Isolation Switch Tester

SwitChek

  

SwitChek is an automatic, isolation switch / circuit breaker / disconnect testing device. SwitChek tests switches that are "off" to confirm that they provide effective electrical isolation.  SwitChek aims to provide non-electrical people with a simple and safe method of verifying field based, electrical isolations before conducting mechanical maintenance.  See DeadEasy for switchboard isolation verification.

Testing can be performed on a switch or circuit breaker, thats line side, is either alive or dead, energised or deenergised.

It is simple and fast to use. No licenses are necessary. Anyone can operate SwitChek.

SwitChek tests the isolating switch or circuit breaker by injecting 500VDC on the supply side of the switch and monitoring for current leakage on the load side of the switch.  In essence, SwitChek performs an insulation resistance check across all three phases of an isolation switch. 

SwitChek is implemented in a fixed mode, that is one SwitChek dedicated to one switch or circuit breaker.  It is ideally suited to installation on large switches and circuit breakers or for frequently isolated equipment.

To operate SwitChek, press the ?Test? button. The switch is tested in 10 seconds. A green light indicates an isolating switch pass and a red light indicates isolating switch failure.

SwitChek Benefits

Users have commented that SwitChek:

  • Allows non-electricians to stress test an isolation switch.

  • Is simple to use.

  • Provides a clear result in dirty and dark environments.

  • Automatically tests the switch the moment the switch is turned off.

  • Provides remote, test result indication so that a control room operator can verify that the correct switch has been isolated. In addition, remote, test result indication provides, if logged, an audit trail to demonstrate regulatory compliance.

  • Is a whole current, confirmation of isolation method.

  • When housed in an Ex d enclosure, it is suitable for use in hazardous areas.

What is Isolation Confirmation?

Electrical Isolation Procedures / Lockout Tagout (LOTO) Procedures often require that electrical switches be tested so as to confirm that the switch is "electrically off" once the equipment has been isolated.  Confirmation or verification is often performed on the following isolating equipment:

  • Isolation Switches

  • Disconnects

  • Circuit Breakers (CBs)

Typical Isolation Procedure testing methods include:

  • Testing Dead or Test for Dead

  • Attempt Start

  • Observation of Visual Break Isolators (VBIs)

  • Pilot lamp indication of energised phases

In many cases these isolation verification methods are complex, potentially misleading and expensive to perform.

SwitChek exposes unsafe electrical isolations by detecting a failed isolation switch.
