Designed to provide operating control, limit or alarm functions for transformers and load tap changers. Contacts can be factory set or adjusted as needed. The snap-action switch automatically resets when pressure returns to pre-set conditions. Pressure and/or vacuum switches can be combined on a common manifold and protected by optional enclosure. Optional pressure indicators (dial gauges) are available on select models.
The Qualitrol DGA-LT1 is a cost effective wireless transformer monitor specifically designed for monitoring failure and safety risks on distribution pad mount transformers. The DGA-LT1 automatically measures dissolved hydrogen concentration, moisture concentration and temperature of dielectric insulating oil. The monitor takes only minutes to install and requires no costly power or communications cables. Data is securely stored and analyzed on the QualConnex platform to provide alert notifications on high concentrations or high rate of increasing concentrations. The DGA-LT1 brings a cost-effective means to reduce site safety risks and prevent costs associated with unplanned outages due to failures. The DGA LT1 leverages the QGateway RF to TCP/IP for encrypted and highly secure data transfer.
CDAX 605 is a capacitance and dissipation factor test set to be used with an external power source/generator. It is a precision instrument using a combination of bridge and direct (vector) measurements and is capable of measuring capacitive, resistive and inductive loads.
Provides continuous indication of the liquid level inside of a transformer’s main tank, conservator tank or load tap changer compartment. Models available with gear driven or lever driven float mechanisms. Gear driven mechanism provides amplified pointer movement relative to corresponding float travel. Lever driven gauges offers slimmer profile for tight spaces within a transformer. Integrated switches allow for limit and alarm control functions.
