to the sudden surge
of current when power is restored.
2. If you encounter a wire-down during
brown-outs, never touch it. Treat the
wire as a "live" wire and report
to the nearest ISECO office for immediate
repair. Never take chances when working
with electrical appliances and equipment
even though there is a brown-out before
working with them. This will protect you
when power is restored anytime.
to do during brown-outs due to blown-out
your lights go off, don't panic nor curse
the darkness. First, check whether your
neighbor's lights are on. Chances are,
you probably have blown-out fuse. If so,
1. Keep a flashlight handy and find the
main service switch. It usually located
near the area where your service drop
or line enters your house/building.
2. Switch off or pull down the switch
3. Open switch box. Remove blow-out fuses
with a repair of insulted pliers. With
the burnt out marks or traces on their
metal parts, you can easily identify the
4. If you're familiar with the amperage
of your fuses, bring them along with you
purchase with your replacements.
5. Install replacement fuses securely.
6. Close the switch box and switch on
or push up the switch level.
7. If all else fail, summon professional
recognize the existence of trouble in
an electric system you should be able
to recognize the symptom. The following
are the most common:
1. No voltage - if he circuit is dead,
the cause may be blown out fuse, a loose
connection, or a broken wire. It might
also be failure of the transfer.
2. Fuse Keeps Blowing Out- This may be
caused by an overload, that is, too many
appliances are connected to the circuit,
thus drawing too much current more than
the capacity of the fuse. It may also
be caused by a short circuit, which is
power touching the ground, or two power
wires in contact. DANGER: DO NOT TRY
TO REPLACE THE FUSE WITH A BIGGER SIZE
OR SOLID WIRE. IT MAY CAUSE AN ELECTRICAL
3. Lights Burn Brightly, But Bur Out.
This usually means that the voltage is
too high. Either a generator is not regulated
properly or a transformer is properly
4. Connections Get Hot. This usually means
that the connection is loose, thus creating
high resistance. All electrical connections
must be very tight and solid.
5. Shocks When Touching Equipment. This
symptom indicates that the equipment or
motor has not been properly grounded.
Voltage Fluctuations.This usually happens
when a consumer which is tapped in a common
secondary line is utilizing an equipment
with big power requirement, such as welding
machines, industrial motors, big electric
oven, etc. which, when operated will draw
a big amount and thus causing a responding
voltage drop of the big amount and thus
causing a corresponding voltage drop of
the common secondary line.
If you experience these troubles, call
the attention of your electrician or your
nearest ISECO Office.
