1.Safety Instruction 1) The tester must be connected to earth properly before use. 2) The HV output terminals should be clean before starting test. 3) The test voltage is very high, so the users must keep enough safe distance from the sample and 4) 5) 6) 7)

high voltage circuit. The tester should be power off when making wiring connections. It is forbid to touch the terminals and cables when testing. Any replacement should be made after tester is switched off The tester should not be connected to the live power line at all.

8) The operator or user should get a certification of high voltage electrical test from local professional institute. 9) Please do not use the tester in rain, high temperature, large amount of dust environment 10) The tester should be repaired by certificated engineer in case that there is fault. The above warnings should be read and understood before using the tester.

2.Applications Tan Delta and Capacitance Tester TDC3000 is applied to measure the dissipation factor (PF) of insulating materials in heavy interference site, such as power plants, power substations etc.. It also can be applied in laboratory for high accuracy capacitance and dissipation measurement. The tester is all-in-one design: including precision digital bridge, power unit, internal reference capacitor (Cn), booster transformer and other electronic circuits. The typical applications of Tan Delta and Capacitance Tester TDC3000 are as following: 1)measure the dissipation & capacitance of power transformer and distribution transformer 2)measure the dissipation & capacitance of current transformer and voltage transformer 3)measure the dissipation & capacitance of high voltage circuit breaker 4)measure the dissipation & capacitance of high voltage motor 5)measure the dissipation & capacitance of insulation bushing

3.Technical Index The detailed technical indexes of TDC3000 are as following: 1)Test Standard: IEC60247 2)Dielectric Dissipation Factor(tgδ) measuring range: no limit accuracy: ±(reading×1%+0.00040) resolution: 0.001%
