power, it is a consulting team that was born to present the direction of real electricity rate reduction.

• The first step towards saving electricity costs starts with measuring power quality.

• The main advantage of the solution presented by JAGUAR IoT Team is accessibility.

For convenient management of users, it is a product with built-in web server it is the best product for consulting.

• AC power and DC power measurement, ESS-optimized branch circuit monitoring with solar home and electric car

charger when building a cloud separately, the built-in web server capabilities are ideal for smart factories because

it helps to reduce cloud server management costs.

• The JAGUAR IoT Team measures transformer harmonics and leakage currents for high and low pressure customers

during a three month free diagnosis period measuring and analyzing the real-time power consumption of the

facilities used, or establish future measures to provide a reasonable solution.

03The need for power quality measurement

The quality of the power is determined based on factors such as "instantaneous voltage drop", "harmonics", and "disturbance" depending on the fluctuating nature of the voltage, the most important of these is harmonics.

<Harmonic generation scheme>

8

Harmonics are frequencies with an integer multiple of the fundamental frequency, with frequencies below 50th order, and higher frequencies are classified as high frequencies. When these harmonics occur, the waveform of the power system is distorted, which seriously affects the power equipment and the line.


Harmonics are generated mainly by nonlinear loads (electronic fluorescent lamps, LED lights, inverters, uninterruptible power supplies, etc.), distorting the voltage of the power supply system and causing excessive current to flow in the phase capacitor, generator, overheating or loss may occur.

9

<Harmonic generation scheme>


Worldwide, in 2008, we established and specified power quality

measurement standards in accordance with IEC 61000-4-30, and

since 2009, we have established harmonic management

standards for power distribution systems in Korea.

10

These regulations are being applied together when KEPCO

establishes contracts with power consumers, and is an

important consideration for high-voltage consumers, especially

those with high power such as production automation plants. In

addition, since the measurement of power quality is related to

each other such as power supply and power usage of each load,

it is necessary to measure power quality by including power

energy management in power quality management.


11

J & D has developed the JAGUAR 6300S, a power quality meter

that meets IEC 61000-4-30, as a solution to this problem. It also

has a high-quality, high-precision current sensor, AC / DC

current sensor, Sensors, etc., and provide them as PQ-CT and

PQ-VT brands.

In particular, as the Electricity Business Act was amended in July

2015, a power quality analyzer was added as a common

equipment that electric safety managers must have as a

necessity. JAGUAR IoT TEAM, therefore, proposes a high-

performance power quality analyzer to enable more accurate

and efficient electrical safety management.

2

04The need for DC power measurement

12

1 3Most power networks in Korea as

well as globally are made up of

AC (alternating current)

distribution, so there was less

demand for DC (direct current)

distribution. Recently, however,

DC distribution has been

receiving a lot of attention

because it is easy to link with

distributed power system and it

is possible to make long distance

transmission with low loss.

In particular, demand for DC

distribution such as

renewable power generation,

electric car charger, and ESS

(energy storage device) is

increasing, and according to

the EPRI report, there is.

There is a need for a watt-hour

meter to measure DC power, but

there are few technical standards

and testing facilities around the

world. However, J & D developed

the JAGUAR 1000D, a DC watt hour

meter, in preparation for the

completion of the IEC standard

currently being enacted. Once the

IEC standard is successfully finalized,

J & D Electronics can become a

leading technology company in this

field will.

Czech Republic KMB system s.r.o – NOVAR series Automatic Power Factor Controller

• As KEPCO's power-factor pricing system has changed, there is a need to take measures

against the true power factor ¹

• As the ground power factor ² also increases the supply capacity, the true phase power

factor also causes the harmonic expansion phenomenon along with the increase of the

power factor due to the ferrite phenomenon.

• At nighttime, the transformer is over-excited by the rise of the load voltage, and the

voltage of the harmonics of the system is increased, and the load of the transformer is

short-circuited for the purpose of power reduction, so that the lower harmonics resonate

with the capacitor to increase the harmonic voltage. . This problem requires that the true

power factor be more strictly controlled than the ground power factor.

Need for Automatic Power Factor Controller

¹ : The power factor when the current phase

is ahead of the voltage phase

² : The power factor when the current phase

lies behind the voltage phase

³ : The phenomenon that the lead voltage

becomes higher than the power supply

• Procedure • Success stories

The contract power of the first level was designed for the newly built buildings of 2

floors underground and 8 floors above ground in Jung-gu, Seoul. At this time, the

design capacity was calculated by applying the capacity of 65% of the total load

capacity. As a result, the contract power of 85 kW was selected and contracted to the

safety manager under the Electricity Business Act.

However, the eGauge meter, which is a multi-channel energy meter of JAGUAR IoT

Team, was installed and analyzed the power data for one year. As a result, it was

confirmed that the maximum power consumption of this customer did not exceed

55kW.

Taking into consideration the margin, we selected the electric power again with the

capacity of 65kW, This allowed us to reduce our overall energy management costs by

eliminating the need to deploy safety managers as well as our base rate reductions.

: Look for the right contract power
