It is a great tool for assessing the condition of electrical insulation in residential buildings, industry, railways and other facilities of general use. Due to its parameters - excellent performance, low power consumption from batteries, the option of charging them during measurements, convenience of use and a  high ingress protection level - it is perfect for maintenance teams, testing motors, cables, street lighting or at the construction and maintenance of  photovoltaic systems. The meter may be recommended to installers working on telecommunications and electric power systems that require the inspection of the insulation sleeve/sheath resistance (UN ≤ 30 kV) to the voltage of 5 kV applied for 5 minutes.

Features

The meter may be used to measure the insulation resistance using the adjustable test voltage up to 5000 V. When testing the cables, it automatically discharges their load at the moment of completing the measurement.

MIC-5001 allows the user to determine the insulation resistance by applying linearly increasing voltage with the slope of 1 kV/s, according to standard EEE Std 95TM-2002. This functionality is called RampTest.

In contrast the maximum test voltage, this slow and uniform method of applying test voltage protects the insulation against sudden “electrical stress”. This process may reveal defects that cannot be observed in classic RISO resistance measurement. If the tested insulation is weakened or defective, RampTest will enable the user to determine its maximum withstand voltage. In addition, this functionality is particularly useful in testing rotating machines or surge arresters.

The meter has a built-in voltmeter of AC and DC voltages in the range of up to 750 V. Extensive memory allows the device to record and send to a computer nearly 12,000 measurement results.

Furthermore, it is dedicated for measurements in areas with very high electromagnetic disturbances, e.g. electrical substations with 765 kV voltage or higher.

Capabilities

Highly efficient HV inverter, with test voltage of 5 kV and current of 6 mA, suitable for measuring the insulation resistance up to 20 TΩ. Achieving such a result makes these meters unrivalled devices. Three-wire resistance measurement, performed using a "GUARD" wire, eliminates surface leakage currents caused by contaminated insulation, thereby increasing the reliability of obtained results.

Facing the challenge

When building medium- and large-scale PV farms, designers, guided by the need to ensure the highest possible energy yield and thus the maximum return on investment, select inverters with a voltage of 1500 V DC / 800 V AC. Testing of such a system must address both the AC and DC sides of the PV system. Testing of all AC circuits must be performed in accordance with the requirements of IEC 60364-6.

The output voltage of 800 V AC, which in real conditions often exceeds this value, poses a huge problem for contractors and servicing companies, since for such high voltages there are no devices on the market to check the installation for compliance with the conditions of electric shock protection in terms of measuring the impedance of the short circuit loop.

Sonel was the first company in the world to take on the challenge of creating a fault loop impedance meter for operating voltages up to 900 V AC and measurement category CAT IV 1000 V. This is how the Sonel MZC-340-PV meter was created.

The leader does not take shortcuts

The energy released at mains voltage of 800-900 V AC can pose a danger to the personnel performing measurements. That’s why the MZC-340-PV is only wirelessly controlled.

Applications

The instrument is used for measurements in networks with rated voltage up to 900 V AC, where the prospective fault current may reach over 100 kA, as measured according to EN 61557.

Reaching the areas unattainable to others

In direct vicinity of transformers or in transformer stations, where the circuits are equipped with a high current protection (fuse-links with the rating of several hundred amperes, motor circuit breakers), fault currents may reach several hundreds of kilo-amps. Measurement of fault loop impedance in such networks requires a high-current meter, which is capable of measuring ZS values at the level of single milliohms. Our patented technical solution, which uses components not available in the commercial offer (unique fault resistor), enables us to offer the meter with perfect performance in such demanding conditions

Measurements without compromise

Commercially available fault loop impedance meters perform the measurements asymmetrically, i.e. using half-wave current. This solution introduces the transitional constant and DC constant, which does not always result in a linear behaviour of the transformer during the tests. This in turn, affects the accuracy of the results.

MZC-330S high-current meter applies symmetrical current for measurements, which means that they use the full wave - thanks to the advanced design of the measuring system and fault circuit.

Applications

The instrument is used for measurements in networks with the following rated voltage:

• up to 750 V, where the prospective fault current may reach 95,8 kA, as measured according to EN 61557.

Underground detectives

The LKZ locator set consists of a LKN transmitter and LKD detector. It allows for location, identification and tracking of the route of objects buried in the ground. It allows to trace:

• power cords and cables, control cables, telecommunications cables,
• underground elements of lightning protection systems, cathodic protection systems,
• water and sewage systems,
• fuel transmission systems (pipelines, gas pipelines)
• heating systems and pre-insulated pipes.

The sets of LKZ series are an invaluable support in earthworks carried out for various industries, including energy, installation, construction, railway, telecommunications, water and sanitary, heating, geodetic and many others.

LKN-2500 transmitter injects a locating signal into an underground object. LKD-2500 detector placed along the object traces this signal along the object. The information about position of the traced object is displayed on the Sonel LKZ Mobile app which is connected with the detector. Determination of the object’s route is possible based on observation of compass readings and the level of the detected signal.

The system has the ability to trace cables and record routes via the mobile application. Such files can be exported and shared with other users – including those who do not have the LKN-2500 / LKD-2500 device.
The system is capable of operating in passive mode (without the use of the LKN-2500 transmitter) and active mode (with the use of the LKN-2500 transmitter). The active mode allows to introduce the signal in three different methods:

• galvanic – injects tracing signal into the object directly, through crocodile clips and test leads,
• clamp – injects tracing signal into the object through an inductive clamp,
• inductive – injects tracing signal into the object inductively, using the instrument’s internal antenna.

Transmitter

• Operation in direct galvanic or inductive connection mode – internal transmitting antenna
• Compatible with transmitting clamps
• Rugged housing

Detector

• Active mode
  • work with LKN-2500 transmitter at the frequencies of 8 kHz, 32 kHz (Signal mode)
• Passive mode – work at the frequencies of:
  • 50 Hz, 60 Hz (Power mode)
  • 2...65 kHz (Radio mode)

Sonel LKZ Mobile

The application works with Sonel LKD-2500 detector. It enables tracing of objects, recording of routes in the memory of the mobile device along with GPS positions of waypoints and additional readings.

The application additionally enables:

• live positioning preview,
• measuring the distance to a specific waypoint,
• export of routes to other mobile devices,
• reading routes from the mobile device’s memory,
• preview of all recorded parameters,
• merging routes,
• adding notes to routes and measurement points.
