Description
Overview
GAOTek portable high voltage circuit breaker tester performs three main tasks When closed, they must conduct the current as effectively as possible. When open, they must insulate the contacts from one another as effectively as possible. In the event of a malfunction, they must disconnect the fault current as quickly and reliably as possible, thereby protecting all subsequent equipment. In the US market and regions of frequent earthquakes, the most popular high-voltage circuit breakers are “dead tank” units, whereas in central Europe “live tank” breakers are standard. In other parts of the world, both circuit breaker types can be found. In the worst case, a circuit breaker might stand still for several years, but then, in the event of a malfunction, it must disconnect fault currents of many kiloamps reliably within just a few milliseconds. Typical faults that occur on circuit breakers are short circuits in the coils, incorrect behaviour, for example due to worn contacts, as well as damage or wear to the mechanical connections or the insulation material. Therefore, circuit breakers need to be regularly and carefully tested. Circuit breaker testing typically focuses on performing motion and time measurements on the units. However, our testing solutions have revolutionized circuit breaker testing. The testing solutions we offer include systems that can supply power during the testing process and can measure the micro-ohm resistance across the closed contacts. Performing the tests without use of the station battery greatly increases safety throughout the testing process. high voltage Circuit Breaker Tester can test the vacuum circuit breaker, sf 6, oil circuit breaker, GIS etc. the test parameters include, close or open time, delta time, bounce time, bounce cycles, multi-operation, stroke, gap, over-travel, overshoot, rebound and the speed, with the ability of test results and graph display. The T-209 is the instrument platform for circuit breaker maintenance based on decades of experience and thousands of delivered breaker analyzers. The modular construction makes it possible to configure this product for measurements on all known types of circuit breakers in operation on the world market. The robust design contains powerful technology that streamlines circuit breaker testing. Sophisticated measurement modules enable great time savings as many parameters can be measured simultaneously, eliminating the need for new setup each time. The patented Dual Groundâ„¢ testing using the DCM module makes the testing safe and time saving by keeping the circuit breaker grounded on both sides throughout the test. The DCM module uses a measuring technology called Dynamic Capacitive Measurement. Timing M or R is using the patented Active Interference Suppression to obtain correct timing and accurate PIR (Pre-Insertion Resistor) values in high voltage substations. An adaptive, easy-to-use software suite supports activities from timing, simply turning a knob without the need for presetting, to advanced help functions for hooking up to the test object. A keyboard and 5.7 in (14.48 cm) screen the front end of the high-level user interface. The Select-Connect-Inspect workflow guides you to fast results in three steps. Testing is made easier to learn and perform. The system also offers full connection capability to the local network, printers etc.
