1. BASIC INSTRUCTIONS
1.1. Delivery spot check
This manual is issued to help all the users to install and use the dielectric
strength tester for isolating oils OT2-60D, and also to help them to get the best
from it. After receiving the equipment, please check the following points:
(a) The equipment corresponds to your order specification
(b) Check if any damage was done during the shipment process
(c) Verify that you have received all the components specified on 2nd point.
1.2. Connection procedures
The manual you hold in your hands contains information and warnings that the
user should respect in order to guarantee a proper operation of all the functions
of the OT2-60D and keep its safety conditions. Also you must follow the usual
security actions.
1.3. Considerations related to the standards
All the comments and advices that you can read on this manual related to the
procedure that you must follow to do dielectric strength tests, are referred to the
IEC 156 standard, being only valid if you are following it. If you want to follow
another standard, the comments and advices of this manual can be different
(Go to 10th point).

2.2. Protection Unit
Open the equipment’s door and the protection will be inside with the others
components:
2.2.1. Test Cell
Inside the protection unit it is the test cells:
2.2.2. Gauge, Allen spanner and Fuse
Look for in the protection unit where it is the bag of fuses. Allen and
gauge are in the test cell.
The delivered gauge is 2,5 mm ± 0,05 mm in width, according to the
IEC-156 standard .

3. INTRODUCTION
The OT2-60D range is automatic equipment especially designed to test the disruptive
voltage of isolating oils in new or used transformers, cables with oil, automatic
switches, capacitors, etc.
The disruptive voltage is not a basic property of the oil, but it indicates us the degree
of contamination of this oil (water, solid materials in suspension), allowing us to decide
on the possibility of carrying out a treatment of drying and filtration, or replacing the oil.
The method that the OT2-60D uses can be applied to oils of nominal viscosity of up to
350 mm2/s at 40ºC, according to IEC-156 standard.
The OT2-60D is supplied with a complete series of protectors making it highly
protected and reliable.
It is easy to handle, all buttons or illuminated switches are on the front control panel.
The test cell is especially designed to easily change the electrodes in accordance with
the different standards in operation, the easy insertion into the registering transformer
terminals and for its complete cleaning.
