Capacitance & Tan-Delta Measuring Equipment along with its accessories is suitable for testing motors,
Power Transformers, H.V. Bushings, Generators, Power Capacitors, cables etc. at power frequency. Periodic measurement of dissipation factor & capacitance on new solid insulators and those on long service period
produces comparative result about the trend of deterioration of insulation resistance before insulation
breakdown occurs.
Thus, the set is ideal to conduct routine diagnostic tests on solid insulating components, equipment
required for High Voltage generation, Transmission and Distribution.

The Set is in four units:
i. Capacitance & Tan-Delta Measurement Bridge
ii. High Voltage AC Power Supply Control Unit
iii. High Voltage AC Power Supply Transformer Unit
iv. Standard Capacitor

Standard test modes
1. UST - UNGROUNDED SPECIMEN TEST.
Reduces the effect of stray capacitance to ground. Maximum accuracy is obtained in this mode.
2. GST - GROUNDED SPECIMEN TEST.
Mostly used in outdoor installations, power systems when the object under test is permanently grounded. Exp. Windings of Transformer to tank and core, Coils of Rotating machine, circuit breaker assembly etc.
