3. Applications

☆ Calibration of DC Electrical Measuring Instruments

TUNKIA TD1545 DC Energy Meters Verification Device

• Calibration of DC voltmeter and ammeter: the device has a built-in DC voltage standard source with an output range of 10 mV ～ 1550 V and a DC current standard source with an output range of 1 mA ～ 600 A. The voltage and current accuracy of the 0.02 level device reaches 0.01 level, which is applicable to the calibration of DC voltmeter or ammeter of 0.05 level and below.

• Calibration of DC power meter: a virtual power standard source composed of independent DC voltage and current output. The accuracy of a 0.02 level device reaches 0.02 level, which is applicable to the calibration of DC power meters of 0.1 level and below.

• Advantages: This integrated multifunctional DC standard source, with its excellent accuracy and stability, can be regarded as a portable mini - DC electrical laboratory. It covers the calibration of commonly used DC instruments, reducing the initial investment for users while being practical and cost effective.

☆ Calibration of DC Energy Meter

TUNKIA TD1545 DC Energy Meters Verification Device

• Application scenario 1: The maximum DC voltage output is 1550 V, meeting the requirements of 1.15 Un voltage test of 1 kV electrical energy meter; The maximum DC current output is 600 A, meeting the requirements of 1.2 In current test of 100 A electrical energy meter. With the power pulse measurement function, the test of direct connected DC watt hour meters for measuring DC electrical energy can be completed.

• Application scenario 2: The instrument has 10 μV~11 V four wire small signal voltage source, with 1550 V DC voltage source and electric energy pulse measurement function, can carry out the verification of indirect access DC electric energy meters.

• Application scenario 3: The maximum output of DC current is up to 600 A, which can be used as the primary current input of the DC shunt. With 1550 V DC voltage source and power pulse measurement function, the overall verification of the DC shunt + indirect connected meters for measuring DC electric energy can be achieved.

• Calibration items: basic error, start-up test, creeping test, instrument constant test, and clock daily timing error.

• Advantages: Batch calibration of energy meters is usually performed using multi - meter position bench - top devices. However, for the development and testing of meters, additional test equipment is often required. In such cases, bench - top devices are usually inconvenient to use. The TD1545, however, stands out for its functionality, portability, and cost - effectiveness. Its technical specifications can also cover the testing of mainstream - specification DC energy meters.
