Megger TDR2010 Advanced Dual Channel TDR
Designed for the location of faults communication and pilot cables and some power supplies the TDR2000/3 and TDR2010 are tough. They are rated to CAT IV 150 V and are dust and weatherproof to IP54, so there are ready to work in the real world.
Features such as Auto setup assist the novice to get useful traces fast while the AUTO Find function assist the interpretation of the traces. For the more expert user there is the ability to manually override the auto function permitting fine tuning to enable identification of hard to determine faults.
Megger‘s new screen layout permits the operator to over lay traces, assisting in the location of faults.

Why CAT IV Rating?
A distant lightning strike can produce a transient of several kV on the supply. That transient lasts for a few tens of microseconds and is likely to do little damage.
The problem is that it may initiate an arc and this arc then presents a low impedance path for current from the mains supply. Often, that supply can deliver 1000 A or more before the breaker or other protective device operates. In that time, the amount of energy liberated is enough to start a fire or even cause an explosion. If the arc is within a test instrument there is a high probability that you will be injured or worse!
The solution is simple – design the instruments with protection and internal clearances that are large enough to prevent transients from establishing an arc and along with appropriate protection devices. Guidance to this is given in IEC61010 in order to comply with category ratings defined in IEC60664.
In practice, transients are damped quite quickly as they pass through a typical distribution system. As you can see from the diagram CATIV is recommended for use outside and to the consumer unit.
Using an instrument with a higher installation category rating does not alone create a safer working environment. You should always follow correct work practices to keep you and others safe.
