HISAC Ultima – new generation Circuit Breaker Dynamic Test Set from SCOPE …. The ultimate solution for testing Circuit Breakers of all types. HISAC Ultima is the most complete analyser for checking the dynamic performance of CBs in live EHV switchyards upto 765 kV.HISAC Ultima can carry out Dynamic Contact Resistance Measurement on SIX breaks of THREE poles in one operation thereby significantly reducing stress on CB & testing downtime.HISAC Ultima with DCRM+ ensures end users safety by providing Dual Earth Test, in which Circuit Breaker will be grounded from both sides while conducting the test.It offers flexibility to create pre-programmed Test Plans including all test settings for all types of circuit breakers available in a switchyard that can simply be recalled at the time of actual testing. This saves you from doing all settings in switchyards.The Analysis software offers a range of utilities which enables effective Condition Monitoring of CB by comparing present test data with previous signatures and predicting future performance.

The Sonel MIC-5010 insulation resistance meter is a reliable tool for measuring insulation resistance up to 15 TΩ. The maximum measurement current is 1.2 mA or 3 mA, which guarantees the charging of an object with a large capacity in a short time. Each measurement, whether the programmed time expires or is manually interrupted, ends with the meter discharging the object. The device has unique algorithms that allow it to recognise the nature of the voltage present on the object, thanks to which the instrument can determine whether the voltage is the mains voltage – in which case the measurement will not be carried out – or whether it is the voltage generated by an electromagnetic field – in which case the measurement will be carried out. This makes it possible to carry out measurements in the presence of very strong electromagnetic fields where this was previously not feasible.The instrument is equipped with accessories which guarantee safety during measurements with all available voltages – both test leads, probes and crocodile clips meet extremely rigorous standards (guaranteed voltage strength up to 11 kV for test leads and 5.5 kV for crocodile clips and test probes). The accessories are supplied as standard with a handy carrying case. The high resistance of the device to interference means that cables as long as 20 m can be used for measurements.
