Oil dielectric loss tester based on IEC and the relevant provisions
of the state, to play their own technological superiority, and
carefully developed high-precision, digital instrumentation. The
apparatus uses high-frequency induction heating, even heating, fast
temperature rise speed, short time. The microprocessor control and
calculation, realize automation, capacitance and dielectric loss of
high measuring precision, stability, good repeatability of data.
Output voltage of 0 ~ 2000V is continuous and adjustable, suitable
for different sample the voltage level required. Widely used in
transformer oil, capacitor oil and cable oil dielectric loss
1, the use of the apparatus before must carefully read this manual.
2, the operator should have the general electrical equipment or
instruments to use common sense.
3, the instrument should avoid vibration.
4, the apparatus must be grounded reliably, to prevent the risk of
5, after the test, press the reset button, turn off the power
switch, and is charged each test cable and replace the oil sample.
6, equipment maintenance, must not in the case of electricity, or
7, prohibit the empty cup if heating, heating temperature, must be
added to the measurement of dielectric loss of oil and oil
III. performance characteristics
1, using electromagnetic induction heating technique, even heating,
fast temperature rise speed, short time.
2, the output voltage 500V ~ 2000V is continuous and adjustable,
suitable for different sample the voltage level required.
3, the temperature control is accurate, is not affected by
environment temperature influence.
4, high measurement accuracy, stable, reproducible data.
5, a boot detection circuit, no grounding or earthing is not good
to give a hint.
6, a short-circuit protection circuit, short circuit and high
voltage output circuit.
