What?

Used when precise measurements are necessary, for example, for contractual applications that may require resolving disputes, verifying compliance with standards, etc.

This is a tool for understanding the power trend and consumptions, constant monitoring, analyzer power quality, trouble-shooting applications and other applications where low uncertainty is not required. 

Power loggers are instruments for you to understand the power trend and constantly monitor. 

The AC Clamp Power Meter is a tool for you to check the power at sites from manufacturing plants to households. 

When?

When you need to examine, diagnose and countermeasure the power supply condition that causes troubles to the equipment. 

When two different lines a measurement need to be measured simultaneously. 

When you need to conduct a power survey to understand the load size in a system or to understand the power quality in a system. Also useful for preventative maintenance. 

When you need to understand the power consumption of a facility or system, to support power saving activities to achieve your sustainable development goals. (SDGs) 

When you need to detect electricity theft, and check the power condition at the power transmission and distribution side. 

Who?

Data centers engineers, power utility engineers, power measurement consultants, power quality specialists, substation facilities manufacturer, and engineers who measure commercial line inverter efficiency. 

Facility managers, plant managers, industrial engineers and technicians, utility companies engineers and power consultants. 

Facility managers and utility companies. 

Utility companies electricians and on-site technicians. 

Why?

The two line measurement feature is a dedicated function for measuring two different lines accurately and safely. High sampling rates for transient measurement and high-order harmonics measurement capability help to identify the cause of the power quality issues. The dedicated software, PQ One with statistical data analysis will help you to understand and analyze your power condition. 

The Quick Set function will help you with the power survey settings and makes your power quality survey much easier. The dedicated software, PQ One with statistical data analysis will help you understand the analyze your power condition. 

Compact size for easier installation in distribution boards. Being able to use the power supply from the line will also help you with long term period power surveying. Non metallic contact for safety power measurements.

The bluetooth connected application, GENNECT Cross, will help you identify when there is electricity theft. Easy to use for checking the power condition from single phase to 3 phase connection systems.

Harmonics Measurement

Application Use

Basic Harmonics Measurement

THD Measurement (V & I)

This value can be monitored to assess waveform distortion for each item, providing a yardstick that indicates the extend to which the total harmonic components are distorting the fundamental waveform

Harmonics 1 to 30 for V & I

When the level of the harmonic component is high, it may cause serious accidents such as overheating or noise in motors or transformers, and burn out reactors in phase compensation capacitors

(1-40. PW3360-21)

(1-13)

Advanced Harmonics Measurement

Harmonics 0 to 50 for V & I

When the level of the harmonic component is high, it may cause serious accidents such as overheating or noise in motors or transformers, and burn out reactors in phase compensation capacitors.

-

Inter-harmonics

Inter-harmonics are caused when the voltage or current waveform is distorted due to static frequency conversion equipment, cycloconverters, Scheribus drive, induction motors, welders, or arc furnaces. The term refers to frequency components that are not a whole multiple of the fundamental wave.

-

-

Frequency fluctuation

Frequency fluctuation occurs due to line separation caused by circuit issues, shutdown of a high-capacity generators, or changes in the supply/demand balance of active power. 

-

-

-

Transient voltage (impluse)

Transient voltage occurs due to the phenomena such as lightning, breaker damage, or closure on the circuit breaker or relay. It often occurs when there is a radical change in voltage or when the peak voltage is high.

-

-

-

Voltage dip (SAG)

Most dips are caused by natural phenomena such as lightning. When an equipment fault is detected and taken offline due to the occurance of a power system ground fault or short-circuit, a large inrush current caused by a motor startup or another load can occur, causing a temporary voltage dip.

-

-

-

Voltage swell (SURGE)

Swells occur when the voltage rises momentarily. Some examples of this are when a power line turns on or off due to lightning or a heavy load, when a high-capacity capacitor bank is switched, when a one-line ground occurs, and when a high capacity load is cut off. This phenomenon also includes voltage surges due to grid-tied dispersed power supplies (e.g Solar Power).

-

-

-

Flicker

Flicker consists of voltage fluctuations resulting from causes such as blast furnaces, arc welding, and thyristor control loads. Manifestations include light bulb flickering

-

-

-

Interruption (momentary power outage)

Interruptions consist of momentary, short term, or extended power supply outages as a result of factors such as circuit breakers being tripped due primarily to power company issues (interruption of power due to lightning strikes, etc.) or power supply short-circuits. 

-

-

-

Unbalance

Unbalance is caused by increases or decreases in the load connected to each phase of a power line, or by distortions in voltage and current waveforms, voltage dips, or negative phase voltage caused by the operation of unbalanced equipment or devices. 

-

-

-

Inrush Current

Inrush current is a large current that flows momentarily, for example when electric equipment is turned on
