Application

The Sonel MIC-5001 is an insulation resistance meter with adjustable testing voltage – up to 5 kV. It is a great tool for assessing the condition of electrical insulation in residential buildings, industry, railways, and other facilities of general use. Due to its parameters – excellent performance, low power consumption from batteries, the option of charging them during measurements, the convenience of use, and a  high ingress protection level – it is perfect for maintenance teams, testing motors, cables, street lighting or at the construction and maintenance of photovoltaic systems. The meter may be recommended to installers working on telecommunications and electric power systems that require the inspection of the insulation sleeve/sheath resistance (U_N ≤ 30 kV) to the voltage of 5 kV applied for 5 minutes.

Features

The meter may be used to measure the insulation resistance using the adjustable test voltage up to 5000 V. When testing the cables, it automatically discharges their load at the moment of completing the measurement.

MIC-5001 allows the user to determine the insulation resistance by applying linearly increasing voltage with the slope of 1 kV/s, according to standard EEE Std 95TM-2002. This functionality is called RampTest.

In contrast to the maximum test voltage, this slow and uniform method of applying test voltage protects the insulation against sudden “electrical stress”. This process may reveal defects that cannot be observed in classic R_ISO resistance measurement. If the tested insulation is weakened or defective, RampTest will enable the user to determine its maximum withstand voltage. In addition, this functionality is particularly useful in testing rotating machines or surge arresters.

The meter has a built-in voltmeter of AC and DC voltages in the range of up to 750 V. Extensive memory allows the device to record and send to a computer nearly 12,000 measurement results. Download Sonel Reader software from the manufacturer’s website to analyze the measurement results and present them in graphic form, e.g. current or resistance values shown in a function of time.

Capabilities

An essential advantage of the device is its ability to have a sufficiently long operation after one recharging of batteries. Electricians performing tests on repetitive objects or at short intervals do not have to worry about batteries discharging before completing the task. In addition, during the measurement work, the user may recharge the device from an external power source, e.g. a power bank of 12 V/2 Ah.
