TANGENS-3М - DISSIPATION FACTOR OIL

DESIGNATION:

Automatic facility to measure dielectric losses in transformer oil - Tangens- 3М (DISSIPATION FACTOR), (further in the text– Tangens- 3М ) is designed to determine tangent angle of dielectric losses tgδ (further – tangent angle of losses) in transformer oil (dissipation factor)l according to GOST 6581-75 at 50 Hz.

The Tangens- 3М is designed to operate in rooms at working air temperatures range from +15о С to + 35 о С, relative humidity 80 % at + 20 о С and atmospheric pressure 84,0 – 106,7 KP (630 – 800 mm.hg).

TECHNICAL DATA:

Range of tangent angle of losses measurements.

The facility measures tangent angle of dielectric losses tgδ, dielectric permeability ε, electric capacity С and voltage U, applied to measuring cell (further – working voltage), temperature of circuit-breaker oil sample.

Range of tangent angle of losses measurements - 0,0001 ÷ 1,0 (0,01 ÷ 100 %);
Errors in measurement of tangent angle of losses - +- (0,01 tg +0,0002);
Operating voltage applied to measuring cell corresponding to field strength 1МV/m, V - 2000;
Working voltage measurement range, V - 0 ÷ 2700;
Acceptable relative major error limit in working voltage measurement, % - 1,0;
Capacity measurement range, Pf - 5 ÷ 50;
Acceptable relative major error limit in capacity measurement, % - +- (0,5 + tg);
Range of radiator operation, +- С - 10 ÷ 100;
Accuracy in temperature measurement, +-С - +-1;
Measurement time including calibration and heating to 90 degrees (with measurements at 10 degrees),min.- 30;
Measurement time including calibration and heating to 90 degrees (with measurements at 10 degrees) and cooling, min. - 80;
Measuring cell according to GOST 6581-75,three-electrode type;
Cell volume, см3 - 13÷14;
Voltage of single-phase AC feed source, V - 205 ÷ 235;
Power consumption, kW, not more - 0,3;

The facility can operate with six different cells, their parameters are saved in non-volatile memory and are browsable from menu.

The facility saves up to 2000 recent measurements in non-volatile memory. List of standard equipment includes a software disk which enables to copy a file with measurements results from the facility to PC. File can be stored either in MS Word format or Excel. PC is connected to the facility via serial interface (RS232C). PC should be IBM operational system.
