Model 5895 transformer Micro-Ohmmeter 

Type 5895 Micro Ohmmeter has been specifically designed for the fast measurement of the resistance of large transformers. It is equally suitable for the measurement of any resistance where a large amount of inductance is also present. An integral timer and printer are also incorporated to enable precise readings to be recorded at exact and programmed time intervals. Whilst being practical in use the instrument also has safety features to protect both the operator and the instrument from the hazards associated with this type of measurement.

Speed of Measurement

Stable accurate measurements can be achieved in a fraction of the time required than when using more traditional bridge methods. For an average size distribution transformer the resistance reading is available within 10 seconds.

Typical Reading Times

11KV, 220 KVA Transformer 10 Seconds
132 KV, 240 MVA Transformer 40 Seconds
400KV, 220KVA Transformer 100 Seconds
