It is a technique that helps to test and remove errors in our program or hardware design. CT test sets are small, multi-function units designed to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. Check out our book shop for essential reading and reference on electronics related topics:
A constant DC voltage, usually 10 kV, is applied to the open contacts, and the current flow through the VI is measured. If the conductor is of a uniform impedance and is properly terminated, then there will be no reflections and the remaining incident signal will be absorbed at the far-end by the termination. Measurements are obtained by passing a known DC current through the winding under test and measuring the voltage drop across each terminal (Ohm's Law). This is equivalent to the way that an electronic time-domain meter measures reflections caused by changes in the impedance of the cable under test. Find out about the different types of test instrument available. It comes with rotary switches for setting up the voltage and current. The high current or primary-injection test set consists of large transformers that step down line voltage (ex. It will then calculate the impedance. All Rights Reserved.
But before going to know about the list of electrical test equipment. One point is for applying the current and the other for measuring the potential.
Current output is controlled by a tap changer and variable resistor. Two terminals carry the current from the meter (C1, C2), while the other two allow the meter to measure the voltage across the resistor (P1, P2). Leave us a comment below or tweet us @BlileyTech! The large reduction in voltage allows for a large increase in available current output (15kA+), especially for a short duration.

The main shortcoming of the secondary current injection test method is that only the solid-state trip unit logic and components are tested. In order to discover whether a circuit is working, and then where the problem is located, it is necessary to use various forms of test equipment. Moreover, there may be issues with the assembly, wiring the circuit or components. Low voltage, high current outputs are used for primary-injection testing of low voltage circuit breakers. Traditional field testing of vacuum interrupters utilizes the hi-potential test in order to evaluate the dielectric strength of the bottle, this test produces a go/no-go result that does not determine when, or if, the gas pressure inside the bottle has dropped to a critical level.
