01J&D Introduction

3

Since 1994, J&D has been pursuing continuous innovation for

more than 20 years, presenting a new chapter in the power

electronics industry and growing into a global company.

J&D Electronics has developed current sensors, voltage sensors,

smart meters, and quality meters, which are essential to the electric

devices in a wide range of industry, including renewable energy,

power transmission, distribution, solar power, and power energy

monitoring.

To become a global market leader by configuring JAGUAR IoT

TEAM for energy saving monitoring, we newly introduced high

precision current sensor PQ-CT and voltage sensor PQ-VT with

the Power quality meter JAGUAR brand.

02About JAGUAR IoT TEAM

JAGUAR IoT Team is a consulting team that was created to provide an optimal Demand power by analyzing

power usage characteristics for each site and thus provide a true direction for reducing electricity charges.

The first step to reducing electricity charge is measuring power quality.

The advantage of the JAGUAR IoT Team is accessibility.

For the convenience of users, JAGUAR IoT provides a free UI with built-in web servers, making it an excellent

choice for free diagnosis and consulting of facilities.

It is suitable for smart factory since it can save management cost of cloud server by built-in Web server; for

AC power and DC power monitoring and the optimal branch circuit monitoring for ESS (Energy storage

system) such as Solar home and Electric vehicle chargers.

JAGUAR IoT Team measures the harmonics and leakage currents for high and low voltage user's transformer and

analyses the real-time power energy consumption. It offers the reasonable solution by suggesting accurate standard

to establish the appropriate countermeasures for diagnosis or future.

JAGUAR IoT’s vision is to provide sustainable, dependable

and efficient energy usage by making energy management

more convenient and intelligent for the whole world.

JAGUAR IoT’s various power quality & metering devices

are designed for supporting with versatile options and

product range allowing users to manage and monitor the

distribution and usage of energy.

JAGUAR IoT products can be easily integrated into new or

existing energy monitoring systems, automation facilities

and building control systems for intelligent, cost-effective

energy systems that are supported by the expert

technical staff.

03The need for power quality measurement

The power quality is determined based on factors such as " momentary voltage drop ", " harmonic " and " disturbance " depending on the variable nature of the voltage. The most important factor is "harmonics".

<Harmonic generation scheme>

8

Harmonics are frequencies that have an integer number of the fundamental frequencies, which are known as harmonics in the order of 50 or less, and above which are classified as high frequencies. When these harmonics occur, the power system's waveforms are distorted, causing serious adverse effects on the electric equipment and the track.


Harmonics are mainly caused by nonlinear loads (e.g. electronic fluorescent lights, LED lights, inverter, uninterruptible power supply), which can distort the voltage of the power system and cause excessive temperature in the power condenser, generator, and lighting facilities, etc.

9

<Harmonic generation scheme>


In Worldwide, Power quality measurement standards are already

established in 2008 with IEC 61000-4-30 standards, and Korea

has established and implemented distribution system harmonics

management standards since 2009.

10

These regulations apply with the Korea Electric Power

Corporation when setting up demand power with the power

user, and they are an important consideration for high voltage

users, especially those that use large power such as Automated

production factory. Power quality management should naturally

include power energy management, as measurement of power

quality is related to each load, such as measuring power supply

and power usage.


11

For this solution, J&D has developed its own power quality

meter, JAGUAR 6300S, which meets the IEC 61000-4-30 and

offers PQ-CT and PQ-VT (high quality sensors, multiple AC/DC

current sensor, voltage sensor) which is suitable for use with

JAGUAR 6300s.

Especially, with the revision of the Electrical Business Act in July

2015, the Power Quality Analyzer has been added as a

necessary common equipment for the safety managers. For this

response, JAGUAR IoT TEAM recommends 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 systems) is

increasing, and according to

the EPRI report, the demand

for DC distribution is

expected to expand up to

50% by 2020.

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 would 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 leading power factor ¹

• As the lagging power factor ² also increases the supply capacity, the leading phase power

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

power factor due to the Ferranti phenomena.

• At night time, the transformer has been made overexcitation 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 leading power factor be more strictly controlled than the lagging 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

11Introduction of JAGUAR IoT solution - Power quality measurement and energy saving consulting

• Procedure • Success stories

At first, the demand power has been made for new building with 2 floors underground

and 8 floors upper ground. 85kW has been contracted, by calculating as 65% demand

of total load capacity. As the result, it becomes to be necessary to contract Safe

manager as mandatory duty of Electric utility law.

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.
