Our 15KVPSet is a set of three voltage probes that allow direct connections up to 15,000 Vrms (15KV) 3 phase power.
Outputs from the probes connect directly to PowerSight analyzers, allowing complete analysis of medium voltage power systems up to 15KV. Hot sticks are included to provide added safety while connecting and disconnecting the probes.
Normally, professionals who wish to measure 12,470 volt lines need to locate an installed PT (potential transformer) and then connect to the low voltage output secondary of the PT. The PT ratio is entered into the PowerSight so that primary values are displayed. However, sometimes a convenient PT is not available or the measurement must bypass the PT to verify whether the metering circuit is correct.
The 15KVPSet allows direct connection between the primary voltage and to your PowerSight analyzer. The set comes disassembled in its own compact canvas carrying case.
Simply screw the "hot stick" sections together and then onto the probe. Connect the outputs to your PowerSight analyzer and to ground. Enter a 60:1 input ratio into your PowerSight analyzer and then hook the probes onto the medium voltage, keeping a safe distance with the hot sticks.
The connection to the medium voltage is via a shepherd’s hook that has a 1.4 inch inside diameter.
The 15KV probes may be purchased singly (order 15KVP). The hot sticks may be purchased separately (order STKS for 3 sections that screw together into one hot stick). The photo above shows three 15KVPs and three STKS.
Whenever possible, connect the probes to a de-energized circuit. First, connect the ground lead of each of the probes to a secure ground point.
The probes are used exclusively with the PowerSight® line of Energy Analyzers, manufactured by Summit Technology Inc.| Category | Notes |
|---|---|
| Voltage Measurement Range: | 600 to 15,000 Vrms |
| Voltage Linearity: | +/-2% over measurement range |
| Frequency Response: | Attenuation of 1db from 50 to 900 Hz (i.e. measurements attenuated 11% at 900 Hz, which is 15th harmonic at 60Hz or 18th harmonic at 50Hz). |
| Probe Dimensions: | 16.5 inches long by 1.25 inch diameter. Hook at top has 2 inch outside diameter. Threaded coupling at bottom is 5/8 inch coarse thread. |
| Shepherd’s Hook Dimensions | Connection hook at the top has 1.4 inch inside diameter. It may be replaced with a custom connection item by unscrewing and replacing with a custom accessory with ¼ - 20 threaded male coupling. |
| Pole Dimensions: | Three 18.25 inch long by 1.25 inch diameter sections which screw together for 55 inch pole length (3 poles included). |
| Total Assembled Length: | 71.5 inches from top of hook to bottom of pole. |
| Scale: | For direct reading of actual voltage, set meter for 60:1 input ratio. |
