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.


Megger MIT525 Insulation Resistance Tester Offers Simplistic Operation

by Protec Tech Team September 01, 2015

The Megger MIT525 5-kV Insulation Resistance Tester offers advanced features and rapid charge capability, with a range consisting of 5 kV and resistance measurement up to 10 TΩ. A key feature of the Megger MIT525 5-kV Insulation Resistance Tester is the ability to take measurements when connected to line power/mains with a dead battery.


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.


Sensitive Insulation Resistance Measurements Call For the Megger 210415

by Protec Tech Team December 31, 2014

The Megger 210415 15kV Analog Megohmeter is a high-voltage, line operated instrument, that provides a continuously variable test voltage for highly sensitive insulation resistance measurements of all types of electrical equipment and power cable.


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.


The Megger 210415 - a High Voltage Megohmmeter That’s Built Tough

by Protec Tech Team October 16, 2014

Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form on an LED screen.

Megohmmeters are instruments used to measure the resistance of insulators like electrical standoffs, surge arresters and cable insulation.


Megger MIT525 and MIT1025 Insulation Resistance Testers Provide Valuable Diagnostics

by Protec Tech Team August 26, 2014

Since a majority of electrical maintenance and testing involves evaluating insulation integrity, insulation resistance testing is very important. Electrical insulation starts to age as soon as it's made, and aging deteriorates its performance. Harsh installation environments, especially temperature extremes and/or chemical contamination, cause further deterioration, and as a result, personnel safety and power reliability can suffer. Therefore, it's important to identify this deterioration as quickly as possible so that the necessary corrective measures can be taken.
