Megger's 210170

The 210170 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 210170 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 unit provides high-resistance readings up to 20,000 M?. It features an analog meter movement calibrated directly in megohms, ohms and ac volts. Test voltages of 100, 250, 500 and 1000 volts dc are selected by a rotary switch. Insulation resistance measurements up to 20 G? can be made on all voltage ranges.

The unit is also equipped with a 0- to 5000-ohm continuity range and a 0- to 600-volt ac or presence of dc voltage measuring range. Power is supplied by an ac generator, driven by a hand crank, through a gear train.


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.
