K7GE-MG

Condition Monitoring Device – insulation monitoring

K7GE-MG performs an automatic measurement of the insulation resistance as soon as the device is powered-off, avoiding the need for periodic manual measurement, and allowing to evaluate the deterioration trend of insulation resistance thanks to the increased measurement frequency.

K7GE - MG is suitable with AC/DC motors, Servo and Electric Heaters, and collects data on PLC and/or related software and generates an alarm whenever the warning/critical threshold is exceeded.
 
A single controller can handle up to 8 devices, and its unique technology allows to perform insulation with a safe fixed 50V DC and allows for an eventual additional periodical check with MegaOhmeter without the need for disconnecting the K7GE.
  • Automatic insulation measurement when the motor/servo is OFF
  • Low voltage measurement with no overload on the machine equipment
  • Easy to install and retrofit

Features

Highly reproducible measurements

Trend monitoring is not possible if measurement fluctuates due to measurer’s lack of insulation resistance measurement know-how. However, K7GE can contribute to trend monitoring because tasks that cause measurement fluctuation may be set up by parameters, allowing for highly reproducible measurement.

High frequency of measurements to accurately identify equipment abnormalities

K7GE-MG enables automatic measurement that can be repeated every time the device is switched off.This helps avoid sudden stoppages due to insulation degradation which conventional inspections conducted at long intervals may miss.

Automatic measurement depends on equipment condition

The automatic measurement eliminates any risk of equipment failure by stopping measurement if the equipment power is restored after its start.

Automatic measurement reduce electric shock accident for worker

K7GE helps reduce risk of work accidents such as electric shocks since measurement is automatic and does not require manual tasks.

Reduced risk of equipment failure due to measurement with fixed 50 VDC

Remote condition monitoring for automatic insulation resistance measurement

K7GE enables remote monitoring from the office via network connection using a touch panel, PLC, and communications converter. It also allows on-site measurement results confirmation and parameter setting changes via the Main Unit indicator.

Easy measurement data collection and trend monitoring by using a dedicated tool

K7GE data collection tool runs on Excel, allowing for direct analysis  and processing.

User-friendly features that support the trend monitoring

1. Scalable Probe Units

K7GE supports up to eight Probe Units for measurement targets on the same system. It provides for a space-efficient installation as the number of Probe Units can be scaled in accordance with the number of measurement targets.

*1. The Main Unit and Probe Units are sold separately; purchase in the required combination for use.

2. Easy to install and retrofit

Easy to retrofit since it can be used just by wiring to the power cable of the target equipment.

3. Maintenance timing notification by two-level alarm: warning and critical

The threshold for indicating the degree of degradation can be set in two levels. Anomaly scan also be confirmed through communications data. This feature enables identifying the optimal timing for maintenance without visiting the site frequently. Furthermore, a load (such as an anomaly detection indicator) can be directly connected to the units transistor alarm outputs.

*2. Factory default settings

4. Periodic inspection by Megohmmeter

K7GE does not have any impact on measurement results by the Megohmmeter since its internal drycontact isolates it from the equipment target of measurement, except during measuring. Whenneeded, it can easily support measurement by calibrated measuring equipment as well.
