MIKO-21 is designed for high precision measurements of DC electrical resistance in the range from 0.1 µΩ to 2 Ω with an accuracy of ±0.05% and can test: contacts of high-voltage circuit breakers of all types and voltage classes; contactors, relays, busbars, various bolted connections, welded joints, brazed joints; elements of equipment for open and closed switchgears in extreme electric and magnetic field conditions; in research laboratories and industrial workshops. MIKO-21 is ahead of similar devices represented on the market due to a number of functional and technical features. For example, special measuring technologies ensure MIKO-21 compliance with the most stringent accuracy requirements. MIKO-21 is ideally applicable for high precision resistance tests in the µΩ range.
- Single is started once the cable clamps are contacted to the tested object and followed by pressing the START button.
- Auto single circuit is initiated by pressing the START button. The instrument will start measurement when the electric contact between the tested circuit and the test cable contacts is set. The test can be repeated by pressing the START button again.
- Periodic is used in pre-specified time intervals when both hands are occupied with cable probes pressing against the test points. The user can choose time interval between the tests. The instrument will work continuously until the user stops the mode.
- Auto periodic circuit is initiated by pressing the START button and used for continuous measurements. The user connects the current cable, and as soon as the potential contacts are connected, the measurement will start automatically. To repeat a test, simply break contact with potential probes and reconnect.
Variable instrument complete set
For convenient connection to the object, there are special test cables of different lengths and different types of clamps: Test cables with Kelvin clamps for high voltage circuit breakers up to 110 kV 2 m long (standard complete set); Test cables with Kelvin double hand spikes 1.5 m long for measurement in pipelines and interrupting chambers (recommended when the device is placed near the circuit breaker); Test cables with Kelvin C-clamps for circuit breakers from 10 kV to 220 kV 4.5 m and 6 m long (recommended when the device is placed near the circuit breaker); Test cables that consist of a cable with Kelvin clamp and Kelvin C-clamp for circuit breakers from 220 kV to 750 kV 3m / 6m or 9m long (recommended when the device is places in a cradle of a lift); Test cable for precise measurements and measurements on sections of the electric circuit, to the end points of which the test current is applied.
