The Model 50132-G-01 Voltage Sensor is used to detect the presence of voltage or capacitance on overhead or underground cabling or on switch gear and MCC Panels. 
It is an excellent mistake-proof safety tester to check lines, bus bars, or capacitors before crews start to work.

Phasing Voltmeter Voltage Sensor
 

The Model 50132-G-01 Voltage Sensor has a low sensitivity range and a high capability range through 115kV. 
The range selector switch is conveniently located in a protected area on the back of the meter housing. 
The sensor operates in two general applications by providing a positive voltage indication on the exposed 
bus work and terminals, as well as on insulated cables having a capacitance test point.

Two degrees of sensitivity are offered by this unit, capacitance and direct line contact. 
The more sensitive range “Capacitance Test” will produce a minimum scale deflection at 300 volts. 
This positive, no-mistake indication is produced when the tester is applied directly to an exposed bus or terminal. Contact with the capacitance test point of a separable elbow connector carrying 25kV will also produce scale deflection. Higher voltages will produce higher deflections. When the unit is placed on “Direct Line”, higher voltages can be checked; this will allow the STB Model 50132-G-01 to be applied directly to potentials through 115kV.
This completely shielded tester reads only the contacted test point; no stray fields will be indicated. 
The Model 50132-G-01 Voltage Sensor comes in a sturdy foam-lined carrying case.
