Four Functional Tests in One Megohmmeter with the AEMC 1026

by Protec Tech Team May 17, 2016

Measuring the quality of insulation involves checking the insulator’s resistance through the use of a megohmmeter. Acceptable insulator resistance values are typically 1 to 10 megohms, depending on the standards referenced.

Reduce Shock Hazards and Downtime with the Megger 210415 Megohmeter

by Protec Tech Team November 16, 2015

Insulators are designed to resist the flow of current from the central conductor towards the sheath of the electrical component, and protect the components from developing shorts or electrocution of personnel.

Rent Megger Insulation Resistance Measurement Equipment from Protec Now

by Protec Tech Team October 02, 2015

Insulation plays an important role in electrical systems. Without insulators, the electricity flowing in the conductors is exposed, which can cause short circuits or electrocution to personnel, and therefore it is important to always check the condition of the insulation to ensure safety and reliability.

For Dielectric Absorption Test Equipment Rely On Protec

by Protec Tech Team August 07, 2015

The ratio of two time-resistance readings (such as a 60-second reading divided by a 30-second reading) is called a dielectric absorption ratio. It is useful in recording information about insulation. If the ratio is a 10-minute reading divided by a 1-minute reading, the value is called the polarization index.

For All Your Insulation Resistance Testing Needs Rely on Protec

by Protec Tech Team August 05, 2015

Insulation is subject to many elements that can cause it to perform at a less-than-acceptable level. Excessive heat or cold, moisture, vibration, dirt, oil, and corrosive vapors can all contribute to deterioration. For this reason, routine insulation testing is necessary.

Rent the Megger 210415 Megohmeter for Accurate Insulation Resistance Testing

by Protec Tech Team February 02, 2015

Insulation resistance testers can be used to determine the integrity of windings or cables in motors, transformers, switchgear, and electrical installations. The test method is determined by the type of equipment being tested and the reason for testing. For instance, when testing electrical cabling or switchgear (low-capacitance equipment) the time-dependent capacitive leakage and absorption leakage currents become insignificant and decrease to zero almost instantly. A steady conductive leakage current flow is reached almost instantly (a minute or less) providing perfect conditions for the spot-reading/short-time resistance test.

Megger 210415 Measures Insulation Resistances of Up to 100,000 Megohms

by Protec Tech Team November 10, 2014

A megohmmeter (sometimes referred to as a megger) is an electrical test instrument designed to test extremely high resistances by producing a DC (direct current) voltage. A megohmmeter produces a high voltage, low current DC charge which allows for testing resistances commonly encountered in electric motor winding or cable insulation tests.
