Product Description

KDCT-102 Secondary Voltage Drop And Load Tester

The excessive comprehensive error of electric energy measurement is a key problem in electric energy measurement. The measurement error caused by the secondary circuit voltage drop of voltage transformer is often the biggest factor affecting the comprehensive error of electric energy measurement.

The so-called error caused by the secondary voltage drop of the voltage transformer refers to the percentage of the amplitude difference of the voltage between the secondary terminal of the voltage transformer and the voltage terminal of the meter relative to the actual exit voltage of the secondary side of the PT, and the phase difference between the two voltages. KDCT-102 secondary voltage drop and load tester is a kind of automatic intelligent instrument for measuring secondary voltage drop/load of voltage transformer. It can realize three-phase three-wire, three-phase four-wire, single-phase automatic measurement.

 

 

KDCT-102 Secondary Voltage Drop And Load Tester

Product Characteristics
1, can achieve three-phase three-wire, three-phase four-wire, single-phase automatic measurement;

2, the use of engineering plastic chassis, durable, effective protection of testers and system safety;

3, the instrument has the automatic range switching function to ensure the test accuracy;

4, the use of electronic circuit combined with DSP technology is to make the test stability is good, strong anti-interference ability;

5, after the measurement is completed, the parameters related to the load are automatically calculated, which is convenient for customer analysis and test.

6, the use of large screen Chinese LCD display, all operations are prompted by the Chinese menu; The data has power down storage and browsing functions, and can be transmitted online with the computer.

7, the use of large capacity 7.2V11Ah lithium battery power supply, does not have any impact on the test circuit, to avoid system protection. It can also be used when there is no power supply on site.

8, secondary load test, the use of clamp ammeter sampling current, do not need to disconnect the secondary loop. Online measurement can be achieved without power outage. Automatic switching range: The measurement process can be switched to different positions according to the different values of the test object, so that the measurement accuracy and display digits are guaranteed.

9, the working time can be up to 24 hours (maximum).

10, with a lightweight charger, easy to measure, in the case of insufficient battery power can be connected to the external charger measurement.

11, small volume, light weight.

12, extremely wide secondary working current/voltage range. At 50mA working current, the resistance and reactance of 1mΩ can be distinguished, and the actual online load of S-class current transformer with secondary rated current of 5A can be tested. At an operating voltage of 5V, conductance and susceptance of 0.001mS can be distinguished.
13, Store 480 sets of measurement data, can be maintained for ten years after power failure.
14, Chinese interface large screen display, with RS-232 communication interface.

Environmental condition	Temperature: -5ºC ~ 40ºC Relative humidity: < 95% (25ºC) Altitude: < 2500m External interference: no extra-strong vibration, no extra-strong electromagnetic field
the main technical indicators of the instrument during the secondary pressure drop test	1) Measuring range: ratio difference: 0.001% ~ 19.99% Angle difference: 0.01 '~ 599' 2) Resolution: ratio: 0.001% Angle difference: 0.01 ' 3) Basic error of the instrument X=(2% X X+2% x Y2 words); Y=(2% X X+2% x Y2 words). Two words - quantization error of the instrument 4) Voltmeter head accuracy: 0.5% 5) Scope of work Voltage: (50 ~ 120)V 6) Instrument indicating action value (prompt error) Error: ratio difference greater than 20% or Angle difference greater than 600 '. Voltage: Voltage < 2.0V.
PT secondary load test instrument main technical indicators	1)PT secondary load test Admittance measurement range: 0.1ms-50.0ms Admittance measurement accuracy: Secondary voltage (50V-120V) X=(2% X X+2% x Y2 words) Y=(2% X X+2% x Y2 words) Two words - quantization error of the instrument Note: When the measurement value is below 0.2mS, the test voltage should be kept above 50V, and the core conductor of the clamp meter should be kept centered. At this time, the quantization error of the instrument is 5 words 2) Voltmeter head: 0.5%
CT secondary load test instrument main technical indicators	Impedance measurement range: 0.1Ω - 50.0Ω Impedance measurement accuracy: X=(2% X X+2% x Y2 words) Y=(2% X X+2% x Y2 words) Quantization error of a 2-word instrument Ammeter head: 1%
