How to purchase an excellent electrical measurement device?
Apr-09-2013
Good morning! Today I’d like to talk about some tips of how to purchase electrical measurement devices, and I hope this is useful for you. Electrical measurement device is a concept of general word. As we know, Multi-meter, installation type instruments belong to electrical measurement devices. Here, we mainly discuss how to choose installation type digital meters.
Well, digital meters, according to the function, can divide as follows: Voltage meter, Current meter, Active (Reactive) power meter, Frequency meter, Power Factor meter etc, including the all-in-one function type called intelligent multi-meter. This part mainly discusses some common sense.
Instrument accuracy
Electrical measurement devices include 7 classics: 0.1; 0.2; 0.5; 1.0; 1.5; 2.5; 5.0
The level refers to error percentage of instrument when it come full range.
For example, the accuracy of 193I-9X4 three-phase current meter manufactured by Blue Jay is 0.5 with input current of 5A. That is to say, when this current meter measures full range current of 5A, the maximum of error percentage won’t be 0.5
Another way to discuss device accuracy is called uncertainty level. We’ll talk it next time.
Digital meter and analog meter
Digital meter is known for its precise reading and high accuracy.
The strengths of the analog meter, according to the motion of pointer, we can know the change trend and scope.
Our company, specializing in "power control, power protection automation" equipments, is a fist-class manufacturer. We offer intelligent digital meters for energy saving and eco-friendly.
Power supply
Generally talking, power supply can divide three types, transformer power supply, switch power supply, and the battery.
Transformer power supply:

Strong anti-interference ability and anti-harmonic, but solo input voltage classic that DC not available
Switch power supply:

Wide input voltage range 70~250v Poor anti-interference ability, especially in heavy harmonic places like steel plant
Input measurement signals
The accuracy of DC is far higher than AC.
The true effective and average value
The multi-meter shows average digital of power parameters in a very short period of time.
Installation type meters precisely display power parameters digital in real time, having the characteristics of strong anti-interference ability anti-harmonic and frequency variation.
Optional functions
There are some optional functions, besides the general measurements.
Communication function: Supporting RS485 and MODU BUS protocol
Analog output function: 4~20mA
Control function: When the voltage is overload to setting value, the meter can alarm by relay output.
C/T ratio setting
The full range of current meter can be set based on installation transformer. And the setting value is any one of 5A~8000A according to our country standard.
Respond speed
Digital meters generally adopt specialized chip giving consideration to multi-functions and respond time is slow down. Only 3 ~ 5 digitals are available in one second.
Our company, Blue Jay Electronic digital meters can show 50 digitals in one second with high precision and strong stability. The respond seed is quite fast for customer satisfaction.
Other frequency meters
What we talked above is all about meters of frequency 50 Hz.

But there are some other frequency meters for special field application. Like digital meters of frequency 40 Hz are for aeronautical application, and meters of frequency 20 Hz for super audio power and transformer output current.
Blue Jay Electronic can satisfy customers’ need by manufacturing different frequency of digital meters.
Digital monitor software
When using digital meters with RS485 communication, customer generally has to write digital-monitor programmed manual. That is troublesome.

Our company is for free writing this manual for customers to improve production efficiency. For customers, we do best.
At last, thank you for reading.

Comments of the distributed power on-gird service from China
Mar-03-2013
China State Grid Corporation recently publish <Comments of the distributed power on-gird service>, following the support of distributed photovoltaic grid, the State Grid Corporation will support be extended to wind power, natural gas and other types of distributed power. Various provinces and cities have introduced a specific mode of operation guide.
Definition of distributed power is located near the user, the power can place the use of grid voltage level of 10 kV and below, single and outlets does not exceed the total installed capacity of 6 MW power generation project. Including the type of solar energy, natural gas, biomass, wind energy, geothermal energy, ocean energy, resources comprehensive utilization of power generation.
In terms of price settlement, distributed power grid to the implementation of the upload, download charge separate settlement, tariff implementation of relevant national policies. Distributed photovoltaic power generation, wind power project, the company is free to provide the gateway metering device and the measurement electricity generating capacity.
China Government plans in 2015 to build 1000 natural gas distributed energy projects, 10 natural gas distributed energy demonstration area; distributed solar power generation will reach 10 million kilowatts, the new energy model city built 100-based distributed renewable energy applications.
Expected spurt in the future for the distributed power of individual users bidirectional energy measurement instrument, Blue Jay Electronic will seize this opportunity, in existing small metering equipment technology, and integrate the Internet of Things technology, to publish a new measurement products. The main target customers are small businesses and house users, can be able to do measurement, data analysis, monitoring of energy storage devices integrated monitoring functions products.
