| Liquid Dielectric Test Sets are designed to measure the breakdown voltage of insulating fluids used in transformers, capacitors, bushings and related high voltage equipment. The units are portable and may be used for either on-site or laboratory testing. Three standard models rated at 60, 75 and 100 kV are available.
Testing Capability
These test sets are available with several different types of test cells which are used to hold the liquid during the test. The test sets, with the appropriate test cells, are capable of performing test to conform to the following standards: ASTM D1816 and D877, IEC 156, BS 148, VDE 0370 and other applicable standards.
We offer a complete line of test cells to accommodate all domestic and international testing standards. At the right is a chart which depicts the various electrode configurations, gap settings and voltage rates of rise required for the several standards. |

Features |
- Operating safety features include an enclosed test chamber with a transparent cover, cover safety switch and zero-start interlock on the high voltage output
- Output voltage is continuously increased from 0 to the breakdown voltage. The rate of rise may be selected at 500, 2,000 or 3000 volts per second (LD60) and 2,000 volts per second or continuously variable (LD75 and LD100)
- Single range digital meter is used to record the breakdown voltage. The meter is reset to zero with a switch
- Simplified operation is achieved with the use of cradle contacts for the test cells. The liquid to be tested is placed in the test cell. The test cell is then placed inside the test cage on the cradle contacts
- Operating controls are conveniently grouped on the front panel. These include a large, easy-to-read meter, on/off switch with pilot lamp, a rate of rise selector switch, plus a start/reset switch.
- When a breakdown of the liquid occurs, a failure lamp will light and the meter will lock on the breakdown voltage
