Megger 210600 Offers

Key Features

• Guard terminal to eliminate surface leakage current from the measurement
• High-resistance readings up to 20,000 MΩ (analog model)
• Digital autoranging with readings up to 1999 MΩ (digital model)
• Multiple test voltages

The 210600 Megger® Extended Range Insulation Resistance Tester is the ideal instrument when high ranges are needed for measuring insulation resistance. It provides excellent test voltage regulation and an external guard terminal to eliminate surface leakage current from the measurement. The instrument is all electronic; it generates a regulated dc high voltage and uses low-zero-drift, high-accuracy circuits, with high current sensitivity. Designed for portability, it is enclosed in a molded, impact-resistance, flame-retardant case.

The 210600 is protected for connection to power distribution systems up to 300 V Line-Ground and 500 V Line-Line for Installation Category III. This relates to transient overvoltage likely to be found in fixed installation wiring.

This digital, autoranging model provides insulation resistance readings up to 1999 MΩ. It has a 0- to 600-volt ac measuring range. Test voltages of 100, 250, 500 and 1000 volts dc are selected by a rotary switch, and insulation resistance to 1999 MΩ autoranging can be made on the 500 and 1000 V ranges. It incorporates a 3-1/2 digit LCD calibrated directly in megohms, ohms and ac/dc volts.

Applications

Major Megger testers measure the insulation resistance of wires, power cables, motors, generators, transformers, switchboards and electrical controls. Both models offer multiple test voltages for performing spot and step-voltage tests.Typical applications include:

• Acceptance testing at time of installation to check conformance to specifications.
• Routine preventive maintenance testing after installation.
• Quality assurance testing by the manufacturer.
• Diagnostic testing to isolate faulty components for repair.

Major Megger insulation testers can be used for detecting high- or low-resistance grounds, short circuits in apparatus, cables, wiring, etc. whether caused by moisture, oil, dirt, corrosion, damage to insulation or natural deterioration. They can also be used to determine the presence of moisture, solvents and semiconducting foreign materials in wires, cables and other conductors, and in built-up insulation systems such as those found in motor windings.

Typically, these testers are used to take a series of measurements over a period of time which will show the gradual decline that takes place in the insulation during its operational life. Such monitoring enables the user or to anticipate future performance and to plan ahead for repairs. They are also used to show improvements in the insulation of motor, transformer and generator windings that result from drying-out procedures used after exposure to excessive humidity or water.
