Transformer Turn Ratio
The transformer turns ratio is the number of turns of the primary winding divided by the number of turns of the secondary coil. The transformer turns ratio provides the expected operation of the transformer and the corresponding voltage required on the secondary winding. Single-Phase TTR Single-Phase TURA series devices can test transformer turn ratio and calculate error as a percentage. By testing the turn ratio operator can understand how much voltage they will get from the secondary side precisely. TURA single-phase series turn ratio meters can test three-phase transformers also. Three-Phase TTR TURA-03 series turn ratio meters can test turns ratio by making only a one-time connection to transformers and automatically test all phases. TURA-03 series turn ratio testers can [...]
Winding Resistance
WinRes-20 winding resistance meter can make precise and fast measurements in even small and big power transformers. WinRes-20 winding resistance meter can measure from 0.01 microohm to 100,000 Ohm resistance value. WinRes-20 winding resistance meter has a 7-inch display and can be expandable with a three-phase adapter.
Circuit Breaker Timer
Why do we need to test circuit breakers? It is very important to test circuit breakers regularly. Contact Timing Tests and Motion tests are performed to determine the optimal performance of the breakers. The testing can determine improper breaker operations in case of system fault and to improve system reliability. Contact Timing Tests Contact timing tests are performed to compare the breakers’ main & resistor contact performance against the manufactures specifications. The breakers OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN & OPEN-CLOSE-OPEN operations are timed in milliseconds (ms) and cycles and then compared with the manufacturers’ specification to determine the performance of the circuit breaker. CIBRE-L6B BLUE features with a 4.3-inch large colour touch display, which is visible under both bright sunlight as [...]
