SONEL MIC-15K1 (15kV) Insulation Resistance Meter

The Sonel MIC-15K1 Insulation Resistance Meter is designed to measure the insulation resistance of power objects such as single- and multicore cables, transformers, motors and generators, capacitors, switches and other devices installed in power stations. It is especially recommended for measurements in areas with very high electromagnetic disturbances, e.g. electrical substations with 1200 kV AC and 500 kV DC. Thanks to the 15 kV measuring voltage (in accordance with ANSI / NETA ATS-2009 TABLES 100.1) the meter can be used for measuring objects with a nominal voltage above 34.5 kV.

Capabilities of the device
Highly efficient HV inverter, with a test voltage of 15 kV and current up to 10 mA, suitable for measuring the insulation resistance up to 40 TΩ. Achieving such a result makes these meters unrivaled devices. Three-wire resistance measurement, performed using a "GUARD" wire, eliminates surface leakage currents caused by contaminated insulation, thereby increasing the reliability of obtained results.

The meter indicates the Dielectric Absorption Ratio DAR, Polarization Index PI and the value of Dielectric Discharge DD. The device allows the user to assess the condition of the insulation, by applying the test voltage incrementally in steps (SV - Step Voltage) or smoothly (RampTest - RT).
SV method ensures that a dielectric in good condition will provide the same results, regardless of the applied voltage.
RT method allows determining the characteristics of the insulating material. The meter smoothly increases the measuring voltage without exposing the object to so-called electrical stress. It records the time and voltage value at which the electrical breakdown of the insulation took place.
