Analog Insulation Tester

What are Analog Insulation Testers?

There’s a resistance flowing between two points separated by electrical Insulation which is measured using an Insulation tester. All industries deal in electrical appliances, wires and cables. Due to usage for long periods of time and wear & tear, there is a risk of short circuits, faults, electric fire and other mishaps. To prevent these, Insulation Testers are used, which can identify current leakage or faulty insulation. Analog Display of these Insulation testers makes it convenient to use and easy to understand.

Safety Tips Before Using an Analog Insulation Tester

1. Always try to work on de-energized circuits. One should use proper lock-out/tag-out procedures to ensure safety.

2. Basic safety measures such as the use of protective gear, insulation mat, safety glasses, and insulation gloves is advisable. 

3. On de-energized circuits, look for any leakage current through fuses, switches, and breakers. Current leakage might result in inaccurate and unreliable readings.

4. Both before and after the test, discharge the conductor capacitance. Automatic discharge functions may be available on some instruments. 

Points to Remember before Purchasing Analog Insulation Testers

1. Voltage Range: It’s very important to know what voltage range is required. Multiple voltages are required if testing is to be done on a wide range of equipment. Insulation Testers are typically available in 1 kV and 5-kV variants. In general, 1-kV units can handle equipment that runs on 120, 240, or 480 Vac conventional distribution voltages. Utility and heavy industrial applications, on the other hand, require a 5-kV unit. It is not necessary to test equipment working at such high voltages as 13.2 kV at matching voltage. A 5-kV tester can nevertheless provide enough information to service and maintain high-voltage equipment.

2. Measurement Range: Before selecting the Insulation Tester, one should always be familiar with the actual reading that is expected from the installations, even if they are new. A tester with a limited range is short-changing the operator when it comes to capital equipment maintenance. Infinity readings do not reflect genuine data for preventive or predictive maintenance. It gives a good test term but the operator doesn’t know anything else. When the readings have drifted down into the detectable range, the maintenance worker may find themselves with little time to plan standard off-line maintenance. Extended-range testers provide for accurate readings from the moment of installation, resulting in a protracted timeline that allows maintenance employees plenty of breathing room.

3. Power Source: A battery-powered unit is preferred for operating a tester. A hand crank used byonboardd operators remains very popular.  Experienced personnel always prefer a hand crank but it is not convenient in all situations. Moreover, there is no data to prove that the hand crank is rated above battery-powered units.

4. Display: Always examine the display properly. Cheap testers may provide faulty displays which can give wrong results. Accuracy is one of the main features of the Insulation Tester, which should never be compromised. 

There are many more things to keep in mind such as Voltmeter capabilities, Ohm and kilo ohm ranges and guard terminals. One should always consider purchasing best quality testers as it is a very important device, and faulty readings can be harmful for everyone.
