CircuitSpy

CircuitSpy allows any worker with a smart phone to measure voltages within a closed electrical panel.
 
CircuitSpy measures the voltages at each of its feed through terminals and reports the measurements, via WiFi, to a web browser.
 
Zero exposure to energised equipment = No electric shock risk, nor arc flash risk.  This means that working live, live electrical work and live testing is no longer necessary with CircuitSpy.
 

CircuitSpy Portable Comms Module

CircuitSpy Fixed Comms Module

 

CircuitSpy Unique Benefits

Practical for the Professional Electrician

A multichannel device for real-world three phase, single phase AC and DC voltages.  Connect to all of your test nodes in one go, close the panel door, energise, measure and diagnose the fault.

Portable and Fixed Versions

Portable Comms Module incorporates test leads, DIN rail terminal test pins and magnetic electrode connections for use in temporary installations when fault finding or commissioning.  

Fixed Comms Module incorporates feed through terminals and is DIN rail mounted, so it can be used as a direct replacement for DIN rail mount, feed through terminals for use in permament installations in hard to reach / inconvenient to access areas.  

Simple and Flexible

Web browser accessed, no special software ie App needed.  Accessible from laptop, notebook, tablet or smart phone.

CircuitSpy Other Benefits

  • Has wide application.  8 channel, CAT III 300VAC/VDC (Line to Neutral), 520VAC (Line to Line) suitable for three phase voltage measurements.
  • Is production friendly.  Test in flammable gas or dust environments without a plant shutdown and area sterilization
  • Provides access convenience.  Test in limited access areas eg working at heights (top of silos), confined space (pits) and behind machine guards
  • Perform inservice load testing.  Test on mobile equipment while in service eg gantry cranes, trucks
  • Test in Comfort.  Test remote from uncomfortable working environments eg outdoor switchboards when raining, darkness, noisy
  • Find faults fast.  Electrical status can be viewed by anyone and reported to a remote electrician potentially saving a callout
  • Robust Operation.  Suitable for use in metallic and non-metallic panels and enclosures.

CircuitSpy Background

CircuitSpy measures circuit voltages within a closed electrical panel and reports them via WiFi to a webpage.  This allows an electrical worker to measure voltages at multiple nodes within an energised circuit without exposure to energised electrical circuits, hence arc flash and electric shock hazards.  In effect it eliminates working live, live electrical work and live testing.

The CircuitSpy Portable Comms Module and connection accessories facilitate temporary installation into a switchboard or control panel.  Temporary installations are used to determine the cause of a circuit fault or allow testing of circuit function whilst commissioning.  The multichannel input module allows an electrical worker to connect to several circuit test points and measure them all, simultaneously.  Synchronised, real time readings are often vital due to circuit interrelationships.

The CircuitSpy Fixed Comms Module facilitates permament installation into a distribution board or motor control centre (MCC).  Permanent installations are used when continuous monitoring is required or access to the electrical panel is limited or incovenient.  Identifying the absense of power at a panel in a hazardous location before arranging access to the hazardous location could reduce plant downtime.  In addition, performing onload testing of inservice, mobile equipment can assist in identifying difficult faults caused by harmonic noise.  Each analog input is connected to a feed-through terminal.  In this way, CircuitSpy provides an identical arrangement to DIN rail mounted terminals meaning that it can be easily retrofitted or it consumes minimal space in a new panel.  Each measurement terminal is individually overcurrent ( fuse ) and overvoltage ( TVS ) protected.  This means that an internal CircuitSpy fault will not influence the operation of the connected external circuit and result in a nuisnce trip.

CircuitSpy Operation

CircuitSpy Configuration

Once CircuitSpy configuration is complete, the voltage at each of CircuitSpy’s terminals as well as CPU temperature is displayed.  In addition, the background colour of the voltage display changes with voltage in accordance with set threshold values.  This feature provides quick recognition of whether the terminal is energised, de-energised or energised at an abnormal level.  CircuitSpy setup is performed on the Configuration webpage, by setting the nominal voltage level eg 110V for each individual terminal and the module’s voltage mode eg AC or DC.  User defined terminal and module names may also be configured.  As an example, wire numbers may be configured as terminal names, the terminal strip number may be configured as the module name and the panel identifier may be configured as the panel name.
