Thank you to all clients concern and support ETCR. To celebrate the 73rd anniversary Chinese Nation Day, ETCR will have a holiday from 1st, OCT to 7th,OCT 2022 (7 days in total). During this time. we will be out of office. and we will start to work on 8th,OCT 2022. Here we apologize for the inconvenience in advance! Meanwhile, in the new working stage, we will carry out promotional activities for many models instruments (including Earth Resistance Tester Series, Insulation Resistance Tester Series, etc.clamp current meter series, high/low voltage current meter series, high voltage detector series), and these series instruments will provide very favorable offer. If you are interested, don't hesitate, contact us immediately for more Promotions! During the holiday, our sales would check mails and messages as usual, and will reply your in time. Thank you again for your continued attention and support to ETCR! ETCR team wishes all of our clients and friends all over the world can be health and share our happiness!

The single-phase grounding fault of 10KV overhead line is a kind of fault that often occurs in high-voltage overhead lines, which will seriously affect the normal power consumption of users. In severe cases, it may damage the substation equipment and cause major safety accidents. Single-phase ground fault :single-phase metallic grounding, arcing grounding, transition resistance grounding, insulator breakdown, and lightning arrester breakdown,etc. ETCR1400 Overhead Line Ground Fault Detector apply for single-phase ground fault detection of overhead high-voltage lines, and accurately locates the ground fault point. Accurately search hidden ground faults of overhead line such as single-phase metallic grounding, arcing grounding, transition resistance grounding, insulator breakdown, and lightning arrester breakdown,etc. Product Features 1. Innovative integrated the signal transmission and acquisition in a detection clamp. The clamp-shaped structure is convenient for detecting. The line fault test can be completed in once clamp detecting, which is no need to output and acquisition singal operations in two sites, and no need to disconnect the PT(phase voltage transformer). The detection is convenient and fast, reduce the number of operators and improving work efficiency. 2. The detection clamp is equipped with th non-contact electroscope. If the tested line is electrified, the detector will issue a light alarm, and the host will broadcast a voice prompt to ensure the safety of operators and equipment. 3. Especially suitable for faulty lines with cable branches. Strong short-circuit detection ability, which can detect the direct short-circuit fault of  0Ω grounding resistance. 4. The output voltage is up to 8000V, and there are two options of 8000V and 3000V to meet the different reqeust of users. 5. Equip with the large-capacity rechargeable battery, can complete the detection of the entire overhead line after being fully charged. 6. The detection speed is fast, and the test results can be obtained in a few seconds after hooking up the detector. 7. 7-inch color screen can display the fault direction is obviou and clear. 8. With Voice broadcast function, prompt fault direction. 9. With Bluetooth communication function, the communication distance up to 40m. After download and install the APP, can make the  test and view the test results on the mobile phone, which can use as a handheld receiver. Innovative integrated the signal transmission and acquisition in a detection clamp The line fault test can be completed in once clamp detecting, which is no need to output and acquisition singal operations in two sites, and no need to disconnect the PT(phase voltage transformer). The detection is convenient and fast, reduce the number of operators and improving work efficiency. Non-contact electrometry The test needs to be carried out when the high-voltage line is out of service, but there may still be in...

ETCR8600B contains 15 gear current values, but how does ETCR8600B set the current gear? Function rotary switch 1. V~ gear: This symbol is the AC voltage test gear, this gear can measure AC voltage below 600V; 2. ×1/2 gear : This gear indicates that the current displayed in the setting window is ×1/2, which is also half of the current displayed in the window; 3. ×1 gear : This gear represents the ×1 of the current displayed in the setting window, which is the same as the current displayed in the window; 4. ×2 gear : This gear represents the ×2 of the current displayed in the setting window, which is twice the current displayed in the window; 5. Auto : This gear indicates automatic mode. In automatic mode, the meter automatically outputs from low current to high current in sequence until an action occurs. Current Setting Set default value : 10mA / 20mA / 30mA / 100mA / 300mA / 500mA Corresponding Gear Value Current setting 10mA 20mA 30mA 100mA 300mA 500mA X1/2 gear mode 5mA 10mA 15mA 50mA 150mA 250mA X1 gear mode 10mA 20mA 30mA 100mA 300mA 500mA X2 gear mode 20mA 40mA 60mA 200mA 600mA 1000mA ETCR8600 Leakage Protector Tester is designed to test the line AC voltage, leakage initiating current, residual non-operating current and leakage initiating separation time of various leakage protectors online, the test current from 5~1000mA with 16 grade (5、10、15、20、30、40、50、60、100、150、200、250、300、500、600、1000mA), range of the leakage initiating separation time is 0~999ms.The required output current value can be set according to the table

ETCR9500BThree Channel Wireless High Voltage Transformation Ratio Tester break through the traditional structure, special designed and manufactured for online measurement of current transducer, transformer primary current and secondary current, transformation ratio, phase and polarity judgment below 35kV in operation. The instrument is composed of primary current clamp (high voltage detector), secondary current clamp, host machine, high voltage insulation rod, monitoring software, communication cable, etc. the test data of primary current clamp adopt wireless to transmit which transmission distance of 100 meters. The current clamp is made of high performance permalloy with magnetic shielding technology, which is almost free from the influence of the external magnetic field, ensuring the long time uninterrupted monitoring of high accuracy, high stability and high reliability. The host LCD display clear and obvious, with large storage space, can store 3000 groups of data. The high voltage detector connect with 5pcs insulation rods, used for high voltage line current measurement which the wire with insulation skin below 60kV or the bare wire below 35kV, high voltage current clamp have unique automatic plug and pull structure, by pressing or pulling out the insulation rod can be easy to clamp or withdraw the tested line, saving time and more effective. It is widely used in substations, power plants, industrial and mining enterprises, inspection stations, electrical maintenance departments for current detection and electrical field operations. The insulation rod is handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on.
