5.After testing, please turn off the power and then charge the device. III.Overview HZ-9003C multifunctional partial discharge tester is used for on-line detection and location of partial discharge of HV equipment, which is designed based on our many years experiences in the partial discharge measuring fields. - Page 5 HZ-9003C Multifunctional Partial Discharge Tester include: device host 、 special partial discharge detection software、TEV sensor (TEV) 、ultrasonic sensor (USS)、ultrasonic concentrator (ELTW) 、high frequency CT (HFCT) 、UHF sensor (UHF) 、earphone and connecting wire.
- Page 6 The Multifunctional Partial Discharge Tester main computer is divided with several function areas, according to the above number indications, 1. Wave display 2. F1- F5 Menu Buttons 3. Power indicator 4. MEAS: measurement menu 5. AUTORANGE: Auto 6. MENU OFF: Menu off 7.
- Page 7 3.2 Charge Main Tester The main tester should be charged when first use, the fully-charged time is 7 hours. The charging time will reduce if the tester is partially charged. The charging will be stopped if the battery is fully charged. The charging status is indicated by the charging light at the panel.
- Page 8 The Multifunctional Partial Discharge Tester host is at automatic mode and collecting wave without trigger. The Multifunctional Partial Discharge Tester host is continuously collecting wave data by scanning method and displaying the wave data. ● The Multifunctional Partial Discharge Tester host stops wave data collection. The Multifunctional Partial Discharge Tester host has completed the single sequence acquistion.

When select “ single trigger” mode, the Multifunctional Partial Discharge Tester host can display the waves only after first trigger. When trigger mode is selected as “ single trigger”, the channel display will show” single”. When trigger mode is selected as “ automatic” or “ normal”, the channel display will show “... - Page 13 Composite TEV sensor wiring 2. Tester setting Open the tester, press and select CH1 to choose current channel to Channel1. Press “menu” button and then press F1 Key to select the” discharge detect” to TEV. Press F2 key to setup “output voltage” and “unit”. When use composite TEV sensors for detection the output voltage must be required.
- Page 14 Non discharge signals With discharge signals When the discharge signal detected by the switchgear cabinet PD tester is too large, the display screen data will change into red, the sensor is saturated at this time. Sensor saturated Background noise Instantaneous grounding voltage may occur outside of the switchgear cabinet due to the electromagnetic signal sources.
- Page 15 the metal bodies, otherwise it will affect the self-test. In order to make measurement, the TEV sensor shall be vertically parallel to the metal body to be measured. Once the tester is at continuous measurement mode, the readings will be display immediately. But if the TEV sensor is removed from the metal body, then the readings will not be displayed at the screen.
